摘要
磷是参与动物机体多种生物学反应的必需元素之一,但畜禽养殖,尤其是反刍动物养殖过程中磷排泄带来的水体污染等环境问题已经成为业界关注的焦点,因此如何提高磷的利用率、减少磷排泄是行业亟待解决的问题。本文总结了反刍动物磷利用的相关研究进展,并结合其代谢特点归纳了提高磷利用率的措施,提出了下一步研究的方向。
Phosphorus( P) is one of the essential elements for animals,which participles in various biochemical processes in animals. Environmental concerns like water pollution by P from livestock farms,especially in ruminants,is a growing concern. It is a problem needed to be solved that maximize P efficiency and reduce P emission. This article summarized the studies relevant to P utilization in ruminants,and concluded measures to increase P utilization rate based on metabolism characteristics of ruminants,then put forward to the following research direction.
