摘　　要：铅是一种常见的灰黑色重金属元素,在动物体内没有任何生理作用。动物体原本不应该含有铅,只是随着现代工业的发展,含铅产品的广泛使用,以及环境污染的日趋严重使饲料原料中含铅的机会越来越多。在畜禽生产中铅污染还未受到重视,然而研究显示较低剂量的铅就可能造成动物肠道损伤,降低畜禽的生产性能和肉蛋品质。本文从铅暴露对动物肠道吸收的影响的角度,分析铅暴露是如何降低动物生产性能,寄予能为动物养殖提供有利借鉴。Lead is a common black heavy metal elements, with no physiological function in animal body. The animal body originally should not contain lead, but with the development of modern in- dustrial products widely used in the lead, and lead to more serious environmental pollution in feed more and more opportunities. Lead pollution in livestock production has not received the at- tention, but research shows that low dose of lead may cause animal intestinal damage, reducing the quality of livestock and poultry production performance and meat and eggs. Analyzing lead ex- posure is how to reduce animal production performance, expected to provide a favorable reference for animal breeding, through the effects of lead exposure to the animal intestinal absorption
