Reducing Dietary Crude Protein: Characterization Of Branched-Chain Amino Acid Antagonism In Modern Broiler Chickens, Craig William Maynard
Reducing Dietary Crude Protein: Characterization Of Branched-Chain Amino Acid Antagonism In Modern Broiler Chickens, Craig William Maynard
Graduate Theses and Dissertations
Reducing the crude protein content of broiler diets while maintaining performance has been a primary research area in nutrition. During the late 20th century, the bulk of this research has involved supplementing broiler diets with feed-grade amino acids and proving the economic benefits of their additions. To date, widespread adoption of feed-grade amino acids is limited to methionine, lysine, threonine, and to some extent valine. With valine and isoleucine gaining prevalence in commercial formulation, classic data on the antagonisms associated with the branched-chain amino acids has returned to the forefront of practical broiler nutrition research. Therefore, a series of 23 …
Evaluation Of Nutritional Factors That Influence The Efficacy Of Tributyrin As A Feed Additive For Broilers, Brooke Bodle
Evaluation Of Nutritional Factors That Influence The Efficacy Of Tributyrin As A Feed Additive For Broilers, Brooke Bodle
Graduate Theses and Dissertations
Tributyrin (TB) is a glyceride ester of butyrate that has the potential to improve broiler performance and intestinal development. Therefore, to fully evaluate this potential, three experiments were conducted to evaluate effect of tributyrin (TB) on broiler growth performance, nutrient digestibility, carcass characteristics, intestinal morphology, and gastrointestinal function in birds fed diets varying in composition reared in battery cages and floor pens. Experiment 1 explored the supplementation of graded doses of TB and its impact upon growth performance, nutrient digestibility, and carcass characteristics in a step-down program when added to a reduced energy and amino acid diet. A linear reduction …
