摘要: The objective of this study was to evaluate the ryegrass pasture production, forage quality and animal productivity in three sheep production systems: lambs weaned at 40 days age finished (Lolium multiflorum Lam.) until slaughter; kept with their dams same treatment, but were supplemented 1% live weight concentrate creep feeding. grazing method continuous variable stocking, order maintain 1,000 kg leaf dry matter per hectare. mean 3,236.6 DM/ha, lamina 1,008.7 DM/ha daily growth rate 58.38 kg/ha. With lambs, height (20.95 cm) higher when compared others. inflorescence pastures for (61.7 kg/ha) other systems. Weaned presented stocking 929.7 BW/ha, considering only without supplementation (259.9 kgBW/ha) or feeding (254.3 kgBW/ha). not different between structure changed due selectivity pasture. weaning system reduced lower individual performance lambs; therefore, should be recommended breeders.
