  1. aAID Apparent ileal digestibility, SID Standardized ileal digestibility. AID values of crude protein and amino acids were calculated using the exogenous indicator method, and values for SID were calculated by correcting the AID values with the basal endogenous losses. In the current study, the averaged basal endogenous losses for crude protein, lysine, methionine, threonine, tryptophan, valine, lecuine, isoleucine, phenylalanine, histidine, arginine, tyrosine, serine, glutamic acid, proline, glycine, alanine, cycstine and aspartic acid measured through animal trials were 14.00, 0.50, 0.12, 0.81, 0.37, 0.60, 0.63, 0.36, 0.36, 0.26, 0.54, 0.16, 0.66, 0.90, 1.16, 1.50, 0.60, 0.31 and 0.90 g/kg dry matter intake, respectively, all within the reseanable ranges reported previsously [29]
