Full textAbstract:
Abstract Organic products have been growing in popularity in the consumer market, often without evidence to support potential benefits. Many organic products promise better results than conventional products, yet research examining the use of organic products as a feedstuff in caprine diets is lacking. Additionally, the cost of organic feedstuff is much greater when compared to conventional. Reproductive success of an animal has a direct correlation with nutrition throughout pregnancy and could be impacted by organic products. Thus, potential benefits of increase of reproductive health could outweigh the initial cost of organic feedstuffs. The objective of the current study was to determine differences in dystocia occurrence between caprine dams fed conventional and organic feedstuffs in the last 6 wk of gestation. Eight gestating Nubian does (n = 4) ranging from 1 to 5 yr of age with initial BW between 45.4 and 68.5 kg were separated into two treatment groups based on BCS utilizing the American Dairy Goat Association’s BCS 1 to 5 scale. Treatment A was fed a conventional diet including 14% CP concentrate, mineral supplementation, and molasses. Treatment B was fed an equivalent USDA certified organic concentrate, mineral supplement and molasses. Dams were fed 0.907kg/d/45.4kg of BW of concentrate and mineral supplement at 0.012kg/d/45.4kg of BW in individual feeding stocks at 0630 and 1730 in the last 6 wk of gestation. All Dams were provided ad libitum to hay and water. During parturition, dystocia was defined as requiring obstetrical assistance at any point during kidding. Differences in dystocia rate between conventional and organic groups were analyzed by independent T-Test at P < 0.05. As expected, no differences were observed between organic and conventional treatment groups (p = 0.28). As a result, the increased priced of organic feedstuff was not justified for feeding over conventional products.

Full textAbstract:
The search for balanced diets, which may elicit improved growth of fish, requires appropriate selection of available protein sources. This study aims at clustering feedstuffs according to amino acid profile, determining which ones show essential amino acids (EAA) profiles closer to the ideal dietary amino acids requirements of Nile tilapia (Oreochromis niloticus), and studying the relationship among amino acids feedstuffs groups. Tabled data on EAA more cystine and tyrosine, in relation to lysine contents, of 40 feedstuffs ordinarily used to formulate fish diets were studied. Feedstuffs were grouped according to amino acids profile by cluster analysis of Euclidean distances. The principal components analysis was used to determine the relationship among amino acids in each feedstuff group. Three groups of ingredients were parted and two ingredients, low tannin sorghum and corn gluten meal 60%, did not go with any group. Dietary amino acids requirements of Nile tilapia were similar to the amino acid profile of 22 feedstuffs. The principal component analysis explained with three principal components more than 75% of total variance of amino acids in three feedstuff groups. Therefore, until additional, detailed information on amino acids availability of different ingredients is consolidated, total amino acids profiles will continue to be important information to select and use conventional or surrogate ingredients for formulating and processing feeds for tilapia.

Full textAbstract:
Feed supply has remained a major constraint in animal production due to an ever-increasing cost of conventional feedstuff occasioned by the competition between man and animals for cereal grains. There is need to harness the potential of the numerous agro-industrial by-products and the so-called wastes as part of replacing them for expensive feedstuffs. This necessitated for the utilization of kenaf grains and leaf in the diet of micro–livestock. The cost of conventional feedstuffs coupled with high demand for grains for human consumption has stimulated interest in the use of non-conventional, readily available, and cheaper source of feedstuffs. Use of kenaf by-product in other livestock with an impressive result has been recorded without any deleterious effect on the experimental animals. Kenaf is an annual or biennial herbaceous short-lived plant belongs to family malvaceae and is usually considered as a fiber crop, primarily used for rope, twine, coarse cloth and paper. Hence, kenaf grains and leaf could be used as alternative feed resource for micro-livestock.

This study examines effects of privately producing layers mash by including such non-conventional feedstuff as cassava, brewers dried grain, etc on the productivity, cost and profit of poultry (eggs) farms. Primary data was collected from three categories of farms -12 "conventional feedstuff users" (CFU), 24 "non-conventional feedstuff users" (NCFU) and 10 Animal Care concentrate users" (ACCU) found in a sample survey of 46 private feed using farms in Egbeda and Lagelu Local Government area of Ibadan. Estimates of their production, total variable cost and profit functions obtained by ordinary least squares as well as analyses of variance conducted on their production and cost statistics revealed that no sufficient evidence exists to suggest that productivity levels differ across the three categories of farms, but NCFU significantly lower average cost and more profits per trm of eggs produced than the CFU. No sufficient evidence, however, exists to suggest that ACCU had any significantly different cost or profit per tray of eggs produced from those of CFU.

Full textAbstract:
In Africa, Nigeria offers the largest market for fisheries products. Fish culture is gaining importance in Nigeria as locally available raw materials such as yam, plantain, banana, cowpeas, mucuna, maize, cassava, millet, sorghum, groundnut, sunhemp seed and brewery wastes are considered as potential materials for fish feed. Non–conventional feeds are locally available feedstuff which are not standardized and the usage is not widely-spread. In most cases, they are not consumed by man. Sadly, Nigerian economy had depended on imported feedstuffs to supplement the domestic conventional feedstuffs, however, the country is currently looking into a way of improving local feedstuffs production to minimize importation. In Fisheries and Aquaculture, there are many contemporary issues but this paper focuses on the use of non–conventional feed ingredients like Typha flour in fish feed. Several parts of Typha are edible including the rhizome. Research has shown that the plant is rich in energy, carbohydrates, sugars, dietary fiber, protein, vitamins, minerals and water. The competition for the conventional feed ingredients for human and animal consumption has resulted in significant price escalations hence the need for on-going research on alternativeingredients for use in aquafeed. Thus, great attention is given to the production of effective and cheap feed that will benefit fish farmers in Africa because fish feed is very important. Despite the fact that several studies have been done in Nigeria to replace fishmeal with other proteins of plant & animal origin but the results have been range from poor to very good in terms of fish growth and fish conversion efficiency.

Full textAbstract:
Abstract Corn, peanut meal, and soybean meal samples were either untreated or oxidized with performic acid before hydrolysis; the amino acids were determined by cation exchange high performance liquid chromatography (LC) and conventional cation exchange LC using an amino acid analyzer (AAA). Reproducibility of each procedure was assessed by repeated injections of the same calibration standard solution over a period of several days. LC data were more precise with regard to coefficients of variation for amino acid retention times, but were more variable with regard to peak areas. Although some significant differences between methods were noted, feedstuff amino acid values obtained by LC and AAA compared very well. The only consistent differences observed within each feedstuff were that Phe and Tyr values were significantly lower when analyzed by LC compared with AAA. Results of this study suggest that modular LC instrumentation can be used to accurately and reproducibly analyze amino acids in feedstuff hydrolysates. Advantages of using ninhydrin derivatization for feedstuff analysis, as opposed to using o-phthalaldehyde or dansyl chloride, are discussed

Full textAbstract:
Yellow mealworm meal (MWM) as a protein feedstuff in the broiler diet was investigated based on the growth performance, hematological characteristics, carcass, and meat quality of broiler chicks. A total of 700 one-day-old Ross 308 male broiler chicks were assigned to five dietary MWM treatments containing 0%, 2%, 4%, and 8% dried MWM or 10.48% fresh mealworm (corresponding to 4% dried MWM). For each treatment, there were seven pens with 20 chicks each. The nutritional profile of dried MWM is comparable to all conventional protein feedstuffs. MWM significantly increased BW and ADG (linear and quadratic, p < 0.05), and FCR was best at 4% MWM inclusion level (quadratic, p < 0.10) for broiler chicks during the starter phase. The predicted MWM levels for optimal starter BW and ADG were 4.13% and 3.84%. Hematological characteristics of broiler chicks fed on the MWM diet did not differ or showed small change within the physiological range. A fresh 10.48% mealworm diet significantly reduced the blood LZM for the grower. Broiler Chicks fed on fresh 10.48% mealworm had a significantly reduced abdominal fat percentage compared to the 4% dried MWM counterparts. MWM did not significantly affect meat quality. Taken together, MWM inclusion in broiler diet is acceptable as a protein feedstuff, and a 4% level could stimulate early growth in the starter phase.

Full textAbstract:
The steady increase in the price of protein feed ingredients and the retraction of antibiotics from diets has encouraged nutritionists to search the alternatives for protein source and functional feedstuffs that can substitute the role of antibiotic growth promoters in poultry production. With crude protein of 24-30%, in vitro protein digestibility of 80% and proportion of essential amino acids of 47%, seed from ripe papaya may be exploited as the alternative protein feed ingredient for poultry. Moreover, the growth promoting effect, antimicrobial and antiparasitic activities, and immunomodulatory and antioxidative activities may confirm the potential of papaya seed as a functional feedstuff that could replace the role of antibiotic growth promoters for poultry. The in-depth study is needed to further elucidate the functionalities of papaya seed on poultry. This review provides the updates on the nutritional contents of papaya seed, the potential of papaya seed as an alternative to conventional protein-rich ingredient, the growth-promoting effect of feeding papaya seed, the antimicrobial and antiparasitic activities of papaya seed, antioxidative activities of papaya seed, and the immunomodulatory activity of papaya seed on poultry.

Czech Journal of Animal Science 56, No. 10 (2011): 451–64. http://dx.doi.org/10.17221/3238-cjas.
Full textAbstract:
Three digestibility experiments were conducted to evaluate the potential of determination of apparent ileal digestibilities (AID) of crude protein (CP) and amino acids (AA) by the mobile nylon bag technique (MNBT) using 21 feedstuffs and three mixed diets. In two conventional digestibility experiments (Exp. 1 and 2), AID were determined using in total 10 barrows (BW 35 kg) fitted with simple T-cannulas at the terminal ileum. For the MNBT studies, four pigs were fitted with a simple T-cannula at the proximal duodenum and a Post-Valve T-Caecum (PVTC) cannula at the terminal ileum. The MNBT studies included the feedstuffs (n = 10) from Exp. 1 and 2 as well as 14 further feedstuffs and mixed diets in which AID coefficients had been determined in previous trials. For each feedstuff 60 nylon bags were used. In vitro digestion of the bags was carried out in pepsin-HCl solution with 450 IU pepsin/l at pH 2.0 and 37&deg;C for 4 h. In the 28-day in vivo experiment, 15 nylon bags per pig and day were inserted through the duodenal cannula and collected through the PVTC cannula after passage through the small intestine. Coefficients of AID were calculated based on the disappearance of CP and AA from the nylon bags during the in vitro and in vivo phase. In comparison with AID determined by the conventional method, AID of CP was on average 2.4% lower, whereas AID of lysine was on average 8.5% higher when determined by the MNBT. There was no significant (P &gt; 0.05) correlation between AID coefficients of CP and AA determined by the conventional method and the MNBT, when all feedstuffs were taken into account. However, in cereals (n = 11), the correlation between AID coefficients determined by both methods was significant (P &lt; 0.05) for CP (r = 0.61) and some AA (r ranging between 0.62 and 0.72). In conclusion, the potential of the MNBT to determine AID of CP and AA is rather limited. Differences in coefficients of AID of CP and AA were attributed to several factors such as diffusion of sample particles or endogenous protein through the nylon bags as well as to the presence of anti-nutritional factors (e.g. in legume seeds and oilseed meals).

Full textAbstract:
Cassava pulp is a by-product from the starch industry which was used as cheap alternative livestock feed. However, it has a limitation of low protein and high fibre to use in monogastric animals. Nutrient improvement of cassava pulp usually employs the use of inorganic nitrogen fertilizer. Here we demonstrated the use of chicken manure as an organic nitrogen source in compensation for the inorganic nitrogen. This research aimed to investigate the efficacy of cassava pulp fermented by dried chicken manure with yeast (CPCM) in a maize-soybean-based diets of pigs on nutrients digestibility, haematological parameters, and growth performance of barrow pigs as alternative energy feed. The results showed that the CPCM had crude protein increase from 1.99% of the plain cassava pulp to 8.54% (p < 0.05), while the crude fibre of CPCM decreased from 15.63 to 13.85%. Investigation of the diets containing CPCM as a replacement of maize at 4 levels (0%, 5%, 10%, and 15%) in twenty-four castrated male pigs (57.13 ± 3.29 kgs initial bodyweight) revealed that the control diet (0%CPCM) had the greatest digestibility percentages in all categories including dry matter, crude protein, crude fibre, gross energy, and total phosphorus (p < 0.05). Among CPCM replacement diets, the 15%CPCM generally verified a greater digestibility. The results of the feeding trial showed that there was no significant difference (p > 0.05) in feed intake, weight gain, feed conversion ratio, and haematological parameters among the four treatment diets. The haematological results showed that all parameters fall under the normal ranges of haematological pigs’ references. In conclusion, the results confirmed that CPCM can be used in the replacement of up to 15% in maize-soybean pig diets without any harmful effects.

The purpose of this study was to evaluate the changes in a non-conventional protein feedstuff with exogenous protease supplement using an in-vitro digestive trial contrasted to an in-vivo broiler trial.
Soybean meal (SBM), sunflower meal (SFM) and canola meal (CM) were used as the protein feed source, with or without the same activity of bromelain (750 units / solids) or microbial protease (45 units / solids) administered in 9 treatments for a 3 × 3 factorial experiment. The results showed that protein and amino acid digestibility and the percentage of water-soluble protein of SFM after in vitro digestion was significantly higher than the other trial diets. There was a significant affect on amino acid digestibility form the exogenous proteases supplement. The water soluble protein distribution showed that the percentage of molecular weight greater than 150 kDa in the SBM was higher than the other trial proteins. The molecular weight less than 1 kDa in SFM was significantly lower than the other. The SDS - PAGE polypeptide distribution showed the same soluble protein trend.
Ninety, fourteen day old and 45, thirty-five day old Arber Acer broilers used for the in vivo availability trial were randomly divided into 9 groups for a 3 × 3 factorial experiment. The experimental diet was formulated into an isonitrogenic semipurified diet with the same protein and exogenous proteases supplement used in the in—vitro trial. The result showed that the SFM protein and amino acid availability was higher than SBM and CM in the growth and finishing periods. The plasma total free amino acid concentration taken in the first hour after a meal had same trend as the availability data (P < 0.05). Compared with the control, the addition of microbial protease had a significant effect on improving protein and amino acid availability and total free amino acids in the plasma. The bromelain supplement showed no improvement on protein and amino acid availability.
Seven hundred and four Arber Acer chicks used for the growth trial were randomly divided into 32 pens for a 4 × 2 factorial experiment. The treatment involved four levels of SFM protein substitute of SBM protein (0, 5, 10 and 20 %) in isoenergenic and isonitrogenic diets, with or without microbial protease supplement. Results showed that there were no significant differences in feed intake, efficiency and weight gain during the growing period between all treatments. During the finishing period and for the entire trial period, feed intake and weight gain increased with increasing levels of SFM in the diet. Addition of microbial protease to the diet had a significant effect on improving growth performance.
In-vitro digestive trial and in-vivo availability trial showed SFM protein is hydrolysed by digestive enzymes more easily than the other protein source. We must think upon all effect to realize the applicability of SFM. So, besides the amount of crude protein and amino acid is not enough to broilers. High dirtary fiber content in SFM may affect broilers’ performance. There was no significant effect on feed efficiency when a SFM protein substitute of 20 % SBM protein was used in the growth trial.

Feed and nutrition play a crucial role in the quality and quantity of livestock production, both ruminants and non-ruminants. As a result, the supply of feedstuff resources has not met the needs of animal populations, which might lead to decreased performance, poorer health, increased erosion, and overgrazing, which would increase the number of livestock animals. To meet animal protein requirements, feed availability with a low price containing high quality is a big challenge for nutritionists in the future quality. Conventional methods were used to increase livestock improvements, including livestock diseases, management, nutrition, genetics and breeding that resulted in enhancing livestock production. Currently, these methods are no longer sustainable; modern techniques, especially biotechnology, are required for optimum productivity. Utilizing natural and organic resources, for controlling food-borne diseases, modern biotechnology techniques are needed to implement the bitterness of the livestock population, increasing food safety and reducing poverty for livestock farmers. Due to advances in livestock nutrition, there has been a focus on enhancing livestock requirements, to understand the demand and availability of the ingredients, and composition and formulating cost-effective diets with optimum nutrient availability.

Soybean meal and yellow corn are conventional feedstuffs used as the main ingredients in poultry feeds due to their high nutrients availability. On the other hand, these two feedstuffs are high in demand by other animals (soybean meal) and humans (yellow corn). By the year 2050, the world’s population is expected to increase up to 9.1 billion. Global consumption of poultry products, such as meat or eggs is increasing predominantly in developing countries. Consequently, the global demand for poultry feedstuffs would increase. The availability of feedstuffs for poultry nutrition nowadays is becoming more competitive. Thus, food security, especially in the developing countries, would be threatened. Currently, efforts are being made to use alternative feedstuffs to substitute portion of soybean meal and yellow corn in poultry diets. This chapter discusses the alternative feedstuffs that can be incorporated in poultry feeds. In addition, the nutritive content and availability are examined as well as how to improve the nutritive quality of such nontraditional feedstuffs.

The evolution of poultry nutrition has been driven by a quest for efficient production that aligns with environmental sustainability. Poultry, encompassing a range of domestic avian species, plays a pivotal role in meeting global demands for meat and eggs. The foundation of poultry nutrition rests on fundamental nutrients—water, energy, protein, minerals, and vitamins—each orchestrating essential physiological functions. Advancements in poultry nutrition have burgeoned to address the challenges of intensifying production. Non-conventional feedstuffs, such as alternative energy and protein sources, have emerged as viable alternatives to traditional grains. The integration of phytobiotics, enzymes, probiotics, and prebiotics into diets showcases innovative strategies aimed at enhancing digestion, immunity, and overall performance. However, the strides in poultry production must be weighed against their environmental impact. Intensification has led to waste materials like poultry litter and manure, causing pollution, greenhouse gas emissions, and the development of antimicrobial-resistant pathogens. The push for sustainability requires a delicate balance between productive growth and ecological preservation. In conclusion, poultry nutrition stands at the crossroads of progress and responsibility. The journey towards efficiency and quality intertwines with the imperative of sustainable practices. This abstract encapsulates the intricate pathways of poultry nutrition, culminating in a call for harmony between production and the well-being of our environment.
