Resumen

Eighteen Holstein x Zebu crossbred bulls of 296, 301 and 307 kg average liveweight per treatment were selected to study the productive performance of animals fed sugarcane forage and concentrate, with variation of the raw material used. They were located according to random block design with three treatments and six repetitions each. The treatments consisted of sugarcane forage + 50 g urea + concentrate 1 (A), sugarcane forage + 50 g urea + concentrate 2 (B), sugarcane forage + 50 g urea + concentrate 3 (C). An analysis of variance was conducted according to random block design. Duncan?s test (P < 0.05) was applied when necessary. The daily weight gain of treatment A was higher (P < 0.05) than that of treatment B. The feed conversion of treatment A was higher (P < 0.001) than the rest. There were no differences in the intake of total and sugarcane DM in the treatments used, with values of 7.74, 8.0, 8.05 and 5.08, 5.25 and 5.33 kg for each treatment, respectively. It is concluded that the use of soybean and maize meal increased the productive performance in respect to the use of wheat bran and dry distillery grains with solubles (DDGS) in diets with sugarcane as voluminous feeds.
Key words: fattening, distillery grains, soybean and maize meal, wheat bran.
