| Resumo: |
This study was performed to assess the animal performance of 97 bulls, ½ Purunã vs. ½ Canchim, that were slaughtered at 16 (16M) or 22 (22M) months with three concentrate levels (0.8, 1.2, and 1.6%) of body weight (BW). The initial body weight was lower for the 16M bulls. The final body weight and hot carcass weights were similar between the two slaughter ages. The hot carcass dressing was higher for 22M bulls. The average daily gain was higher for 16M bulls. The feed intake and dry matter feed conversion were similar between 16 and 22M bulls. The carcass length, marbling, and bone percentage were lower for 16M bulls. However, the Longissimus dorsi muscle area was higher for 16M bulls. The leg length, cushion thickness, fat thickness, conformation, colour, texture, muscle percent, and fat percent were similar between 16 and 22M bulls. The final and hot carcass weights were lower for bulls that were fed with 0.8% of BW. The carcass dressing was similar for the three concentrate levels. The average daily gain was higher for bulls that were fed with 1.6% of BW of concentrate and lower for those that were fed with 0.8%. The concentrate levels had no effect on carcass characteristics, feed intake, and dry matter conversion.
