A total of 96 pigs (PIC TR4 × 1050; initially 77.4 lb) were used in 2 14-d studies to determine the effect of standardized ileal digestible (SID) tryptophan to large neutral amino acids (LNAA) ratio on growth performance of finishing pigs. Results suggest that the high level of LNAA relative to tryptophan in diets containing 30% DDGS or greater may not be responsible for the apparentincrease in the tryptophan requirement of finishing pigs seen in previous studies.
