SOYBEAN HULLS AS A REPLACEMENT FOR GROUND CORN IN RATIONS FOR LACTATING CROSSBREED COWS

Animal nutritionAbstract
Twelve lactating dairy cows were randomly assigned in four 3x3 Latin squares to evaluate milk production and composition when ground corn was replaced by soybean hulls in the diet. Soybean hull was added to the diet to progressively decrease ground corn (24%, 15% and 5.8% on the dry matter basis) while soybean hull was simultaneously increased to 21%, 30.1% and 39.3% (dry matter basis). Both milk production and 3.5% fat corrected milk production, milk protein (3.26 g/100 g) and milk lactose (4.67 g/100 g) were not affected by treatments (P>0.05). However, milk fat, milk solids and milk urea nitrogen increased linearly with the increasing levels of soybean hulls (P<0.01). It was concluded that the replacement of corn grain by soybean hulls did not affect milk production, but there was increase in milk solids, specifically milk fat.KEY WORDS: Byproduct feeds, milk yield and composition, milk urea nitrogen.
