后备奶牛磷减排的营养措施
Research Advances in Phosphorus Emission Reduction in Holstein Heifers
摘要
Abstract
As the lack of research in phosphorus requirement of heifer nowadays,the content of phosphorus in heifer diet used in production is often higher than required,which results in serious environmental pollution by the excretion of excessive phosphorus. This paper reviewed the key roles of phosphorus in dairy cows’produc-tion,the recommendations of phosphorus content in heifer diet in different feeding standards,current situation of phosphorus excretion and related problems in scaled dairy farms,and discussed some effective nutritional ways to reduce phosphorus emission of heifers.关键词
