Zusammenfassung:The aim of this study was to analyze the effects of genetic group and sex on residual feed intake, performance, testicular size, carcass and morphometric traits in Santa Ines purebred and Dorper " Santa Ines crossbred lambs. A total of 32 lambs, with initial body weight of 18 +/- 3.7 kg were used. Analysis of variance, considering the interaction between sex and genetic group of all the traits were performed. Crossbred females (-0.018 +/- 0.06) and purebred males (-0.018 +/- 0.05) were more efficient (p
