| Abstract | The objective was to study the effects of partial replacing of corn silage by corn gluten feed (CGF-21) dehydrated on milk production and composition of milk and in the blood parameters of dairy cows, beyond the economic evaluation. Inclusion levels of 0, 8 and 16% of CGF-21 (% DM) to the diets were evaluated. Thirty cows were used for study of milk production and composition and fifteen cows for blood parameters study. A 3 x 3 Latin Square experimental design with ten replications was used. There was difference among diets for milk yield and for 3.5% fat correct milk. No difference among diets was observed for the other studied characteristics. The results obtained for milk yield were: 22.44, 23.69 and 23.88 kg/anim.d and for 3.5% fat correct milk were: 23.25, 24.71 and 24.44 kg/anim.d, respectively, for the inclusionj levels of CGF-21 for the inclusion levels of 0, 8 and 16% of CGF-21 in the diet. The results obtained for the composition of milk were: percentage of fat, 3.69, 3.76 and 3.65%; milk protein, 3.22; 3.20 and 3.25%; lactose, 4.29, 4.32 and 4.31%; total solids, 12.12, 12.23 and 12.14%; N-ureic milk, 16.57, 16.50 and 14.96mg/dL, and for blood parameters were: plasma N ureic, 109.92, 21.17 and 20.21 mg/dL, seric glucose, 55.69, 56.50 and 54.78 mg/dL, respectively, for the inclusion levels of 0, 8 and 16% of CGF-21 in the diet. The diet with the inclusion of 16% of CGF-21 result on a greater profit. |
