Impact Of Dietary Changes On Hepatic Homocysteine Metabolism In Young Broilers, Fauna M. Ganson, Padmakumar Pillai, Jason L. Emmert

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Information regarding the impact of sulfur amino acids (SAA) on hepatic homocysteine (Hcy) flux through the various metabolic pathways competing for Hcy in young broilers is lacking. An experiment was conducted to evaluate the impact of varying levels of dietary methionine (Met), choline, and betaine on hepatic Hcy flux in young broiler chickens. A standard starter basal diet was fed to chicks until 8 d of age; 12 experimental diets were given from 8-22 d. The experimental basal diet contained deficient levels of Met and cysteine (Cys); supplemental Met (0, 0.08, 0.16, and 0.24%) was added to the basal diet …
