Todos os textos, informa??es e resultados apresentados s?o de inteira responsabilidade dos autor.Objetivou-se avaliar o efeito de inclus?o crescente da prote?na bruta do farelo de crambe em substitui??o ? prote?na bruta do concentrado fornecido a cordeiros confinados em rela??o ao consumo de nutrientes. Foram utilizados vinte e quatro ovinos SRD machos, com idade inicial m?dia de quatro meses e peso vivo m?dio inicial de 17,50 ? 3,90 kg. As dietas foram constitu?das com n?veis crescentes de; 0%, 25%, 50%, 75% de substitui??o da PB do concentrado pela PB do farelo de crambe. Houve efeito linear decrescente da inclus?o do farelo de crambe nas dietas dos animais em rela??o ao consumo de mat?ria seca (CMS), consumo de mat?ria org?nica (CMO),consumo de prote?na bruta (CPB) e consumo de carboidratos n?o fibrosos corrigidos para cinzas e prote?nas (CCNFcp) em Kg.dia-1. Conclui-se que o farelo de crambe utilizado como alimento prot?ico substituindo at? 75% da prote?na bruta do concentrado diminui o consumo de PB e CNF em kg MS.dia-1 de cordeiros confinados, todavia n?o alterou o consumo dos nutrientes na unidade g. Kg-1 de PV.ABSTRACT The objective was to evaluate the effect of increasing inclusion of crude protein of crambe meal to replace the crude protein of the concentrate fed to feedlot lambs in relation to nutrient intake. Twenty-four sheep SRD rats were used, with initial mean age of four months and average weight of 17.50 ? 3.90 kg. The diets were made with increasing levels of; 0%, 25%, 50%, 75% replacement of PB PB concentrated by crambe bran. Decreased linearly the inclusion of crambe meal in animal diets in relation to dry matter intake (DMI), consumption of organic matter (CMO), crude protein intake (CPB) and consumer non-fibrous carbohydrates corrected for ash and protein (CCNFcp) in Kg.dia-1. Concluded that the crambe meal used as protein feed by replacing up to 75% of gross protein concentrate decreases the consumption of PB and CNF in MS.dia kg-1 of lambs, however not alter the intake of nutrients in g unit.
