The objective of this trial was to evaluate the effect of weaning age on growth and carcass characteristics of calves from primiparous Bos indicus x Bos taurus crossbred cows. Heifers were divided in two groups according to the order of access to pasture and rotationally grazed pastures of ryegrass (Lolium multiflorum Lam) and arrowleaf clover (Trifolium vesiculosum cv. Yuchi) from weaning until their first mating season (two winter/spring seasons); animals were then transferred to native pasture in the following summer-autumn […]

Live weight at the beginning of the finishing period (IFW), average daily gain (ADG), slaughter weight (SW), cold carcass weight (CCW), carcass dressing percentage (DP), subcutaneous fat thickness (SFT) and slaughter age in days (SA) of 32 castrated males Braford, previously weaned at 100 (EW) or 180 days (CW) and slaughtered at 13-14 months old, were evaluated. From CW (03/06/01) until the beginning of finishing period (08/09/01), when passed to an improved pasture of ryegrass (Lolium multiflorum L.), the calves […]
