Abstract:
The article describes that domestic feed products cannot always compete with high quality products of foreign firms. However, the use of imported feed leads to a significant increase in their value and, as a consequence, to an increase in the cost price of the final product. It is established that for the normal development and realization of productivity, turkeys should receive quality and balanced for all indicators of compound feed. Therefore, the task was to develop recipes for turkeys using high quality domestic raw materials. The necessity to determine the complete components characteristics of compound feeds for the finished products production, which meets the requirements of regulatory documents and the consumer, has been proved. There are many indicators and factors that are not taken into account when calculating recipes, but significantly affect the compound feed quality. We have developed compound feed recipes for heavy type turkeys aged 1…4 weeks, 5…13 weeks, 14…17 weeks, 18…30 weeks and over 31 weeks using the “Korm Optima Expert” software complex. The program incorporates the principle of calculating recipes at minimum cost, taking into account the restrictions on the input of each component and the nutrition of the finished product using linear programming by formulas. The expediency of replacing soybean meal in poultry feed due to its high cost for cheaper protein components is substantiated. In order to reduce the cost of compound feed, we have proposed the optimal composition of protein feed additive (PFA) for replacement soybean meal in feed recipes. On the basis of the developed recipes of compound feeds for heavy type turkeys we calculated similar recipes of compound feeds with replacement of soybean meal for PFA in their composition according to the norms of its introduction The quality indicators of finished products are in compliance with the minimum nutritional requirements of compound feeds for heavy type turkeys of a given age. The cost of compound feeds with PFA is much lower than similar with soybean meal. We determined the annual feed consumption of turkeys by growing periods based on the daily feed intake and the duration of each fattening period.

Abstract:
The article describes that there is a problem of providing the population of the planet with a complete protein in the world today. It is proved that its lack can lead to significant pathologies. This issue becomes very acute with the rapid increase in the number of people on Earth. In this situation the challenge is complicated for compound feed producers because it is necessary to provide protein feeds to farm animals and poultry to meet people's needs for animal protein products. However, feed manufacturers should not use protein raw materials that can be consumed as food. Based on cooperation with compound feed producers, the task of finding alternative sources of protein raw materials, preferably of vegetable origin, is set. The optimal composition of protein feed additive (PFA) for soybean meal replacement in compound feeds for farm animals and poultry has been developed. PFA can be manufactured at a feed mill with portion technology by weighing portions of components and mixing in a paddle periodic action mixer. PFA can be used as a part of compound feeds for poultry farms and livestock complexes, feed concentrates for poultry and livestock farms, feed mills with advanced technology, inter-farm or mini-feed mills. We have developed compound feed recipes for heavy type turkeys using PFA to determine the cost-effectiveness of using PFA in compound feed. Turkeys have been chosen as a poultry because they are the most demanding birds to the quality and quantity of protein in the ration. The experimental samples of PFA were made in accordance with the developed recipes. We determined their physical properties and chemical composition. The PFA experimental samples match the quality of soybean meal according to the physical properties and chemical composition. In accordance with the developed recipes of mixed feeds for heavy type turkeys experimental samples of starter and grower feeds were made. Research of the physical properties and chemical composition of compound feeds has shown that the replacement of soybean meal with PFA in their composition does not affect the nutritional value and technological properties of the final product.

Abstract:
Fatty acid compositions of the lipids extracted from various fish feeds (Eco-float, Blue-crown, Uncle - frances, Triton, Stretting, Crown, Jik, Shaldac, Solace, Coppens, Vital, Local sinking, Local feed, Aqualis and Local floating) vended in Lagos State were determined. These feeds were designated as Feeds A to O respectively. Feed samples were procured from major fish feed markets and fish farms within Lagos metropolis and transported to the laboratory for analysis. Methylation was carried out after oil extraction to convert the fats to their methyl esters and the fatty acids methyl esters (FAME) were separated by gas chromatography. Fatty acids were analysed using a HP Agilent 5890 system gas chromatograph equipped with SP-2330 and a flame ionization detector (FID). Results revealed that the highest values for polyunsaturated fatty acid (PUFA), saturated fatty acid (SFA) and ∑n-3 unsaturated fatty acid (HUFA) were 58.26% in feed F, 38.7% in feed M and 3.59% in feed N respectively while the lowest values for PUFA (19.76%) and SFA (15.53%) were recorded in feeds M and J respectively. The results also showed that, though feed samples were high in monounsaturated fatty acid (MUFA) (55- 22%) and PUFA (58-19%), they were low in n-3 HUFA {eicosapentaenoic acids (EPA, 20:5n-3) and docosahexaenoic acids (DHA, 22:6n-3)} with the values of 0.3-3%. The shortfall in EPA and DHA of these feeds may imply that fish fed these feeds may be nutritionally deficient in these fatty acid compositions. Thus, further manipulation may be needed to improve the value of these feeds in terms of EPA and DHA. Keywords: Fish feeds, n-3 HUFA, n-6 HUFA, Nutritional quality, aquaculture

Abstract:
When compiling diets for productive animals, one of the indicators taken into account is the cationanion balance, which is calculated based on the content of sodium and potassium cations and sulfate and chloride anions. The cationic-anionic composition of feed is very diverse. The lack or excess of one or another cation or anion in feed can lead to disruption of metabolic processes and various diseases of non-infectious etiology.The aim of the work was to quantify and analyze the cationanion composition of feed for productive animals by capillary electrophoresis.The research was carried out in the conditions of the educational and research center for the examination of food and animal feed of the St. Petersburg State University of Veterinary Medicine. 76 samples of various feeds for productive animals were used as research materials: 19 samples of grass flour, cake, mixed feeds for cattle.The study of the cationic composition of the studied feed samples was carried out, guided by the methodology M 04-65-2010 «Feed, compound feed and raw materials for their production. The method of measuring the mass fraction of ammonium, potassium, sodium, magnesium and calcium cations by capillary electrophoresis using the capillary electrophoresis system «Kapel», and anionic composition – according to the method M 04 -73-2011 «Feed, compound feed and raw materials for their production. The method of measuring the mass fraction of water-soluble forms of chloride, sulfate, nitrate and phosphate ions by capillary electrophoresis using the capillary electrophoresis system «Kapel» (GC «LUMEX»).Thus, analyzing the results obtained, it was found that in all samples of feed for productive animals, the mass fraction of cations and anions varied depending on the type of cation or anion and feed.Determination of the cationic-anionic composition of feed is a necessary condition for the formation of a full-fledged diet that provides the body of productive animals with nutrients, which is especially important in modern conditions of intensification of animal husbandry and agricultural development.

Abstract:
Forty pigs (twenty males and twenty females) were weaned at 4 weeks of age into individual cages, and their weights and feed intakes measured daily. From weaning to 16 kg live weight they were given free access to a feed with either 134 (L) or 278 (H) g crude protein (nitrogen × 6.25)/kg fresh weight. During this period pigs on feed L grew at a slower rate and converted feed less efficiently than pigs on feed H. At 16 kg live weight they were introduced to a 6 d period of feeding when, on succesive days, they were given feeds L, H, L, H, L and H (if previously fed on L) or feeds H, L, H, L, H and L (if previously fed on H). For pigs previously given access to feed L the live-weight gain was 1061 v. 575 g/d on the days when H or L was given; the feed intake was 1078 v. 1027 g/d respectively. For pigs previously given access to feed H, the live-weight gain was 655 v. 610 g/d and the feed intake 844 v. 1071 g/d on the days when H or L were given. The interactions between the feed given previously and the feed given for the 3 d of the subsequent 6 d period were highly significant for both live-weight and feed intake. These rapid changes in feed intake and growth rate suggest that the metabolism of young pigs is extremely flexible, with a rapid rate of response to a change in the protein content of their feed.

Abstract:
Proximate composition and microbial quality of three aquarium fish feeds commonly found in Bangladesh were collected from fish feed market of Dhaka city. Significantly higher moisture content (2.12 ± 0.06%) was found in Super NovaTM fish feed while similar moisture content was detected in other two feeds (p<0.05). On the other hand ash content detected in OptimumTM and Osaka 2000TM aquarium fish feed was significantly higher than that of Super NovaTM (10.67±0.19%) (p<0.05).Protein content found in OptimumTM (42.21 ± 0.12%) was significantly higher than that of Osaka 2000TM and Super NovaTM (p<0.05). However, similar lipid content was found in OptimumTM (1.06 ± 0.03%) and Super NovaTM (1.13 ± 0.01%) aquarium fish feed which were significantly higher than that of Osaka 2000TM (p<0.05). The Escherichia coli and Staphylococcus aureus were found in all feeds. However Vibrio sp was not found in any feed. Total bacterial count was significantly higher in Osaka 2000TM feed than that of others (P<0.05). However S. aureus was significantly higher in Super NovaTM than that of others while E. coli count was significantly higher in OptimumTM fish feed than that of others (p<0.05). Nutritional quality of the aquarium fish feed was qualified to some extent to meet the minimum requirement of the aquarium fish while microbial quality indicates some degrees of deterioration which may cause diseases of the aquarium fishes. Thus proper storage condition, hygienic handling and processing should be maintained to prevent the microbial contamination in aquarium fish feeds. There should be a monitoring cell from the government to assess the quality of this expensive imported feeds for aquarist.Bangladesh J. Zool. 42(2): 283-294, 2014

Abstract:
Objectives of this study were to determine if variation in energy expenditures contributed to differences in feed efficiency between low and high RFI steers. Nine steers with the lowest and highest residual feed intakes (RFI) were selected from 169 Braunvieh-sired crossbred steers that were individually fed a pelleted roughage-based diet for 77 d. Following the RFI measurement period, heat production (HP) measurements were obtained using indirect calorimetry while steers were fed the same roughage diet (RD) and on a high-concentrate diet (CD). Linear regression analyses of log HP or retained energy on ME intake were used to determine energy partitioning. Motion and lying activity were measured concurrently with HP on the RD and CD. During the RFI measurement period, low RFI steers had lower (P < 0.01) RFI (-1.7 vs. 1.6 ± 0.17 kg/d), DMI (7.7 vs. 10.2 ± 0.42 kg/d) and feed:gain ratio (F:G; 7.2 vs. 10.6 ± 0.60), but similar final BW and ADG compared to high RFI steers. However, there were smaller differences in DMI (8.4 vs. 9.7 ± 0.38 kg/d; P < 0.05; 7.56 vs. 8.16 ± 0.31; P = 0.19) and F:G (10.0 vs. 10.9 ± 0.40; P = 0.36; 6.5 vs. 7.5 ± 0.30; P < 0.05) between low and high RFI steers, on the RD and CD, respectively. ME for maintenance (MEm; kg .75 d–1) and the partial efficiencies of ME used for maintenance and gain were similar for low and high RFI steers. Likewise, no differences were found in fasting HP or fed HP. Motion activity was lower (P < 0.05) for low RFI steers compared to high RFI steers during fasting HP. Covariate analysis of HP at the same activity level yielded similar results. At slaughter, weights of lung and trachea (P < 0.05), spleen (P < 0.05) and adrenal gland (P = 0.07) were higher for low RFI cattle. The lack of differences in energy partitioning between divergent RFI steers may have been the result of alterations in feeding behavior or stress imposed by adapting steers to calorimetry chambers.

Abstract:
An investigation into the effects of feed composition on lactational performance was carried out using rats and cows. A graphical representation of the feed as a triangle was used to aid the interpretation of results. The first rat experiment showed that, on high protein feeds, the lactational performance of rats is not depressed when offered feeds of very low carbohydrate content. This was substantiated by the other rat experiments. When carbohydrate in the feed was replaced by fat at low protein content (rat experiment 2) there was a large depression in lactational performance, effectively a cessation of mild production. The interaction between the three feed components protein, carbohydrate and fat was highly significant. The hypothesis that maternal heat production was limiting food intake was advanced. The third rat experiment used feeds whose composition was marginal in relation to lactational success. The feeds also allowed comparison between feeds of constant nutrient:energy ratio. The results of this experiment indicated that there is an extremely abrupt threshold in feed composition for adequate lactation. This effect could not be attributed to any one nutrient:energy ratio. This experiment also showed the importance of maternal body reserves in support of lactation. A model was developed to explore the hypothesis that maternal heat production was limiting performance, however this model failed. An experiment using sheep was conducted in order to permit prediction of the volatile fatty acid proportions arising from a range of feeds. This experiment was designed to allow application of the rat work to dairy cows. A dairy cow trial was conducted to compare different feed types and feeding levels. The results of this trial showed no effect of feed type on lactational performance. A linear relationship between food intake and level of milk production was found. This included an effect of feeding level on rate of decline in milk yield. All these findings are discussed in detail.

Abstract:
In this study the stability and nutrient removal performance of aerobic granules under variable operating pH and variable growth medium was investigated. The results indicated that alkaline pH (pH=9) inhibited nitrogen and phosphorus removal. Moreover, high pH induced granules breakage and resulted in an increased biomass concentration in the effluent. On the other hand, acidic pH (pH=6) did not have significant impacts on stability and nutrient removal efficiency of granules. Changing the growth medium from acetate-based wastewater to municipal wastewater resulted in loss of biological phosphorus removal while ammonium and COD removal stayed the same. The granules disintegrated during the first two weeks after changing the feed; re-granulation of the biomass was observed after the acclimation of bacteria to the new growth medium. However, the granules breakage did not exert significant impact on settling property of biomass.

Abstract:
Understanding the central nervous systems role in appetite regulation is crucial to cure the obesity epidemic, which is more prevalent than any disease in the United States. Central appetite regulators, known as neuropeptides, are pivotal in understanding appetite regulation. Neuropeptide Y (NPY), a 36 amino acid peptide, plays a major role in regulating the hunger signals from the brain. In all vertebrates studied, it is a strong orexigenic neurotransmitter located throughout multiple nuclei of the hypothalamus. Peripheral hormones associated with hunger are able to activate NPY neurons in the arcuate nucleus, which leads to a cascade of events that activate orexigenic neurons throughout the hypothalamus. Although extensive research has gone into understanding the role of NPY in appetite regulation, the effects of macronutrient composition of diets on NPY function have not been elucidated in non-mammalian species. This research investigates how food intake is affected by dietary macronutrient composition in broiler type chickens that are fed three varying macronutrient diets: high carbohydrate (22% CP, 3000kcal/kg) a broiler starter diet, high fat (60% ME from lard), high protein 30%CP). All diets were formulated to be isocaloric. When chicks are fed the high fat diet central NPY administration has a greater effect on feed intake compared to both the basal and high protein diet. Regardless of what diet the chick is fed from hatch, if they are switched to one of the other two diets post central administration of NPY the high fat diet stimulated feed intake for the longest duration. Although, NPY had the strongest orexigenic effect on chicks fed the high fat diet, in a choice diet situation broiler chicks chose the high protein diet, independent of central NPY administration.

A split plot design was employed (3 genders = intact males, castrated males, and females; 3 levels of feed restriction = 0% [ad libitum], 25%, and 50%). Groups of 3 goat kids was formed by gender (each goat eating one level of feed restriction); goats of each group were slaughtered when animals fed ad libitum reached 30 kg BW (Experiment 1) and 45 kg (Experiment 2). Blood samples were evaluate glucose, total protein, albumin, urea, creatinine, cholesterol, non-esterified fatty acid, beta-hydroxybutyrate, aspartate aminotransferase, gamma glutamyltransferase, creatine kinase, triiodothyronine, thyroxine, and insulin-like growth factor. Females had greater retention of body fat (% empty BW) regardless the level of feed restriction (P<0.001). Both gender and feed restriction affected energetic and proteic metabolism of goats (P< 0.05). Females from 15 to 30 kg BW changed their glycolytic metabolism to retain fat deposition even when subjected to feed restriction, while males mainly changed their protein metabolism to retain protein synthesis, and were less affected by feed restr...

Abstract:
This study investigated the hypothesis that cattle fed to produce a lean carcass during a winter restriction period will subsequently grow faster and remain leaner than fatter steers during the summer, exploiting cheap grazed grass. Three studies were carried out; in the first study steers were restricted at three levels of growth (300, 600 and 900 g/day) during winter and turned out to graze grass during summer. At each level of growth during winter steers were fed on one of two diets aimed at producing steers of either a lean or fat carcass composition. At the end of the winter restriction period differences in lean composition were observed at the 300 and 600 g/day growth rates. Steers were slaughtered when they attained the target slaughter weight at the end of summer; but there was no difference between treatments in meat quality characteristics or fat composition. Liveweight gain during the summer period was inversely correlated to winter liveweight gain. Two further studies were carried out to assess the effect of altering carcass composition during winter, fed to a predicted growth rate of 600g/day to investigate the underlying physiological and endocrinological mechanism regulating the growth characteristics. In the first study at the end of winter steers that were fatter had higher glucose and insulin concentrations. No differences between diet treatments were detected in muscle protein synthesis or breakdown. At the end of the winter in the second experiment there were no differences in carcass composition, metabolite or hormone profiles between treatments. For both studies, at the end of summer, steers on different dietary treatments had similar carcass compositions and metabolic parameters. It was concluded that by altering the diet of steers during a winter restriction period the composition of carcass gain can be manipulated. Since steers altered the deposition of carcass protein and fat during the subsequent summer period at grass resulting in similar body compositions at slaughter it was deduced the that composition of steers at the end of winter remains unimportant. Reductions in beef production costs may be attained by restricting the growth rates during winter when commercial feeds are expensive.

Abstract:
The research was carried out in the field at the Central experimental base of the Federal Williams Research Center. The object of research was 13 samples of timothy-grass. Samples were sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 2nd and 3rd year of life. Statistical processing of the research results indicates a low level of variation. The sample № 414 stood out high content of raw protein and raw fat. Two significant correlations were found (between the content of phosphorus and potassium, as well as between crude fiber and crude ash). Analysis of remoteness and kinship between samples showed the presence of 5 clusters (genetically different quality groups), which can be used for breeding for combinational ability and fixing of breeding-valuable features and properties.

Abstract:
On average, for 71–75 years, the yield of long-term hayfield in the variant without fertilizers was 35.4 c/ha of dry matter, with the application of N180P45K90 — 81.8 c/ha of dry matter. The bulk of the yield is formed in the first cut — 54–76%. Over the years of research, against the background of low doses of fertilizers, the herbage was reshaped into a grassland-grass-legume-forb with the dominance of the intruded species of red fescue — 27.6–74.0%, against the background of the introduction of N120–180PK into a hay-grass-forb with dominance of foxtail meadow brome 27.2–58.6% and awnless brome 42.1–83.5%. Higher feed quality: 10.5–13.59% crude protein, 26.54–29.14% crude fibre, 9.36–10.03 MJ metabolic energy and 0.72–0.80 feed units in 1 kg of dry matter was noted in the first cut.
