Three experiments were conducted to determine the Lys and TSAA requirement of 6- to 12-kg pigs. There were 5 replications of 5 or 6 pigs per pen (for Exp. 1, 2, and 3, n = 150, 150, and 168 with initial BW of 6.3, 6.7, and 6.4 kg and final BW of 10.8, 11.7, and 11.2 kg, respectively). In Exp. 1, pigs were fed in a 13-d growth assay and treatments were: positive control (PC, 40% corn, 38% soybean meal, 10% whey, 3% fish meal, 3% fat, and 1.45% true ileal digestible (TID) Lys), and TID Lys levels of 1.1, 1.2, 1.3, 1.4, and 1.5%. The addition of Lys increased G:F (linear, P |
