This experiment was conducted to determine the blood chemistry and carcass characteristics of broilers fed malted sorghum sprouts (MSP) or wheat offal (W/O)-based diets supplemented with yeast culture and enzyme. A total of two hundred and forty 28-day old, Marshal Broiler chickens used for the experiment were randomly allotted to 8 dietary treatment groups of 30 birds each. Each treatment group was replicated thrice with 10 birds per replicate. Data on selected blood indices and carcass traits of the birds were collected during the course of the feeding trial that lasted for 4 weeks. The experiment was a 2X4 factorial consisting of two (2) test ingredients (MSP and wheat offal) at 4 inclusion levels of enzyme or yeast (0g kg-1, +0.01gkg-1 yeast and Roxazyme G2(G) enzyme, +0.01gkg-1 yeast ,+ Roxazyme G2(G) enzyme. At the end of the trial, the effect of MSP and wheat offal inclusion showed a significant effect (P<0.05) for uric acid, WBC, Total protein, albumin and globulin. However, uric acid, total protein, Albumin and Globulin were highest for wheat offal diet. Furthermore, the results show that values obtained for white blood cell, uric acid, total protein, albumin, globulin, creatinine, ALT& AST were significantly (P<0.05) affected by the enzyme, yeast and their combination. The carcass results show that none of the parameters measured differed significantly. In conclusion, supplementation with yeast + enzyme improves total protein, albumin and globulin. Meanwhile, it reduced concentrations of uric acid, ALT and AST by broiler chickens. Therefore MSP diet should be supplemented with yeast+ enzyme or enzyme singly to improve Livestock ration for better utilisation.

The study aimed to evaluate the prevalence ofSalmonellain retail and wholesale foods in Fukuoka Prefecture, Japan. A total of 2,021 samples collected between 1999 and 2010 were tested using a culture method. Samples consisted of liquid eggs (n=30), meat (beef and pork) (n=781), offal (n=69), processed meats (n=2), seafood (n=232), processed seafood (dried fish) (n=76), vegetables (n=481), processed vegetables (n=87), fruits (n=167), and herbs (n=96) from 574 outlets and wholesale agents in 15 areas (five samples were undocumented regarding outlets). Overall, liquid egg showed significantly (P<0.001) higher frequencies ofSalmonellacontamination (13.3%) than beef (1/423, 0.2%) and pork (3/235, 1.3%).Salmonella entericasubsp.entericaserovar Enteritidis, the most common serovar as a human pathogen, were isolated from two liquid egg samples. NoSalmonellawere isolated from seafood and vegetable-related samples including seed sprouts (n=261). In conclusion, liquid egg is a significantSalmonellavehicle, showing a need to continue the vaccination of chickens to preventS.Enteritidis contamination in Japanese eggs. Moreover, further study is needed to evaluateSalmonellacontamination in seed sprouts with more sampling from retailers there.

The recent development of antibiotics-resistant pathogens in poultry, which poses a threat to human health, has necessitated the search for an alternative to antibiotic growth promoters (AGPs) to improve the gut microflora in poultry diets. One of the alternatives to AGPs is probiotics which are beneficial organisms. The by-products of the digestion of polysaccharides for which poultry do not have enzymes to digest are called prebiotics. Prebiotics serve as food for probiotics. The application of enzymes makes this digestion possible. The prebiotic potentials of enzyme supplemented high fibre feedstuffs (HFFs) are not known. This study was conducted to assess the prebiotic potential of xylanase enzyme supplemented wheat offal on broiler chickens (in-vivo). The replacement of maize with wheat offal irrespective of levels supplemented with 100ppm xylanase enzyme caused a reduction in feed intake and an increase in weight gain and better feed conversion ratio. Birds fed diet with 20% wheat offal supplemented with a xylanase enzyme outperformed birds fed diets with 10 or 30% wheat offal supplemented with a xylanase enzyme and birds fed the control diet. The birds had normal weights of vital organs with good structural consistency. The identification of microbes (fungi and bacteria) showed that dietary levels of wheat offal (10, 20 or 30% inclusion) with supplementation of a xylanase enzyme enhanced the growth of beneficial microbes, which resulted in the inhibition or elimination of the opportunistic/pathogenic microbes. It was concluded that enzyme supplementation of high fibre feedstuffs could improve the growth performance, nutrient retention and increase concentration of beneficial microbes in the guts. The use of enzymes is therefore recommended when HFFs are required as a prebiotic source in the guts of broilers.

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.

A trial was carried out to evaluate the effect of replacing wheat offal with rumen content on the growth performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks were randomly allotted to five (5) dietary treatments containing 0, 5, 10% inclusion levels of sundried rumen content and 5 and 10% inclusion levels of roasted rumen content as a replacement to wheat offal. Each treatment was replicated three times with five (5) birds per replicate in a completely randomized design experiment. The trial lasted for eight (8) weeks. The results showed that there were no significant differences in the final weights, daily feed intake, daily weight gain and feed conversion ratio at the starter phase and finisher phases. Furthermore, no significant differences in the final weight (1346.60-1508.50g), daily feed intake (83.57-100.00g), and daily weight gain (36.43-39.53g), and were observed for the overall performance. However, there was a significant difference (P<0.05) in the feed conversion ratio with the highest being 2.69g and the lowest 2.33g in the overall performance. From these findings, it could be concluded that rumen content could replace wheat offal without any detrimental effect on the performance of broiler chickens.

ABSTRACT: This study evaluated the effects of millet and corn oil additions to sorghum-based diets on the performance, carcass yields and prime cuts (i.e., wings, breasts, thighs and drumsticks) and the relative weights of edible offal (i.e., gizzard, heart, and liver) of broiler chickens. A total of 684 Hubbard Flex chickens, including 342 broilers of each sex, were housed. The design was completely randomized, and the following diets were supplied: A) sorghum and soybean meal + soybean oil (control); B) sorghum and soybean meal + corn oil; and C) sorghum and soybean meal + millet and soybean oil. Six replicates with 38 birds each (19 males and 19 females) were evaluated regarding each experimental diet. At 14, 21, 35 and 42 days of age, the feed intake, weight gain, feed conversion and viability of the chickens were evaluated. At 42 days, the live weight, carcass yield, prime cuts and relative weight of the edible offal were measured. The dietary inclusion of either millet or corn oil did not affect any of the parameters. In conclusion, additions of millet and corn oil to sorghum-based diets of broilers do not compromise poultry performance.

This study was conducted to evaluate the value of maize offal and cray fish waste meals as the main energy and protein sources respectively in broiler chicken diets. One hundred and twenty day-old Lohmann Brown broiler chicks were randomly allotted into two treatment groups of three replicates of 60 and 20 birds, respectively. Maize offal and crayfish waste meals were used to replace maize and soybean/fishmeal, respectively in the control diet (T1 ) to form (T2 ). Growth parameters monitored were final live weight, daily weight gain, feed 2 conversion ratio, internal and external body linear measurements were evaluated were statistically analysed using the studentized t-test at 5% and 1% probability. Results showed significantly (P<0.05) higher values in all the parameters apart from feed intake for birds on the control diet. The final live weight of birds on the test diet (T2 ) only reached that of the control at 10 weeks of age. The phenotypic correlation of body weight and linear body measurements for birds on both the control and test treatment diets were high and positively significant (P<0.01). However, birds on the control diet had the longest body parts than those of the test diet, likewise the internal body parts. When expressed based on percentage body weight, birds on the test diet tended to have longer external and internal body parts. It is concluded that if maize offal and crayfish waste are to be used as total replacement for maize, soybean and fishmeal, the period of broiler production should be extended from 8 weeks to 10 weeks for birds to reach market weight and with attendance lower cost of production.

Lactic acid fermentation was evaluated as a method to preserve fish and chicken by-products. Herring (Clupea harengus) by-products (viscera and heads) and chicken by-products (heads, viscera, feathers, feet and discarded whole chickens) were minced, mixed with 5% dextrose and inoculated with 108 colony forming units (cfu)/g of four different lactic acid bacteria cultures. The by-product was fermented at 25°C and evaluated for pH, % produced lactic acid, redox potential and odour during four weeks' storage. In herring offal, pH decreased from 6.8 to 4.2 in one week and stabilized at about 4.3. In the same time, 2.0% to 3.2% lactic acid was produced and concentrations stabilized from 2.5% to 4.0%. In chicken offal, pH decreased to a stable level of 4.4, and 3.2% lactic acid was produced after one week of fermentation. A negative and stable redox potential was achieved after one week of fermentation in both herring and chicken offal.

Investigations were carried out to assess the effect of lighting program and energy levels in the diet on carcass characteristics of broilers. The experiment was performed on chickens Cobb 500 hybrids for up to 42 days. The setting was reflected by the principle of two factorial experiments (2x2) at the 40 broiler carcasses of both sexes (10 per replications). The first factor was the lighting program where a group represented by the application of broiler chickens lighting 23L: 1D and group B of the regime 1. wk - 23L: 1D; 2. wk - 12L: 12D, 3. wk -14L: 10D; 4. wk - 16L: 8D; 5.wk -18L: 6D, 6. wk -20L: 4D. Another factor was the energy level where meals are in the "A" group were carcasses of broiler chickens fed diets with standard protein and energy in group "B" were the carcasses of chickens fed diets with high energy content to 0.40 ME MJ / kg compared the standard mixtures. Tests have shown that a lighting program and energy level as factors have no significant effect on carcass yield of broiler chickens, but significant differences (p <0.05) emerged as the interaction Axb and Bxa combinations of the parameters "ready to roast" and "ready to grill". The amount of abdominal fat was significantly higher (p <0.05) in group A and Axb combination compared to Bxa and Bxb. Share weight edible offal expressed as % of "carcass cut classic" was significantly higher (p <0.05) in group B. The combination of Axb had a significantly lower proportion of edible offal compared to the combination of Bxa.

Tiger nut offal is one of the common agro by products available in appreciable quantity all yaer round especially within the northern part of Nigeria. Its nutritional value is somewhat close to those of maize offal. Therefore, a 56 - day experiment was conducted to evaluate the response of broiler chickens fed graded levels of Tiger nut offal (TNO) as an energy source. Five iso-nitrogenous and iso-caloric diets tagged T1, T2, T3, T4 and T5, were compounded to contain 23 and 20% crude protein and 2800 and 3000 kcal/kg of metabolizable energy for starter and finisher phases, respectively. The TNO was included at 0, 5, 10, 15 and 20% levels in treatments, respectively such that T1 served as the control diet. A total of 200, one day old chicks were allotted to the 5 treatment groups, replicated 4 times and each replicate was allotted 10 birds. Parameters evaluated included growth rate, economics of production, blood parameters and carcass characteristics. The results showed that there was no significant variation (P>0.05) in the values obtained for growth parameters, economics of production, haematological parameters and serum biochemistry. However, there was significant difference (P<0.05) in dressed weight (1155.00 vs. 1350.00 vs. 1350.00 vs. 1525.00 and 1530.00 gbird-1 ) and shanks weight (59.50 vs. 100.00 vs. 67.00 vs. 85.00 and 60.00 gbird-1 ) which increased across the treatments as the levels of inclusion of TNO increased in the diets. Birds fed the diets 15 (T4) and 20% (T5) gave the best results compared to those fed the control and other levels. From the results of this experiment, poultry farmer can use up to 20% of TNO as a replacement for conventional energy source in the diet of broiler chickens without compromising the meat quality and health status of the birds.

This study was conducted to investigate the response of broiler chickens to diets containing cashewnut testa (CNT). Two hundred and four (204) day-old unsexed Arboracre broiler chicks were randomly allotted to four dietary treatment consisting of three replicates of seventeen chicks each. The treatments consists of a control and three other diets with CNT included at 5, 10, and 15% as a substitute for wheat offal in the control diet. Cashewnut testa had 1.5, 20.0, 54.0, 17.0, 2.0, and 94.5% crude protein (CP), crude fibre (CF), nitrogen free extract (NFE), ether extract (EE), ash and dry matter (DM), respectively. Weight gain was highest (P < 0.05) in birds fed 5% CNT diet (35.24g) while the lowest and feed: gain ratio values. The CP retention and digestible EE, CF, NFE, ash, DM and total digestible nutrient were not significantly (P <0.05) affected by CNT in the diets. The serum metabolites were significantly (P < 0.05) affected by the levels of CNT in the diets. Total serum protein increased (P < 0.05) with increasing level of CNT in the diets. Among the carcass parameters measured, breast, neck and back weight were highest (P < 0.05) for 5%CNT diet while abdominal fat, small intestine and large intestine weight increased (P < 0.05) with increasing levels of CNT in the diets. No significant effect (P > 0.05) in juiciness, flavor intensity, tenderness and off flavor was recorded among the meat samples from the broiler fed the diets. Meat lipid and ash increased (P < 0.05) in the CNT diets. Cost of feed per kg decreased while cost of feed per kg live weight gain increased (P < 0.05) with increasing level of CNT in the diets. It was concluded that 5% CNT could replace wheat offal in broiler diets.

Nutritional value of dietary raw bambara nut offal fortified with enzyme (Natuzyme ) on the performance of broiler chickens were investigated. Two hundred and fourty (240), unsexed one day-old commercial broiler chicks (Marshal Strain) were randomly divided into eight groups of 30 birds each. The groups were randomly assigned to eight iso-caloric and iso-nitrogenous diets in a 2 × 4 factorial arrangement involving four levels (0, 10, 20 and 30 %) of raw bambara nut offal and 2 enzyme levels (0 and 0.025 %). Each treatment was replicated three times with ten birds per replicate. There were significant differences (P < 0.05) among treatments in AFW, ADWG, ADFI, FCR and PER. Chickens fed 10 % BGO without ® Natuzyme had higher (P < 0.05) FBW, ADWG and ADFI than chickens fed 0, 20 and 30% BGO diets. Least (P<0.05) ADFI and better FCR was recorded on broiler chickens fed control diet and 20 % BGO with enzyme. respectively. Addition of enzyme improved (P < 0.05) AFW and ADWG at 20 and 30 % BGO level. Significantly (P<0.05) higher AFW, ADWG and ADFI revealed that inclusion level of BGO at 10 % did not pose any deleterious effects on the birds. There were significant (P < 0.05) differences among treatments in the digestibility of dry matter (DM), crude protein, crude fibre (CF), ether extract (EE) and nitrogen-free extract (NFE). There was no interaction (P>0.05) between enzyme and BGO across the dietary treatments. Significant (P < 0.05) differences were observed in all the blood profile parameters observed across the dietary treatments except eiosinophil concentration. It was concluded that up to 30 % BGO can be included in enzyme supplemented broiler finisher diet without adverse effects on the performance, nutrients digestibility and blood profile of broiler finisher chickens

The main goal of the article is to present the Polish chicken market in 2012-2017 in the context of changes in foreign trade in chicken products. In order to achieve the goal, the methods of descriptive statistics (comparative analysis over time, structure analysis, linear trend function) were used. In the analyzed period, there is a tendency to increase the positive balance of trade in meat, offal and chicken preserves, while the balance of live poultry was negative. In the years 2012-2017, with a significant increase in the stock of chickens (except laying hens), there was over 58% increase in their slaughter, and the export of chicken products (live hens, meat, offal, preserves) increased more than twice. In export and consumption, chicken products dominate, followed by turkey products. The production of live chicken is very concentrated.

An experiment was conducted to evaluate the replacement value of poultry visceral offal meal (PVOM) substituting for fish meal (FM) on an equal protein basis in the diets of unsexed Ross-strain broiler chickens from day-old to 8 weeks of age. One hundred and fifty birds were allotted in groups of 10 into 15 equidimensional floor pens with floor space of 0.189m2 per bird. There were three replicates per treatment diet, with 10 birds per pen serving as a replicate. Five treatment diets, each for the starter and finisher phases of 5 and 3-week duration respectively were fed ad libitum. Diet A (control) contained 8% FM which was gradually replaced with PVOM at 2,3,4,6,6,90 and 9.20% in diets B, C, D and E respectively for both phases. All the diets were isocaloric (ca 12MJ ME/kg) for both phases and isonitrogenous with 23 and 20% dietary crude protein contents for the starter and finisher diets respectively. Feed intake and feed conversion rations (FCR) were similar (P >0.05) on all diets in support of complete substitution. However , weight gain for 8 weeks on the control diet was better (P <0.05) than those on FM/PVOM- and PVOM-diets whose weight gains were similar (P < 0.05). The mean feed intake values of 4.031, 3.936, 3.760, 3.870 and 3.715 kg/bird were obtained for birds receiving diets A,B,C,D and E respectively while the equivalent FCRs were 2.326, 2.352, 2.233, 2.326 and 2.340. The mean weight gains for birds on diets A,B,C,D and E for 8weeks were 1.824, 1.688, 1.689, 1.676 and 1.590 kg/bird respectively. The dressed weight and weight of back, drumsticks, things and wings were similar (P >0.05) for all diets in favour of complete substitution of FM with PVOM. Mean dressing percentages were 58.24 to 69.07% . It is concluded that PVOM could replace FM completely in broiler diets.

Effect of alum-treated groundnut (Arachis hypogea) shell (ATGNS) meal was studied on the blood chemistry and carcass characteristics of broiler chickens. Two hundred and forty (240) day-old broiler chicks of Anak strain were used for the study in a completely randomized design for eight weeks. The chicks were allotted into six groups of forty chicks each and further divided into four replicates of ten chicks each.Groundnut shell (GNS) was processed by soaking it in water containing alum in ratio 1kg of groundnut shell: 15 litre of water: 600g of alum for three, four, five and six days. Wheat offal was included at 10% in T1 as positive control, 4% wheat offal and 6% untreated groundnut shell (GNS) in T2 as negative control, and 4% wheat offal with 6% treated GNS in treatments 3, 4, 5 and 6 at three days, four day, five days and six days of processing respectively. Results on haematological parameters were not significantly (p>0.05) different except mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). Birds in T5 performed better than others in mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) with highestvalues of 123.83% and 41.93pg respectively, while birds in T3 had the lowest values of 115.28% and 39.05pg in the two parameters respectively. There were significant (p<0.05) differences in serum total protein, albumin and globulin, while other parameters measured showed no significant (p>0.05) differences in serum biochemical studies. Birds fed treatment 1 (T1) had the highest values of 3.95 and 2.72g/dl in total protein and globulin respectively, while the lowest values 2.55 and 0.97g/dl were obtained from birds in T6 respectively. Cut-up parts showed significant (p<0.05) differences in head, neck, back and thigh across treatment means with the exception of other parameters considered. The live weights of birdson processed groundnut shell meal, although not significantly (p>0.05) different, were better (p<0.05) than those on untreated groundnut shell meal (T2). Birds in T6 had the highest values (2.95, 4.60 and 12.53%) in head, neck and thigh respectively. The highest weight (18.02%) of back was recorded in T1. Birds in T4 had the highest values of 19.60 and 4.20% in breast muscle and shank respectively, while those in T3 recorded the lowest (14.65%) in breast muscle, and those in T2 had the lowest (3.56%) in shank. The results in conclusion, showed that alum-treated groundnut shell(ATGNS) could replace wheat offal at 6% level of inclusion by improving carcass yield as well as maintainingblood profile of broiler chickens.

Abstract At present, modern high-yielding crosses of broiler chickens are used to produce high-quality meat with high technological and consumer properties. To assess the meat productivity of broiler chickens grown on fodder produced in the conditions of the poultry factory at our own feed factory, a control slaughter was carried out at the age of 42 days. Analysis of the data obtained shows that with an average poultry live weight of 2000 ± 50 g, the slaughter yield of broiler chickens was 71.8 ± 0.13%. At the control slaughter, we found that the weight of the gutted carcass was 75.23%, offal 10.32%, and technical waste 14.45% (Figure 1).When studying the quantitative and qualitative composition of by-products, we found that liver accounted for 18.42%, stomachs 7.47%, heart 3.39%, neck 12.59%, legs 33.9%, heads 24.23 % by weight of offal.In the structure of technical waste feather is 24.92%, blood is 32.87%, intestine is 42.21% (Figure 3).Thus, the results of our research show that when cutting broiler chickens grown on self-made feeds under the conditions of modern poultry enterprises with a closed production cycle, gutted carcass weight is 75.23%, while legs and heads constitute the main bulk of the mass of by-products.

Summary. Data on the effect of mycotoxins on the organism of broiler chickens, and the indirect effect of offal obtained from poultry, fed with mixed feed infected with mycotoxins, that people eat were analyzed in the article. In particular, it has been proved that in experimental DON-toxicosis and experimental citrinin-toxicosis in broiler chickens, these toxins are able to cumulate in organs and tissues and cause clinical and pathological changes. DON exceeded the maximum allowable level for chickens more than 2 times, citrinin exceeded the MDL by more than 20 times. In the first experimental group, the incidence rate of poultry reached 83.3% by the 7th day of feeding and mortality - 52.2% of the number of cases. During the autopsy of the dead chickens it was found that the liver was blood-filled, with areas of necrosis, the gall bladder was full of bile, the muscular wall of the atria was thinned. At experimental citrinin toxicosis, as well as in the first experimental group, diarrhea with an admixture of blood was observed in chickens. At the autopsy there was inflammation of the small and large intestines, the liver was blood-filled, and the intestines were hyperemic. For deoxynivalenol, the fact of accumulation of this mycotoxin in the tissues of the organs of chickens of the 1st group was reliably established. The data on the accumulation in the organs and tissues of broiler chickens of other mycotoxins in our experiments were unreliable and require additional studies.

The aim of the study was to determine the presence of Campylobacter strains in poultry by-products and define antimicrobial resistance of isolates. In total, 400 samples were tested among which 300 included the liver, heart and stomach, and 100 samples represented the contents of the cecum. The samples were taken from chickens and turkeys in the slaughterhouse after evisceration. The prevalence of Campylobacter in chicken samples was 100% with regards to the contents of cecum and offal. The turkey origin Campylobacter strains were noted in 76% of the livers, 78% hearts and 82% gizzards. The samples of cecum contents were positive in 60%. Species analysis of the strains isolated showed C. jejuni as dominant. The estimation of sensitivity to antibiotics showed that Campylobacter strains were most frequently resistant to quinolones and tetracyclines. Resistance to ciprofloxacin was detected among 52.7% and 52.5% chicken and turkey origin strains. The same was noted regarding nalidixic acid, resistance to which was shown in 56% and 58.5% isolates, respectively. Regarding tetracyclines, the highest resistance of the strains from chicken and turkey was detected to doxycyclinum in 61.3% and 53.3% of isolates, respectively. However the highest sensitivity was showed to erythromycin, gentamicin and chloramphenicol. Only one C. coli strain from turkey offal was resistant to gentamicin. Simultaneously multi drug resistance was defined. The aimed studies showed that 62% of C. jejuni and 53.8% of C. coli strains from chicken offal were resistant to two or more agents. In turkey origin isolates MDR was detected in 54.7% of C. jejuni and 53.3% of C. coli strains.

A number of alternative feedstuff that are affordable and profitable for use in developing countries for animal feeding have been identified and reported. However, some of these alternative feedstuff have low nutrient density, and some with high nutrient density are difficult to process and or preserve. However, it is reported that two different alternative feedstuff could be mixed to improve the nutrient density of the mixture, and be preserved better at the same time. Mango fruit reject pulp has high energy content but cannot be easily sundried and preserved alone, except a carrier is involved. Four (4) experiments were conducted to determine the proximate composition and energy content of mango fruit reject pulp-maize offal mix meal (MFRP-MO); effects of MFRP-MO on growth performance and economics of productions for starter and finisher broiler chickens, carcass characteristics, internal organs and gastro-intestinal tract (GIT) morphometry of finisher broiler chickens. Mango fruit rejects pulp-maize offal mix meal (MFRP-MO) partially replaced maize at 0, 20, 40, 60, and 80% respectively to produce diets coded T1 (0%), T2 (20%), T3 (40%), T4 (60%), T5 (80%), and T1(0%). One hundred and eighty (180) day-old Marshall broiler chicks were grouped into five, with each group replicated three times and a replicate contained 12 birds in completely randomized design (CRD); which were exposed to the diets in a feeding trial that lasted for 28 and 49 days for starter and finisher phases respectively. MFRP-MO contained 9.63% CP, 68.38% NFE and 3320. 41kcal/kg ME. Results of mean growth performance parameters for starter and finisher phases declined from 40% and 20% MFRPMO respectively on parameters including final weight, daily weight gain and FCR. Economic indices were better at 80% MFRP-MO mix replacement of maize; the cost per kg weight gain steadily declined. Percentage feed costs were 32.36 to 39.92% and 53.50 to 62.75% for starter and finisher respectively. The dress percent, major carcass cuts and internal organs were not significantly different. With the exception of large intestine length, which was not significantly different (p<0.05), caeca and small intestine varied in opposite directions: small intestine decreased, while caeca increased as MFRP-MO mix increased. It was concluded that 20% replacement of maize by MFRP-MO mix was optimal for both starter and finishing broiler chickens' growth but 60% was more economical and 60% MFRP-MO mix was recommended.

An experiment was conducted to investigate the effect of exogenous enzyme supplementation on the utilization of rice bran as a replacement for wheat offal by meat-type chicken. A total of three hundred and twenty day-old Marsha strain broiler chickens were randomly allocated to eight dietary treatments. Each dietary treatment had 40 birds with 10 birds in each replicate. The wheat offal in diets was replaced by rice bran (RB) at four levels (0%, 10%, 20 % and 30%). Each diet contained 2853.10, 2837.90, 2822.70, and 2807.50 ME Kcal/kg and Crude Protein% of 21.68, 21.57, 21.47 and 21.36. The diets were in two groups. One group was supplemented with exogenous Enzyme while the other group was not supplemented with enzyme. The growth performance, serum biochemistry and organ weight were estimated Data obtained were subjected to Analysis of variance in a 2 x 4 factorial arrangement, Results showed that the final body weight gain was significantly higher (P at this level. Birds fed 30% rice bran inclusion level had significantly lower (P Protein, Globulin and Serum Glutamate Oxaloacetate Transaminase (SGOT). Birds on diet containing level of rice bran had high total protein, Globulin and SGOT [t was concluded that 30% rice bran With enzyme supplementation had no adverse effect on the performance, serum biochemistry and internal organs of the birds.

The experiment was conducted to evaluate the effect of dried bloodrumen content mixture (DBRCM) on carcass characteristics of broiler chicks to replace soybean meal (SBM). A total of 225 unsexed day old broiler chicks (SASSO C44) were randomly distributed to five dietary treatment groups in a completely randomized design. Each treatment was replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100%SBM+0%DBRCM (T1), 80%SBM+20% DBRCM (T2),60%SBM+ 40% DBRCM (T3), 40%SBM+60% DBRCM(T4) and 20%SBM+80% DBRCM (T5) in 56 days of age. At the end of the experiment, two male and two female birds per replicate were used to determine carcass characteristics. The result revealed that the edible carcass yield ranged from 977.9-1159.3g. The dressing percentage based on the edible carcass weight was 63.9 % (T1), 66.6 % (T2), 65.4 (T3), 64.2% (T4) and 63.1% (T5). There was no a significant difference (P>0.05) in both edible carcass yield and its dressing percentage. The commercial carcass weight was 937.4g (T1), 984.7g (T2), 962.0g (T3), 925.0g (T4) and 833.1g (T5) and the dressing percentage was 54.9%, 56.6%, 55.3%, 53.7% and 53.7% for T1, T2, T3, T4 and T5, respectively. Significant difference (P>0.05) was not observed in commercial carcass yield and its dressing percentage among the treatment groups. There was no a statistical marked difference (P>0.05) in total nonedible offal and edible offal. Females had more (P<0.05) breast meat than that of males. The abdominal fat and abdominal fat percentage were not significantly influenced (P>0.05) by a diet containing DBRCM. However, abdominal fat and its fat percentage were higher (P<0.05) in females than males. Based on this result, it could be concluded that DBRCM can replace soybean meal up to 80% substitution level without any adverse effect on carcass characteristics.

A feeding trial was conducted for 56days to investigate the effect of neem (Azadirachta indica) leaf meal on the growth performance and carcass traits of broiler chickens. The neem leaf meal was used in replacing parts of wheat offal in the diets of 192 day-old broiler chickens fed ad libitum at 0.1, 0.2 and 0.3% levels of inclusion. The experimental birds were randomly distributed into four treatments. Each treatment was sub-divided into three replicates of sixteen (16) birds. Medications were administered only to the birds in treatment 1(control group) while vaccination was administered across the treatment during the course of the experiment. Growth parameters were taken on weekly basis and data obtained were subjected to one way analysis of variance (ANOVA) in a completely randomized design. There was a significant (P<0.05) effect of varying dietary inclusion of NLM only on average weight gain among the birds at the starter phase. Groups fed 0.3% NLM recorded the highest average weight gain (430.63g) as against 421.00, 392.57 and 394.97g recorded for the control, 0.1% and 0.2% NLM groups, respectively. Neem leaf meal had nosignificant (P<0.05) effect on broiler performance at the finisher phase across the treatment groups. Mortality was not affected (P>0.05) at any of the growth phases. Carcass traits; cut-parts (except neck) and organs showed no influence (P>0.05) of NLM inclusion. It can then be recommended that the neem leaf meal inclusion up to 0.3% in the diets of the broiler chickens can be used as growth promoters during the chick phase of growth.

A preliminary study was carried out to determine the prevalence of Aflatoxin B1 (AfB1) contamination and common moulds growing in some selected poultry feed raw materials in Zaria. Five different feed raw materials:Maize (MZ), soybean cake (SBC), groundnut cake (GNC), brewers dried grain (BDG) and maize offal (M/O), were collected from four feed mills and the open market. The common moulds isolated from the samples were Mucor spp., Aspergillus spp., Fusarium spp., Penicillum spp., Curvularia spp. and Rhizopus spp. AfB1 contamination showed that maize and soya bean cake were less than the 20 parts per billion (ppb) permissible limits for AfB1 in poultry feed ingredients, while BDG, M/O and GNC were 40, 60 and 80 % respectively above 20 ppb permissible limits. A feeding trial was conducted to evaluate the response of broiler chickens to Mycofix a toxin binder. Three hundred and thirty Ross, 1-day old broiler chicks were assigned to five dietary treatments, each with three replicates of 22 chicks per replicate in a completely randomized design (CRD). Treatment 1 was the control diet without Mycofix while treatments 2, 3, 4 and 5 had Mycofix included at 100, 200, 300 and 400 g /100kg diet, respectively at both starter and finisher phases. Experimental diets and water were given to the birds ad libitum during eight weeks of the feeding trial. Data were subjected to Analysis of Variance (ANOVA) using General Linear Model procedure of SAS and significant differences among treatment means were compared using Dunnette test of significance. Results of the starter phase showed that birds fed 400 g/100kg Mycofix diet had the best final body weight (902.67g), weight gain (839.67g) and average daily weight gain (29.98g). Birds fed 200 g /100 kg Mycofix had the lowest feed conversion ratio of 1.6 and the least cost per kilogram gain(₦138.52).At the finisher phase birds on 400 g/100kg Mycofix diet had the best final weight (2345.3g), weight gain (1403.3g), average daily gain (50.1g), feed conversion ratio (2.1) and least feed cost per kilogram gain (₦167.20). It may be concluded that addition of Mycofix to diets of broiler chickens at 400g/ 100kg at both starter and finisher phases of the study improved performance significantly and gave the least cost of production.

Watermelon rind is one of the several unwanted by-products generated by restaurants, fruit juice producers and food industries in Nigeria that can be gotten rid of by using it as an energy source in broiler production. The growth performance and apparent nutrient digestibility of broilers fed diets containing varying inclusion levels of dried watermelon rind (DWMR) in replacement for wheat offal as source of energy and fibre at starter phase was evaluated. The dried watermelon rind was prepared by sun-drying fresh watermelon for three days and oven-dried at 50 ºC for 2 hours. The birds were randomly allocated to five (5) treatments (T1 – T5), each treatment had three replicates with ten (10) birds per replicate. The birds were fed varied levels of DWMR at 0 %, 25 %, 50 %, 75 % and 100 % in replacement of wheat offal to obtain five diets. Feed and water were provided ad-libitum throughout the 28 days study duration. Body weight, Body weight gain, Feed intake, Feed conversion ratio and apparent nutrient digestibility were measured. The results obtained on the growth performance shows no significant (P>0.05) difference of the growth parameters across treatments. However, there was significant (P<0.05) difference in the digestibility of Crude fibre, Ether extract, Ash, Nitrogen free extract and Total digestible nutrient across treatments. There was no obvious variation in dry matter and crude protein digestibility. The result of the total digestible nutrient was significantly (P<0.05) higher in T2 (92.90 %) than the T1 (84.99 %) which was the control diet. The crude fibre digestibility recorded in T2 (63.48%) and T1 (61.09 %) is higher than T5 (43.00 %), the ether extract digestibility of T1 (96.42 %) is higher than the other groups with the lowest in T4 (95.25 %). There was depress ash digestibility in T5 (68.30 %), lower than the other groups with the highest in T1 (82.59 %). The study therefore concluded that farmers can replace wheat offal with 25 % watermelon rind in broiler starter diet without any deleterious effect in the growth performance and nutrient digestibility.
 
 
 La croûte de pastèque est l'un des nombreux sous-produits indésirables produits par les restaurants, les producteurs de jus de fruits et les industries alimentaires au Nigéria qui peuvent être débarrassés en l'utilisant comme source d'énergie dans la production de poulets à griller. La performance de croissance et la digestibilité apparente des éléments nutritifs des poulets de grillage nourris selon des régimes alimentaires contenant différents niveaux d'inclusion de la croûte de pastèque séchée (DWMR) en remplacement des aals de blé comme source d'énergie et de fibres à la phase de démarrage ont été évaluées. La croûte de pastèque séchée a été préparée par pastèque fraîche séchée pendant trois jours et séchée au four à 50ºC pendant 2 heures. Les oiseaux ont été attribués au hasard à cinq (5) traitements (T1 - T5), chaque traitement avait trois répliques avec dix (10) oiseaux par réplique. Les oiseaux ont été nourris à des niveaux variés de DWMR à 0 %, 25 %, 50 %, 75 % et 100 % en remplacement des aals de blé pour obtenir cinq régimes alimentaires. L'alimentation et l'eau ont été fournies ad-libitum tout au long de la durée de l'étude de 28 jours. Le poids corporel, le gain de poids corporel, l'apport alimentaire, le rapport de conversion des aliments pour animaux et la digestibilité apparente des nutriments ont été mesurés. Les résultats obtenus sur la performance de croissance ne montrent aucune différence significative (P>0.05) des paramètres de croissance entre les traitements. Cependant, il y avait une différence significative (P<0.05) dans la digestibilité des fibres brutes, extrait d'éther, cendres, extrait sans azote et nutriment digestible total entre les traitements. Il n'y avait aucune variation évidente dans la matière sèche et la digestibilité brute de protéine. Le résultat du nutriment digestible total a été significativement (P<0.05) plus élevé en T2 (92.90 %) que le T1 (84.99%) qui était le régime de contrôle. La digestibilité des fibres brutes enregistrée en T2 (63.48%) et T1 (61.09 %) est plus élevé que T5 (43.00 %), la digestibilité de l'extrait d'éther de T1 (96.42 %) est plus élevé que les autres groupes ayant le plus faible taux de T4 (95.25 %). Il y avait une digestibilité déprimante des cendres en T5 (68.30 %), inférieure à celle des autres groupes ayant le taux le plus élevé en T1 (82.59 %). L'étude a donc conclu que les agriculteurs peuvent remplacer les aals de blé par 25 % de croûte de pastèque dans le régime de démarrage des poulets à griller sans aucun effet délétère dans la performance de croissance et la digestibilité des nutriments.

Two experiments were conducted with golden Hubbard pullet chicks to investigate the replacement effects of locally prepared fish silage for imported fish meal in pullet and layers' rations. Acidic and neutral fish silage preparations concentrated with either maize or cassava plus groundnut meal and wheat offals, were fed as a substitute for fish meal. Results with pullets showed good feed consumption for all dietary treatments but feed efficiency was decreased (P<0.05) for neutral cassava, acidic maize and acidic cassava fish silage treatments. Pullet mortality was between 0.18 and 4.17%, being significantly (P<0.05) highest in the acidic fish silage diets. Lipid retention, metabolizable energy (ME) and efficiency of energy utilization (ME%) were similar across all treatments except for neutral maize fish silage, in which ME was slightly high and lipid retention low. Egg production and egg size significantly (P<0.05) decreased among groups of birds fed acidic maize acidic cassava and neutral cassava fish silage diets. Similarly, the efficiency of feed conversion to eggs decreased (P<0.05) in all fish silage substituted diets.

A 5-week experiment was conducted to investigate the effects of qualitative feed restriction through the use low-quality diet on finisher broiler performance, and to determine if sufficient compensatory growth can be achieved at that phase of broiler production. Seventy two (72) 4 weeks old broiler chicks of Anak strain weighing of the average 1.0kg were randomly distributed into two groups, A and B, using completely randomized design. Each group was replicated 3 times with 12 broiler chicks per replicate and each replicate housed in a pen measuring 1.5 m x 2 m. Broilers in group A were given a standard broiler finisher diet continuously for 5 weeks while broilers in group B received a low-quality cheap diet based mainly on palm kernel cake and wheat offal for the first two weeks and then placed on the standard diet for the remaining three weeks of the trial. The birds were weighed at the beginning of the trial and weekly thereafter. At the end of the feeding trial, 4 birds were randomly selected from each group, weighed, sacrificed, de-feathered, eviscerated and their internal organs as well as the abdominal fat, weighed. There was no significant difference in feed intake between the groups (P>0.05) at the end of the trial but the group on the high fibre low-quality diet consumed significantly (P<0.05) more feed during the 2 weeks. Daily body weight gain of the birds on the low-quality diet was lower than that of their counterparts in the control diets in the first 2 weeks but remarkably and progressively increased up to the end of the feeding trial. There was, however, no significant difference between the groups (P>0.05) in the final body weights. There were no significant differences in internal organ weights of the groups (P>0.05). However, abdominal fat weight was significantly (P<0.05) reduced by qualitative feed restriction. Feed cost of production (N/kg weight gain) were N348.69 and N343.78 for the control and qualitative feed restricted groups, respectively. The results have shown that sufficient compensatory growth can be achieved in broiler production the period of production is just 5 weeks.

SUMMARYThere are an estimated 277 000 cases of campylobacteriosis in Australia each year, most of which are thought to be sporadically acquired. To explore causes for these infections, we conducted a multi-centre case-control study of patients and community controls across five Australian States during 2001–2002. A total of 881 campylobacter cases and 833 controls aged ⩾5 years were recruited into the study. Crude logistic analyses were conducted within various food and non-food exposure groups. A final most parsimonious multivariable logistic regression model was developed and adjusted odds ratios (aOR), 95% confidence intervals (95% CI) were derived together with adjusted population attributable risks (PAR). Consumption of undercooked chicken (aOR 4·7, 95% CI 2·6–8·4) and offal (aOR 2·0, 95% CI 1·0–4·0), ownership of domestic chickens aged <6 months (aOR 12·4, 95% CI 2·6–59·3) and domestic dogs aged <6 months (aOR 2·1, 95% CI 1·1–4·2) were found to be independent risk factors for illness in the final model. The PAR proportions indicate that eating chicken meat, either cooked or undercooked may account for approximately 30% of campylobacter cases that occur each year in Australia. These results justify the continued need for education of consumers and foodhandlers about the risks associated with the handling of raw chicken and the potential for cross-contamination.

<p>Entomopathogenic nematodes belonging<br />to genera Steinernema and Heterorhabditis are potentially<br />most effective and safe biological control agents for insect<br />pests, especially for soil dwelling insects and those living in<br />cryptic habitats. Field application of the nematodes is still<br />hampered by supply of large number of infective juvenile<br />(IJ) nematodes. Five published in vitro media along with its<br />two modifications were tested for mass propagations of two<br />indigenous nematodes (H. indicus PLR2 and Steinernema<br />T96) and one commercial strain (S. carpocapsae #25).<br />Varying levels of IJ yields were observed across the<br />replications and experiments. Medium F that contained 1.0%<br />yeast extract, 2.5% egg yolk, and 4.0% soy oil yielded the<br />highest IJ numbers of H. indicus PLR2 (1.5×105 IJ ml-1) and<br />of S. carpocapsae #25 (2.9×105 IJ ml-1), whereas the widely<br />used medium B, which is based on homogenized chicken<br />offal (40%), yielded the highest number of Steinernema T96<br />(5.8×104 IJ ml-1). The IJ’s quality, as measured by their<br />morphometrics and pathogenicities, were generally<br />impaired, indicating the lack of essential nutrient(s) in the<br />media. Optimization of the propagation media is therefore<br />still needed to increase IJ’s quantity and quality to achieve<br />the required standard for commercial scale of artificial<br />propagation.</p>

Introduction: Bacteria of the genus Salmonella are important pathogens involved in the contamination of various foods, such as chickens, and may cause food poisoning. Aim: The present study aimed to review the literature on the prevalence of chickens contaminated with Salmonella spp., which are commercializated in different Brazilian states. Material and methods: This was a literary review. The absolute frequency and the total percentage of contaminated samples was calculated and the Qui-square statistical test was applied, considering statistically significant p <0.05. Results: 616 publications were retrieved, but only 10 articles were included to compose the results. The cataloged studies were carried out in 14 different brazilian states, and it was observed that of 5,030 chicken samples analyzed, the mean prevalence of samples contaminated with Salmonellawas 7,3% (n= 365). In addition, the prevalence of samples in the different studies ranged from 2.5% to 44.6%. The most prevalent serotype was S. Enteritidis (28,7%) and a statistically significant association between the type of raw material for commercialization and the result of the chicken samples microbiological analysis was observed (p<0.001), where the carcasses represented 90.1% of the contaminated samples. Conclusion: Thus, the data presented in this study can serve as subsidy for the development of necessary, political or legislative, measures that allow a better control of commercialized chickens in Brazil.Descriptors: Salmonella; Foodborne Diseases; Epidemiology.ReferencesSouza GC, Gonsalves HRO, Gonsalves HEO, Coêlho JLS.

AbstractPasture-raised poultry (PP) production systems allow chickens, turkeys or other poultry types to be raised entirely on pasture or in small, open-air moveable pens with access to fresh pasture daily. With an increase in consumer demand for poultry products produced using more humane and potentially environmentally sustainable practices, PP production systems are regaining popularity among farmers across the USA. The majority of research on PP is related to meat quality and forage conditions while the environmental effects have remained largely unstudied. The rotation of poultry on pasture is one of the primary best management practices (BMP) used to avoid over grazing and buildup of excess nutrients and pathogens; however, BMPs for handling and processing of the associated wastes (i.e., wastewater, feathers, offal) related to on-farm processing and mobile poultry processing units (MPPU) are not as well established. Therefore, a study with PP growers in the southern USA was initiated to provide important baseline information on the potential environmental impacts of processing methods used by PP production systems. Here, three farms utilizing on-farm processing were sampled over a 9-month period and two farms utilizing a MPPU pilot plant were sampled over a 3-month period. Soil, compost and wastewater samples were collected during each sampling date for on-farm processing while only wastewater was collected at the MPPU pilot plant. Soil samples (24-cm cores) were analyzed for total nitrogen (TN), Mehlich-3 extractable phosphorus (M3-P) and moisture content. Compost derived from processing wastes was analyzed for TN, total phosphorus (TP), water extractable P and moisture content. Wastewaters were analyzed for total Kjeldahl nitrogen (TKN) and TP. Soil TN levels (0.075–0.30%) reported here are comparable with TN levels reported for various soils in the Southeastern USA while M3-P was generally below levels found in agricultural soils subject to conventional poultry litter application based on previously published data. Conversely, TN and TP levels—0.3 to 1.3 and <0.4%, respectively—in compost were well below recommended values (i.e., approximately 2% each of N and P) for compost highlighting an opportunity for PP growers to create a more useful compost for land application. Last, wastewater collected from both, on-farm processing and the MPPU measure TKN and TP levels were much less than conventional processing. Overall, the present study provided baseline data on soil and compost nutrients related to on-farm poultry processing as well as wastewater composition for on-farm processing and MPPUs.

A feeding trial of six weeks was conducted to determine the effect of including rice offal supplemented with natuzyme on the performance of broilers. One hundred and seventy two 2 –week old broilers of mixed sexes were randomly allocated to four diets in a completely randomized design. The broiler chicks were allocated one of four diets containing either 0 (control), 5, 10, or 15% of rice offal. The starter diets were isonitrogenous (25% CP) but decreased in energy levels from 2,779.32 (Diet A), 2,747.73 (Diet B), 2,715.54 (Diet C) to 2,683.54kcal/kg ME (Diet D). The finisher diets were also isonitrogenous at 21% CP with each diet replicated three times. The energy levels of the finisher diet decreased from 2801.67 (diet A) to 2703.22 kcal/kg ME (diet D). The energy levels on diets B (2768.72) and C (2736.18) were higher than on diet D. All diets containing rice offal were supplemented with natuzyme at 100g/100kg feed. Overall result showed that feed intake was significantly lower (p<0.05) on the control (117.38g/bird/day) than on diets B (123.57), C (125.24) and D (123.97g/bird/day). Weight gain was significantly higher (p<0.05) on diet B (57.64g/bird) than on diets C (50.77) and D (46.88g/bird) respectively. Water intake was significantly lower (p<0.05) on the control (204.60mL/bird) than on diets B (240.44), C (231.86) and D (225.73mL/bird), respectively. Feed conversion ratio was significantly better (p<0.05) on diets A (2.36), B (2.23) and C (2.68) than on diet D (3.06) only. Feed cost/kg gain was significantly (p<0.05) better on diet A (N532.65) than on diets B (N666.75) and C (N688.92) only. Initial weight did not differ significantly across the diets but final weight was better (p<0.05) on diet B (2644.40g/bird) than on the control and other rice offal diets. Even though the control diet had lower feed intake, birds on diet B had better weight gain, feed conversion ratio, feed cost/gain and final body weight than the control and other rice offal diets and is therefore, recommended. This is because rice offal based diet on diet B has a cost saving of 8.33% over the control diet.

Probiotics is a feed additive in the form of life microorganisms that balance microorganism population in the digestive tract. This research was conducted to study the effect of addition of probiotics product into drinking water on percentage of carcass,body fat and edible offal. One hundred and fifty birds of day old chicks (DOC) of “Hybro-AM” strain were divided into 5 groups of treatments. The treatments were R0 (control diet+ drinking water without probiotics), R1 (R0 + Temban), R2 (R0 + Biolacta), R3 (R0 + Biovet), and R4 (commercial diet). Chicken were given diet and drinking water ad libitum. Percentage of carcass, boy fat and edible offal (heart, gizzard, lever, andcaecum) measured when 35 day old broiler chicken. Local feed (control died) and control with probiotics are feed with self formulation (R0, and R1 – R3). Control diet based on the needs of broiler chickens by the National Research Council(NRC).Results showed that treatments did not give significant effect (P>0,05) percentage of carcass, body fat and edible offal. Giving probiotics biovet produce better carcass percentage compared with controls and other treatments.

The objective of the study was to evaluate the effect of two methods of processing Bambara Groundnut Offal (BGO), toasted and enzyme supplemented in broiler chicken diets on haematology and carcass characteristics of broiler finisher chicken. One hundred and eight (108) four- weeks- old unsexed commercial broiler chicks were divided into three groups (T10% T220% T320%) of 36 birds, each replicated three times with 12 birds per replicate in a completely randomized design and fed for 28 days. Haematological parameters were not significantly (p>0.05) affected. Result of carcass characteristics showed that live weight, eviscerated weight, dressed weight, back weight, drumstick weight, breast weight, thigh weight and caecum weight were significantly (p<0.05) affected. Birds fed enzyme supplemented BGO diets recorded higher weights compared with birds fed toasted BGO and the control diets. Other carcass characteristics such as wing weight, neck weight, head weight, shank weight and other internal organ characteristics were not significantly (p>0.05) affected.
 From the result, significant parameters have shown that birds fed bioenzyme supplemented BGO diets were superior to birds fed toasted BGO and the control diet. It is therefore recommended that 2g/kg bioenzyme supplemented BGO diet should be used at 20% BGO inclusion rate for finishing broiler chicken without adverse effect on the haematology and for increased carcass weight.

Introduction Eating is one of the most quintessential activities of human life. Because of this primacy, eating is, as food anthropologist Sidney Mintz has observed, “not merely a biological activity, but a vibrantly cultural activity as well” (48). This article posits that the current awareness of climate change in the Western world is animating such cultural activity as the Slow Food movement and is, as a result, stimulating what could be seen as an evolutionary change in popular foodways. Moreover, this paper suggests that, in line with modelling provided by the Slow Food example, an increased awareness of the connections of climate change to the social injustices of food production might better drive social change in such areas. This discussion begins by proposing that contemporary foodways—defined as “not only what is eaten by a particular group of people but also the variety of customs, beliefs and practices surrounding the production, preparation and presentation of food” (Davey 182)—are changing in the West in relation to current concerns about climate change. Such modification has a long history. Since long before the inception of modern Homo sapiens, natural climate change has been a crucial element driving hominidae evolution, both biologically and culturally in terms of social organisation and behaviours. Macroevolutionary theory suggests evolution can dramatically accelerate in response to rapid shifts in an organism’s environment, followed by slow to long periods of stasis once a new level of sustainability has been achieved (Gould and Eldredge). There is evidence that ancient climate change has also dramatically affected the rate and course of cultural evolution. Recent work suggests that the end of the last ice age drove the cultural innovation of animal and plant domestication in the Middle East (Zeder), not only due to warmer temperatures and increased rainfall, but also to a higher level of atmospheric carbon dioxide which made agriculture increasingly viable (McCorriston and Hole, cited in Zeder). Megadroughts during the Paleolithic might well have been stimulating factors behind the migration of hominid populations out of Africa and across Asia (Scholz et al). Thus, it is hardly surprising that modern anthropogenically induced global warming—in all its’ climate altering manifestations—may be driving a new wave of cultural change and even evolution in the West as we seek a sustainable homeostatic equilibrium with the environment of the future. In 1962, Rachel Carson’s Silent Spring exposed some of the threats that modern industrial agriculture poses to environmental sustainability. This prompted a public debate from which the modern environmental movement arose and, with it, an expanding awareness and attendant anxiety about the safety and nutritional quality of contemporary foods, especially those that are grown with chemical pesticides and fertilizers and/or are highly processed. This environmental consciousness led to some modification in eating habits, manifest by some embracing wholefood and vegetarian dietary regimes (or elements of them). Most recently, a widespread awareness of climate change has forced rapid change in contemporary Western foodways, while in other climate related areas of socio-political and economic significance such as energy production and usage, there is little evidence of real acceleration of change. Ongoing research into the effects of this expanding environmental consciousness continues in various disciplinary contexts such as geography (Eshel and Martin) and health (McMichael et al). In food studies, Vileisis has proposed that the 1970s environmental movement’s challenge to the polluting practices of industrial agri-food production, concurrent with the women’s movement (asserting women’s right to know about everything, including food production), has led to both cooks and eaters becoming increasingly knowledgeable about the links between agricultural production and consumer and environmental health, as well as the various social justice issues involved. As a direct result of such awareness, alternatives to the industrialised, global food system are now emerging (Kloppenberg et al.). The Slow Food (R)evolution The tenets of the Slow Food movement, now some two decades old, are today synergetic with the growing consternation about climate change. In 1983, Carlo Petrini formed the Italian non-profit food and wine association Arcigola and, in 1986, founded Slow Food as a response to the opening of a McDonalds in Rome. From these humble beginnings, which were then unashamedly positing a return to the food systems of the past, Slow Food has grown into a global organisation that has much more future focused objectives animating its challenges to the socio-cultural and environmental costs of industrial food. Slow Food does have some elements that could be classed as reactionary and, therefore, the opposite of evolutionary. In response to the increasing homogenisation of culinary habits around the world, for instance, Slow Food’s Foundation for Biodiversity has established the Ark of Taste, which expands upon the idea of a seed bank to preserve not only varieties of food but also local and artisanal culinary traditions. In this, the Ark aims to save foods and food products “threatened by industrial standardization, hygiene laws, the regulations of large-scale distribution and environmental damage” (SFFB). Slow Food International’s overarching goals and activities, however, extend far beyond the preservation of past foodways, extending to the sponsoring of events and activities that are attempting to create new cuisine narratives for contemporary consumers who have an appetite for such innovation. Such events as the Salone del Gusto (Salon of Taste) and Terra Madre (Mother Earth) held in Turin every two years, for example, while celebrating culinary traditions, also focus on contemporary artisanal foods and sustainable food production processes that incorporate the most current of agricultural knowledge and new technologies into this production. Attendees at these events are also driven by both an interest in tradition, and their own very current concerns with health, personal satisfaction and environmental sustainability, to change their consumer behavior through an expanded self-awareness of the consequences of their individual lifestyle choices. Such events have, in turn, inspired such events in other locations, moving Slow Food from local to global relevance, and affecting the intellectual evolution of foodway cultures far beyond its headquarters in Bra in Northern Italy. This includes in the developing world, where millions of farmers continue to follow many traditional agricultural practices by necessity. Slow Food Movement’s forward-looking values are codified in the International Commission on the Future of Food and Agriculture 2006 publication, Manifesto on the Future of Food. This calls for changes to the World Trade Organisation’s rules that promote the globalisation of agri-food production as a direct response to the “climate change [which] threatens to undermine the entire natural basis of ecologically benign agriculture and food preparation, bringing the likelihood of catastrophic outcomes in the near future” (ICFFA 8). It does not call, however, for a complete return to past methods. To further such foodway awareness and evolution, Petrini founded the University of Gastronomic Sciences at Slow Food’s headquarters in 2004. The university offers programs that are analogous with the Slow Food’s overall aim of forging sustainable partnerships between the best of old and new practice: to, in the organisation’s own words, “maintain an organic relationship between gastronomy and agricultural science” (UNISG). In 2004, Slow Food had over sixty thousand members in forty-five countries (Paxson 15), with major events now held each year in many of these countries and membership continuing to grow apace. One of the frequently cited successes of the Slow Food movement is in relation to the tomato. Until recently, supermarkets stocked only a few mass-produced hybrids. These cultivars were bred for their disease resistance, ease of handling, tolerance to artificial ripening techniques, and display consistency, rather than any culinary values such as taste, aroma, texture or variety. In contrast, the vine ripened, ‘farmer’s market’ tomato has become the symbol of an “eco-gastronomically” sustainable, local and humanistic system of food production (Jordan) which melds the best of the past practice with the most up-to-date knowledge regarding such farming matters as water conservation. Although the term ‘heirloom’ is widely used in relation to these tomatoes, there is a distinctively contemporary edge to the way they are produced and consumed (Jordan), and they are, along with other organic and local produce, increasingly available in even the largest supermarket chains. Instead of a wholesale embrace of the past, it is the connection to, and the maintenance of that connection with, the processes of production and, hence, to the environment as a whole, which is the animating premise of the Slow Food movement. ‘Slow’ thus creates a gestalt in which individuals integrate their lifestyles with all levels of the food production cycle and, hence to the environment and, importantly, the inherently related social justice issues. ‘Slow’ approaches emphasise how the accelerated pace of contemporary life has weakened these connections, while offering a path to the restoration of a sense of connectivity to the full cycle of life and its relation to place, nature and climate. In this, the Slow path demands that every consumer takes responsibility for all components of his/her existence—a responsibility that includes becoming cognisant of the full story behind each of the products that are consumed in that life. The Slow movement is not, however, a regime of abstention or self-denial. Instead, the changes in lifestyle necessary to support responsible sustainability, and the sensual and aesthetic pleasure inherent in such a lifestyle, exist in a mutually reinforcing relationship (Pietrykowski 2004). This positive feedback loop enhances the potential for promoting real and long-term evolution in social and cultural behaviour. Indeed, the Slow zeitgeist now informs many areas of contemporary culture, with Slow Travel, Homes, Design, Management, Leadership and Education, and even Slow Email, Exercise, Shopping and Sex attracting adherents. Mainstreaming Concern with Ethical Food Production The role of the media in “forming our consciousness—what we think, how we think, and what we think about” (Cunningham and Turner 12)—is self-evident. It is, therefore, revealing in relation to the above outlined changes that even the most functional cookbooks and cookery magazines (those dedicated to practical information such as recipes and instructional technique) in Western countries such as the USA, UK and Australian are increasingly reflecting and promoting an awareness of ethical food production as part of this cultural change in food habits. While such texts have largely been considered as useful but socio-politically relatively banal publications, they are beginning to be recognised as a valid source of historical and cultural information (Nussel). Cookbooks and cookery magazines commonly include discussion of a surprising range of issues around food production and consumption including sustainable and ethical agricultural methods, biodiversity, genetic modification and food miles. In this context, they indicate how rapidly the recent evolution of foodways has been absorbed into mainstream practice. Much of such food related media content is, at the same time, closely identified with celebrity mass marketing and embodied in the television chef with his or her range of branded products including their syndicated articles and cookbooks. This commercial symbiosis makes each such cuisine-related article in a food or women’s magazine or cookbook, in essence, an advertorial for a celebrity chef and their named products. Yet, at the same time, a number of these mass media food celebrities are raising public discussion that is leading to consequent action around important issues linked to climate change, social justice and the environment. An example is Jamie Oliver’s efforts to influence public behaviour and government policy, a number of which have gained considerable traction. Oliver’s 2004 exposure of the poor quality of school lunches in Britain (see Jamie’s School Dinners), for instance, caused public outrage and pressured the British government to commit considerable extra funding to these programs. A recent study by Essex University has, moreover, found that the academic performance of 11-year-old pupils eating Oliver’s meals improved, while absenteeism fell by 15 per cent (Khan). Oliver’s exposé of the conditions of battery raised hens in 2007 and 2008 (see Fowl Dinners) resulted in increased sales of free-range poultry, decreased sales of factory-farmed chickens across the UK, and complaints that free-range chicken sales were limited by supply. Oliver encouraged viewers to lobby their local councils, and as a result, a number banned battery hen eggs from schools, care homes, town halls and workplace cafeterias (see, for example, LDP). The popular penetration of these ideas needs to be understood in a historical context where industrialised poultry farming has been an issue in Britain since at least 1848 when it was one of the contributing factors to the establishment of the RSPCA (Freeman). A century after Upton Sinclair’s The Jungle (published in 1906) exposed the realities of the slaughterhouse, and several decades since Peter Singer’s landmark Animal Liberation (1975) and Tom Regan’s The Case for Animal Rights (1983) posited the immorality of the mistreatment of animals in food production, it could be suggested that Al Gore’s film An Inconvenient Truth (released in 2006) added considerably to the recent concern regarding the ethics of industrial agriculture. Consciousness-raising bestselling books such as Jim Mason and Peter Singer’s The Ethics of What We Eat and Michael Pollan’s The Omnivore’s Dilemma (both published in 2006), do indeed ‘close the loop’ in this way in their discussions, by concluding that intensive food production methods used since the 1950s are not only inhumane and damage public health, but are also damaging an environment under pressure from climate change. In comparison, the use of forced labour and human trafficking in food production has attracted far less mainstream media, celebrity or public attention. It could be posited that this is, in part, because no direct relationship to the environment and climate change and, therefore, direct link to our own existence in the West, has been popularised. Kevin Bales, who has been described as a modern abolitionist, estimates that there are currently more than 27 million people living in conditions of slavery and exploitation against their wills—twice as many as during the 350-year long trans-Atlantic slave trade. Bales also chillingly reveals that, worldwide, the number of slaves is increasing, with contemporary individuals so inexpensive to purchase in relation to the value of their production that they are disposable once the slaveholder has used them. Alongside sex slavery, many other prevalent examples of contemporary slavery are concerned with food production (Weissbrodt et al; Miers). Bales and Soodalter, for example, describe how across Asia and Africa, adults and children are enslaved to catch and process fish and shellfish for both human consumption and cat food. Other campaigners have similarly exposed how the cocoa in chocolate is largely produced by child slave labour on the Ivory Coast (Chalke; Off), and how considerable amounts of exported sugar, cereals and other crops are slave-produced in certain countries. In 2003, some 32 per cent of US shoppers identified themselves as LOHAS “lifestyles of health and sustainability” consumers, who were, they said, willing to spend more for products that reflected not only ecological, but also social justice responsibility (McLaughlin). Research also confirms that “the pursuit of social objectives … can in fact furnish an organization with the competitive resources to develop effective marketing strategies”, with Doherty and Meehan showing how “social and ethical credibility” are now viable bases of differentiation and competitive positioning in mainstream consumer markets (311, 303). In line with this recognition, Fair Trade Certified goods are now available in British, European, US and, to a lesser extent, Australian supermarkets, and a number of global chains including Dunkin’ Donuts, McDonalds, Starbucks and Virgin airlines utilise Fair Trade coffee and teas in all, or parts of, their operations. Fair Trade Certification indicates that farmers receive a higher than commodity price for their products, workers have the right to organise, men and women receive equal wages, and no child labour is utilised in the production process (McLaughlin). Yet, despite some Western consumers reporting such issues having an impact upon their purchasing decisions, social justice has not become a significant issue of concern for most. The popular cookery publications discussed above devote little space to Fair Trade product marketing, much of which is confined to supermarket-produced adverzines promoting the Fair Trade products they stock, and international celebrity chefs have yet to focus attention on this issue. In Australia, discussion of contemporary slavery in the press is sparse, having surfaced in 2000-2001, prompted by UNICEF campaigns against child labour, and in 2007 and 2008 with the visit of a series of high profile anti-slavery campaigners (including Bales) to the region. The public awareness of food produced by forced labour and the troubling issue of human enslavement in general is still far below the level that climate change and ecological issues have achieved thus far in driving foodway evolution. This may change, however, if a ‘Slow’-inflected connection can be made between Western lifestyles and the plight of peoples hidden from our daily existence, but contributing daily to them. Concluding Remarks At this time of accelerating techno-cultural evolution, due in part to the pressures of climate change, it is the creative potential that human conscious awareness brings to bear on these challenges that is most valuable. Today, as in the caves at Lascaux, humanity is evolving new images and narratives to provide rational solutions to emergent challenges. As an example of this, new foodways and ways of thinking about them are beginning to evolve in response to the perceived problems of climate change. The current conscious transformation of food habits by some in the West might be, therefore, in James Lovelock’s terms, a moment of “revolutionary punctuation” (178), whereby rapid cultural adaption is being induced by the growing public awareness of impending crisis. It remains to be seen whether other urgent human problems can be similarly and creatively embraced, and whether this trend can spread to offer global solutions to them.
