A total of 2,160 pigs were used in two groups with 27 pigs per pen and 10 replicates per treatment. Phase 1 was fed from day 0 to 28, phase 2 from day 28 to 56, phase 3 from day 56 to 84, and phase 4 from day 84 to 112.
DDGS included at 40% in phases 1 and 2, 30% in phase 3, and 15% in phase 4.
SID Thr:Lys was 61%, 6%2, 63%, and 65% in phases 1, 2, 3, and 4, respectively.
SID Thr:Lys was 67%, 68%, 69%, and 72% in phases 1, 2, 3, and 4, respectively.
