ABSTRACT
The aim of this study was to evaluate the effects of using crambe cake in diets for sheep on intake and digestibility. The experimental design was a 4x4 Latin square with four animals, four periods and four treatments. The treatments were diets with 30% sorghum silage and 70% crambe cake (30:70) and a diet with 70% sorghum silage and 30% crambe cake (70:30) in lambs under the voluntary and controlled intake. The animals who fed a diet with a 30:70 ratio consumed more dry matter (DM), crude protein (CP), ether extract (EE) per kg/day, %BW/day and g/kgPV0,75. The ration provided higher digestibility of DM and NDF. The animals in the voluntary regime presented higher consumption of DM, CP, EE per kg/day, %BW/day and g/kgPV0,75. The cake crambe presented digestibility coefficient higher than sorghum silage, regardless of the regime intake. The 30:70 ration presented a difference in N intake and N absorbed. The cake crambe has high nutrient digestibility and acceptance by animals when associated with sorghum silage.
