It was evaluated the performance of female lambs on cultivated pastures of Italian ryegrass (Lolium multiflorum Lam.) and pearl millet (Pennisetum americanum (L.) Leeke) as exclusive food or as daily supplementation with commercial feed at the ratio of 0.5, 1.0 and 1.5% of the body weight. The used grazing method was continuous with variable stocking. Female lambs on Italian ryegrass pasture supplemented with 0.5 and 1.5% of body weight presented greater average daily gain. Regardless to the level, supplementation on Italian ryegrass pasture promoted the highest weight gain per area. In pearl millet pasture, the daily weight gain, the weight gain per area and body condition score were higher for the lambs under supplementation. The structure of Italian ryegrass and pearl millet pastures is not affected by the offer of supplement to the animals. The use of Italian ryegrass pasture during pre and post weaning periods associated to the supplementation at the levels of 0.5 and 1.5% of body weight on pearl millet pasture allows lambs to show weight and body condition score fitted for mating at nine months of age.
