Estimation of the optimal ratio of standardized ileal digestible tryptophan to lysine for finishing barrows fed low protein diets supplemented with crystalline amino acids
tryptophan requirement pig performance
2015/7/3
Optimum standardized ileal digestible (SID) tryptophan (Trp) to lysine (Lys) ratio was estimated for 67–96 kg barrows fed low protein diets supplemented with crystalline amino acids (AA). One hundred ...
