摘　　要：钙磷作为重要的矿物质元素,在猪的生长发育、新陈代谢、神经活动、免疫功能等生理过程中发挥着关键作用。钙磷摄入不足、积蓄过多、比例失调等,均可引起严重的营养代谢疾病。随着畜牧业的迅速发展,钙磷大量添加导致的资源浪费、饲料成本增加以及环境污染等问题日益严重,实现畜禽饲粮钙磷的精准供给意义重大。因此,本文综述了钙磷在体内的分布、吸收、转运、代谢及其互作机理,并总结了仔猪的钙磷需求和不同来源钙磷的吸收效率,以期为饲料钙磷精准供给提供参考。As important mineral elements,calcium and phosphorus play key roles in the physiological processes of growth and development,metabolism,nerve activity and immune function in pigs.Insufficient intake and excessive accumulation or imbalance of calcium and phosphorus can cause serious nutritional and metabolic diseases.With the rapid development of animal husbandry,the massive addition of calcium and phosphorus caused the waste of resources,the increase of feed cost and environmental pollution.It is of great significance to realize the accurate supply of calcium and phosphorus in diet of livestock and poultry.Therefore,this paper summarized the distribution,absorption,transport,metabolism and interaction mechanism of calcium and phosphorus,and summarized the requirement of calcium and phosphorus in piglets and the efficiency of different sources of feed-stuffs,in order to provide a theoretical basis for the accurate supply of calcium and phosphorus in feed.
