摘要

[Objective]The paper was to study the effects of extruded cottonseed meal on the nutrition of dairy cows.[Method]Holstein cows were selected for feeding and milk production test.[Result]Extruded cottonseed meal could substitute soybean meal,and there was no significant difference in milk yield and butter-fat percentage.Extruded cottonseed meal could increase milk yield when substituting corn germ meal.In addition,the health of diary cow had not been affected.[Conclusion]Extruded cottonseed meal could guarantee protein nutrition,increase milk yield,reduce feed cost and improve economic benefit of dairy cows when substituting soybean meal and corn germ meal.
