Abstract

To evaluate the chemical composition and dry matter in vitro digestibility of concentrates with partial substitution of soybean meal with sunflower crushed, was used a randomized design with four treatments and four replications. The concentrates were composed of corn and soybean meal replaced by the sunflower crushes, in rates of 0, 20, 40 and 60%. The CP levels were not affected by the inclusion of sunflower crushed (P> 0.05), with mean of 28.1%, but the levels of EE, CF, NDF and ADF, where the replacement of 60% of soybean meal showed an average of 11.00, 14.78, 32.48 and 18.73% respectively. The increase in ADF, decreases total (TC) and non-structural (NEC) carbohydrates, DMIVD and TDN. The C00 had a higher IVDMD, 13.71% superiority of the C60, while C20 showed 8.96% of superiority. The TC and NEC reduced after 40% replacement, with an average of 57.62 and 26.15%. Concentrates with sunflower crushed presents average of NDT of 78.79%, reduction of 7.43% compared to the C00. Replacing up to 60% of soybean meal with sunflower crushed in concentrates; change the chemical composition and dry matter in vitro digestibility.
