The amino acids level in the feeding diets was made based on the Standardized Ileal Digestability (SID) (NRC [26]).
CD (control diet), a basal diet; ED (experiment diet), a basal diet + 4% lysine, isoleucine, methionine, threonine, valine and tryptophan during growing phase, and a basal diet supplemented with 0.1% chromium picolinate during finishing phase.
