Kansas Agricultural Experiment Station Research Reports

A total of 3 broiler diets were pelleted to determine the effects of diet formulation on pellet quality. Dietary treatments consisted of corn and soybean meal (SBM)-based control, the control with crystalline Val, and the control with crystalline Val and Ile. As crystalline amino acids (AA) increased in the diets, corn concentrations increased as SBM and choice white grease (CWG) were removed to balance for nitrogen-corrected metabolizable energy (MEn). Diets contained 54.2, 56.4, and 57.5% corn; 39.1, 37.1, and 36.2% SBM; and 2.5, 2.1, and 1.9% CWG in the control, Val, and Val + Ile diets, respectively. Corn was ground …
