A total of four studies were conducted in an effort to determine the impact of Trp and the BCAA in swine diets containing DDGS or HPDDG on the growth performance and carcass characteristics of the growing and finishing pig. The first study utilized 1,170 pigs (PIC 800 x PIC, initial BW 38.6 kg) in a 98-d grow-finish study to determine the performance response of pigs fed increasing levels of SID Trp:Lys in swine diets containing 40% DDGS. Treatments consisted of diets containing 40% DDGS with a SID Trp:Lys ratios of 15, 18, 21, or 24% or a corn-SBM diet for …
