Resumo: 	The ideal protein concept for pigs has allowed reducing levels of crude protein in the diet, since synthetic amino acids are included because the branched chain amino acids may be limiting. In order to determine the digestible isoleucine requirement for gilts from 15 to 30 kg, a performance assay was accomplished, using 40 crossbreed gilts of high genetic potential, averaging 15.00 ± 0.52 kg of body weight, alloted in a randomized blocks design, consisting of five treatments (0.45, 0.52, 0.59, 0.66, 0.73% of digestible isoleucine), four replicates and two animals per experimental unit. Performance traits were determined and at the end of the experiment one animal per experimental unit was slaughtered to determine carcass composition and organs weight. Levels from 0.45 to 0.73% of digestible isoleucine did not affect the carcass traits and organs weight of gilts from 15 to 30 kg. A quadratic effect (P&lt;0.05) of digestible isoleucine levels on isoleucine efficiency for weight gain was observed, that increased up to 0.506% digestible isoleucine, which ratio of digestible isoleucine: lysine was 0.51.
