The lots were not homogeneous for yield of commercial cuts and performance and morphometric traits evaluated in vivo. The groups were heterogeneous to 75% of the 13 carcass traits evaluated, among them, hot and cold carcass weights, hot and cold carcass yields, carcass grade finishing and biological yield. There was also no uniformity for the proportion of non-carcass components, morphometry of carcass, visual appraisals, and loin traits. On the other hand, homogeneity was achieved in physico-chemical and sensory traits, except for hardness and proportion of saturated, monounsaturated and polyunsaturated fatty acids. We conclude that the commercial finishing system with the use of undefined crossbred lambs does not produce carcass and cuts standardized to the market.  aBrazil  aLamb meat  aOvine carcasses  aSheep meat  aSlaughter weight  aYields  aÁcido Graxo  aCordeiro  aCorte  aEngorda  aOvino  aRendimento  aAcabamento  aBrasil  aCarcass morphology  aCarne ovina  aPeso da carcaça  aSensory analysis1 aCHAPARRO-PINZÓN, A.1 aMELO NETO, F.
