The objective of this study was to evaluate the growth of young heifers from different genetic groups in an intensive meat production system. One hundred and thirty two heifers from four different genetics groups were used: 18 – ¾ Canchim × ¼ Nellore (¾ CN), 18 – ½ Canchim × ½ Nellore (½ CN), 24 Simbrasil – ⅝ Simmental × ⅜ Nellore (SIMB) and 72 – Three way cross ¼ Simmental × ¼ Nellore × ½ Angus. The heifers were […]

With the aim to study carcass traits, nine Gyr, nine Guzera, nine Nellore and nine Mocho Tabapuã bulls, averaging, respectively, 357.6, 362.0, 368.6, and 376.4 kg of initial live weight and 24 months of age were used in this study. The animals from each breed were randomly assigned to individual pens and were full fed a diet containing 50% concentrate, dry matter basis, until the slaughter weights (405, 450 and 500 kg LW). At slaughter the empty body weight was […]
