Replacement of corn silage by orange peel silage in the feeding of dairy cows: Intake, milk production and composition

[摘要] - The effects of the replacement of corn silage by orange peel silage were studied on the intake of nutrients, production and quality of the milk of Holstein dairy cows. A 4 x 4 Latin square design with four replacement levels (0, 25, 50 or 75% DM) of corn silage by orange peel with forage to concentrate ratio of 50:50 were used. The replacement levels did not affect the percentage of milk fat and milk protein, however the nutrient intake and milk production showed a quadratic behavior in function of the replacement level of corn silage by orange peel silage. The results suggest that the silage of orange peel can substitute the corn silage for lactating dairy cows.
