Intact male lambs of the Berganês (BG), Berganês x Santa Inês (BSI), and Berganês x Dorper (BD) genotypes and the control group Dorper x Santa Inês (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&lt0.05). On the other hand, BSI, BD, and DSI showed higher cold carcass yield than BG (P&lt0.05). Lower cooling losses (CL) and more excellent conformation were observed in DSI (P&lt0.05). BD showed a higher carcass compactness index (CCI), and DSI showed a higher leg compactness index (LCI) (P&lt0.05). PCA produced seven components explaining 83.59% of total data variability. Based on the discriminant analysis, LCI, CL, CCI, and conformation showed greater power to distinguish the genotypes, with a high index of the lambs? classifcation to their respective genotypes. The crossbreeding improved carcass yield and reduced cooling weight loss. The Berganês ecotype and its crossbreeds have performance and carcass traits compatible with the DSI genotype. According to the DA, heterogeneity was found between the Berganês ecotype and its crossbreeds, with CL, LCI CCI, and conformation showing greater discrimination power.  aCarcass yield  aDiscriminant analysis  aOvino  aTerminação  aAnálise de componentes principais  aOvelhas Berganês  aOvinos mestiços  aRendimento de carcaça1 aMOURA NETO, J.
