Abstract 

The experiment was performed to determine the effects of supplements on the performance of 40 crossbred Limousin-Nelore young bulls, aged 17 months old with an average liveweight of 367 kg, in Brachiaria decumbens postponed pasture during the dry season. The animals were distributed in five treatments: mineral complex only (control); 1.49% mineral complex+1.99% urea and cracked corn, soyabean meal and wheat bran in different percentages. The treatments had 24% crude protein in DM and different non-fibrous carbohydrates (NFC) and neutral detergent fibre (NDF) contents. The concentrates were offered in amount equivalent to 1% of animal liveweight on original matter basis. The experiment was analysed in completely randomized design, with five treatments and eight replications. The influence of pasture characteristics on the performance of supplemented animals was studied. The results showed that young bulls can be finished on tropical pastures during dry season using supplements. The animals with supplements exhibited similar average daily gains (ADG), but showed higher ADG than the control animals, respectively, 915 and 104 g/day. ADG was linearly and negatively correlated with availability of dead forage dry matter, and it was linearly and positively correlated with availability of green forage dry matter, and availability of green forage dry matter/dead forage dry matter ratio, green forage dry matter/total forage dry matter ratio, green leaf dry matter/dead forage dry matter plus green stem dry matter ratio, and green leaf dry matter/total forage dry matter ratio.
