| Popis: | This study evaluated the effects of standardized ileal digestible (SID) tryptophan and B6 on blood parameters, organ weights, carcass traits, and longissimus lumborum quality of barrows (70-100kg). Sixty-four crossbred barrows averaging 70.77±2.07kg were distributed in a 4×2 factorial with four SID tryptophan levels (0.130, 0.155, 0.180, and 0.205%) and two B6 levels (1 and 5mg/kg) in eight replicates of one animal each. The meat lightness degree answered linearly (P=0.015) to SID tryptophan levels and the shear force answered quadratically (P=0.050), with estimates of a higher value (31.67N) at 0.163% SID tryptophan. Although B6 showed positive effects (P |
