Regression-Derived Ileal Endogenous Amino Acid Losses In Broiler Chickens And Cannulated Pigs Fed Corn Fiber, Wheat Bran, And Pectin, Sunday A. Adedokun, Olayiwola Adeola

Animal and Food Sciences Faculty Publications

The objective of these studies was to determine the effect corn fiber (CF), wheat bran (WB) and pectin (PEC) on basal ileal endogenous amino acid (EAA) losses in broiler chickens (Exp. 1) and cannulated pigs (Exp. 2) using the regression method. Semi-purified diets containing 100 g/kg of CF, WB, or PEC (broiler chickens) and CF or PEC (pigs) were fed to replicate cages consisting of eight birds per cage of 21-d-old broiler chickens and six replicates of pigs consisting of one pig per pen. Ileal endogenous His, Glu, and Pro losses were higher (p < 0.05) for CF and WB compared with birds fed diets containing PEC. Contrasts between CF and WB showed higher (p < 0.05) ileal endogenous nitrogen, total amino acid, His, Ile, Met, Glu, Pro, and Tyr losses in birds fed the CF diets (Exp. 1). Contrasts of EAA losses between birds fed the WB and PEC diets showed higher (p < 0.05) losses for His, Glu, and Pro. In the cannulated pigs, CF resulted in higher (p < 0.05) ileal endogenous His, Leu, and Tyr losses. In summary, CF induced higher ileal EAA losses in broiler chickens and cannulated pigs.

Investigating The Potential Of Sodium Butyrate To Control Salmonella Enteritidis In Poultry, Anamika Gupta

Graduate Theses and Dissertations

Salmonella Enteritidis (SE) is a major poultry associated food borne pathogen that causes enteric illnesses in humans. Despite using various pre-harvest and post-harvest intervention strategies to reduce Salmonellosis, SE infection is still an extensive problem in the poultry industry with increased incidences since SE has developed multiple strategies to adapt in the chicken intestinal tract particularly in the ceca. Therefore, reducing SE in the intestine of chickens would reduce contamination of poultry derived foods and minimize the risk of human infection. Short chain fatty acids such as butyrate are microbial metabolites known to modulate inflammatory response. In this dissertation, the …
