This study compared different management systems applied early in life on body development, endocrine parameters and age at puberty in beef heifers grazing Campos grassland, from 75 to 539±1.5 days of age. Calves were allocated to three treatments: 1) Early weaning (EW, n=15) at 75±1.5 days of age; 2) Traditional weaning (TW, n=14) at 158±1.5 days of age; 3) Traditional weaning plus creep feeding (TW+CF, n=17). Early weaned and TW+CF calves received a supplement that supplied 26±1.1% of crude protein and 11.7±0.04 MJ ME/kg DM from 75 to 158±1.5 days. Traditional weaned calves had a greater average daily weight gain (0.86±0.03 kg/day; ADWG) than EW calves (0.75±0.03 kg/day) from 75 to 158±1.5 days, associated with greater IGF-I concentrations at the time of TW (112.9±10.7 and 63.4±10.3 ng/mL respectively; P<0.05) that had no impact on age at puberty. Traditional weaning plus CF calves had a superior ADWG from 75 to 158±1.5 days (1.25±0.03 kg/day; P<0.05), greater concentrations of IGF-I at weaning (185.3±9.6 ng/mL), were heavier and taller (P<0.02) from weaning to 539±1.5 days, and puberty occurred earlier (472±8.0 days of age) than EW (526±7.2 days of age; P<0.05) and tended to occur earlier than TW calves (484±3.4 days of age; P=0.06). We conclude that age at weaning had a short-term impact on body growth and IGF-I concentrations, that had no effects on the age at puberty. However, CF induced a faster body development, which was related to an earlier attainment of puberty. |
