Resumo
Avaliaram-se os efeitos da suplementação concentrada de novilhos, durante o período das águas, sobre os conteúdos corporais de proteína e energia e as respectivas exigências líquidas para ganho de peso. Foram utilizados 49 novilhos mestiços, mantidos em pastagem de Brachiaria decumbens. O experimento foi conduzido em três períodos experimentais, segundo delineamento inteiramente casualizado. Foram fornecidos diariamente sal mineral (SAL), suplementos à base de milho e farelo de soja, com 20% PB, em nível de 1,0 e 2,0 kg/dia (MFS1 e MFS2), respectivamente, e suplementos à base de farelo de trigo e farelo de soja, com 20% PB, em nível de 1,0 e 2,0 kg/dia (FTFS1 e FTFS2), respectivamente. Não foram encontradas diferenças entre os tratamentos sobre os conteúdos corporais de proteína e energia para os tratamentos SAL, MFS1, MFS2, FTFS1 e FTFS2. Os animais submetidos aos diferentes tratamentos não exibiram diferenças na composição do ganho de peso para proteína, gordura e energia. As exigências líquidas de proteína e energia para um animal de 350 kg de peso vivo foram, respectivamente, de 220 g e 5,75 Mcal por kg ganho de peso vivo.
The effects of concentrate supplementation of stocked an during the rainny season on the body composition of energy and protein and net requirements of protein and energy for weight gain were evaluated. Forty-nine crossbred steers, were Brachiaria decumbens pastures, were used. The experiment was driven in three experimental periods, according to a completely randomized design. The following supplements were daily fed at 10 a.m.: mineral salt (SALT), supplements based on corn and soybean meal, with 20% CP, at the level of 1.0 and 2.0 kg (CSBM1 and CSBM2) and supplements based on wheat bran and soybean meal, with 20% CP, at the level of 1.0 and 2.0 kg (WMSBM1 and WMSBM2). The animals submitted to the different treatments showed no differences on composition of weight gain in the protein, fat and energy. The net requirements of protein and energy for an animal with 350 of body weight were, respectively, 220 g and 5.75 Mcal per kg of live weight gain.
