Thirty-two crossbred Santa Inês hair sheep lambs (16 males and 16 females) bred with their female progenitors on pasture of Brachiaria humidicola grass, supplemented in creep-feeding during the night, were allotted to a completely randomized design, in a factorial arrangement 4 x 2, four weaning ages (56, 70, 84 and 98 days) and sex to determine the best weaning age. At weaning, the lambs were confined in individual pens until 126 days old, when were daily fed Tifton 85 hay, water and mineral salt ad libitum and concentrate diet in the proportion of 2% body weight. There was a significant effect of weaning age vs sex interaction on DWC and DWG, where the males weaned at 84 days old were heavier than the females. No significant interaction of weaning age vs sex on DWBW and CFC was detected. Quadratic effects of weaning age on DWBW, DWG and CFC were noticed. No significant effect of sex on any of the studied parameters was detected. Seventy-six days weaned lambs maximized DWBW and DWG, while the most effective CFC was observed in seventy-two days weaned animals.
