Popis: This study aimed to evaluate the performance and carcass of lambs of different genotypes through univariate and multivariate analysis. Intact male lambs of the Berganes (BG), Berganes x Santa Ines (BSI), and Berganes x Dorper (BD) genotypes and the control group Dorper x Santa Ines (DSI) were used. Eight lambs of each genotype were used, aged between 4 and 5 months, with an average initial weight of 27.52 ± 3.79 kg, distributed in a completely randomized design. Data were tested by analyzing variance, followed by Tukey’s test and principal component analysis (PCA) and discriminant analysis (DA). Slaughter body and average daily gain were higher for BD and BG than BSI (P
