The alm of this work was to establish the effects of ryegrass (Lolium multiflorum Lam.) pastures in two tillage systems on performance in the late rearing and weight at mating of hogget ewes Polwarth sheep. The hogget ewes were eight months old and had 29.873Kg liveweight, allocated in a completely randomized design with the treatments: ryegrass in conventional tillage (A/C) vs. ryegrass with minimum tillage- (A/S). The analysis of variance showed that A/C pasture were superior (P<0,05) for liveweight gain. Conclusions: 1) the ryegrass pasture in conventional tillage is superior in liveweight gain: 2) the ryegrass pastures in both tillage systems are superior to those performances of traditional breeding sheep conditions raised on native pastures, largely used in the Rio Grande do Sul state, Brazil.
