Abstract
   The influence of breed and body weight on the technical indicators of slaughter in cattle was studied. In this sense, 30 males from "Bălţată cu Negru Românească" and "Brună" breeds were slaughtered, respectively, falling into three weight groups (300-350 kg, 350-400 kg; 400-450 kg), establishing the slaughter yield. and the weight of the main anatomical portions in the carcass. From the obtained data it resulted that, in the Bălţată cu Negru Românească breed, the carcass weight was higher by 2.75-5.11%, hence a higher slaughter yield by 1.90-3.57% than in the breed Brown. Also in the Bălţată cu Negru Românească breed, there were higher weights for the anatomical parts included in specialties (by 0.26-0.46%), in those of superior quality (by 0.11-0.83%) and, respectively, in those of quality I (0.24-0.47%). Of the two breeds of cattle studied, the best slaughter indicators were made by Bălţata cu Negru Românească, especially by the specimens from the weight group 400-450 kg.
