Buffalo (Bubalus bubalis) is one of the most important livestock species populated largely in tropical and sub-tropical countries. Balanced and economical feeding of Buffalo is extremely important for optimum productivity. Lower production is mainly due to the scarcity of feeds and unbalanced feeding practices. Proper nutritional management is the key to a successful Buffalo reproduction and health program. Increasing milk production of cattle through increasing dietary energy level is recognized in enhancing lactation potential. Buffaloes are mainly fed on crop residues and local grasses and need to be supplemented with deficient minerals for proper production performance. However, various problems must be discussed, including determining nutritional needs for buffalo growth, nutritional maintenance of metabolic and reproductive abnormalities, and recognition and utilization of the buffalo gut environment. Improved dairy buffalo nutrition in developing countries would involve extensive organized research and extension measures.
Substitution of corn with wheat associated with its variable energy content and detrimental effect on broiler performance. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients like wheat, barley or sorghum. The predominant Non Starch Polysaccharides (NSP) in wheat are the pentosans (arabinixylans). Nonstarch polysaccharides create a viscous environment in the gastrointestinal tract of broiler chickens thereby interfering with the digestion and absorption of nutrients. Broilers lack endogenous enzymes to degrade arbino-xylans of wheat. Supplementation of exogenous feed grade enzymes to the cereal based diets improve the performance of broilers. Enzyme supplementation of chicken cereals based diets has resulted in improved starch and nitrogen digestibility as well as improved absorption of starch, amino acids and lipids. Supplemental enzymes such as β-glucanase, xylanase, protease and amylase break the polymeric chains of NSP into smaller pieces, thereby improving their nutritional value. The study concluded that the supplementation of NSP-degrading enzymes in wheat-based diet improve growth performance, ileal viscosity and gastric passage rate in broiler chickens.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
