摘　　要：磷是动物生长必需的矿物元素,植物原料中的磷70%~80%以植酸磷的形式存在,难以被家禽等单胃动物利用。近几年,随着蛋鸡育种发生变化及植酸酶技术的进步,蛋鸡对磷的需要量以及玉米-豆粕型饲粮中无机磷的添加量可能也发生了变化。本文综述了产蛋期蛋鸡磷需要量方面的研究进展,为磷在蛋鸡上的科学研究和精准应用提供理论参考。Phosphorus is a mineral that is essential to growth for animals.In plant-derived feed ingredients,approximately 70%to 80%of the phosphorus is stored in the form of phytate phosphorus.This phyate-bound phosphorus is poorly utilized by monogastric animals,such as poultry.In recent years,with the variety change of laying hens and the development of phytase technology,the phosphorus requirement of laying hens and the amount of inorganic phosphorus supplemental in cornsoybean meal diet may change.This article mainly reviewed the phosphorus requirement of laying hens,analyzed some flaws in the literatures,and gave some suggestions,aiming at providing theoretical references for the scientific research and precise application of phosphorus in laying hens.
