摘要: Angus Plus cattle offer advantages for heat tolerance and forage utilization by introduction of Brangus Brahman to Angus. To evaluate its adaptability in Hawaii Islands, we reported the growth performances 213 F1 calve grazing on pasture. Least-square means pre-weaning ADG ranged from 1,087 1,167 g bull calves 1,030 1,048 heifer calves. The 205 d-adjusted weaning weight were 226 285 kg bulls 214 252 heifers. birth hip height at significantly correlated with weight, (P < 0.01). Sire group influenced through interaction sex calf. Bull sire high 1.0–3.8 heavier than other sires 0.001). x was significant 0.05) calf 205-d adjusted ADG. also played a role 0.05). Selections preferable improved performances.
