摘　　要：为了调查我国不同地区饲料原料中磷含量的分布状况,合理利用饲料资源,本研究共采集全国31个省(市、自治区)的4 054份饲料原料,测定其总磷含量。结果表明:1)不同种类饲料原料中平均磷含量变化范围在0.35%~7.77%,磷含量分布规律为:矿物质饲料>动物性蛋白饲料>植物性蛋白饲料>谷类籽实加工副产品>牧草类饲料>秸秆类饲料>谷类籽实,同一种类不同饲料原料的磷含量也存在显著差异(P<0.05)。2)以省为单位,对玉米、小麦和豆粕的磷含量进行地区间比较,结果表明,饲料原料中磷含量受地域因素的影响较大(P<0.05)。不同种类和不同地区饲料原料中磷含量差异较大,使用饲料原料的磷含量平均值配制饲粮会影响其准确性。本研究结果有助于饲料生产者根据饲料原料中实际磷含量精准配制饲粮,在确保动物健康及高效生产的同时,降低饲料成本、减少磷元素排放对环境的污染。In order to investigate the distribution of phosphorus(P) contents in feedstuffs from different regions of China and make a rational use of feed resources, we analyzed P contents in 4 054 feed samples collected from 31 provinces(cities, municipalities) in China. The results showed that: 1) The average P contents in different kinds of feedstuffs ranged from 0.35% to 7.77%. The distribution regularities of P contents were as follows: mineral feeds > animal protein feeds > plant protein feeds > cereal by-products > forage grass feeds > straw feeds > cereals. A significant difference was also observed in P contents among different feeds in the same category(P<0.05). 2) Regional comparisons among different provinces were made in P contents of corn, wheat and soybean meal, and the results showed that the P contents in feedstuffs were greatly affected by environmental changes in different regions(P<0.05). P contents in feedstuffs varied with the types of feedstuffs and different regions. The formulation of diets by using the average P contents in feedstuffs could influence its accuracy. The results from the current study would be of great significance toward having a knowledge of actual P contents in the feedstuffs to precisely formulate diets in order to ensure animal health and efficient production, and reduce feed cost and the environmental pollution of P excretion.
