Resumo

The feedlot performance of 30 post-weaning 3/4 Canchim 1/4 Nellore calves, with seven months of age and 208,8 kg of liveweight, was evaluated. Three different protein sources in isocaloric and isonitrogenous diets with 60:40 forage: concentrate ratio were used. The diets, fed ad libitum, constituted of corn silage, corn grain, mineral mix and a different protein source for each treatment: cottonseed meal, soybean meal and whole soybean. The weight gain, feed: gain ratio, dry matter and crude protein intake were evaluated for the growing (84 days) and fattening phases (84 days) and for the overall period. An economic study of young bulls production model was realized at the end of experimental period. Soybean meal based diet presented the best animal performance and provided R$ 51.30/head of net profit - the best economic result.
