摘　　要：铁是动物体内所必需的微量元素之一。常规饲料中的含铁量能够满足动物机体的需求,但畜牧业生产中使用的饲粮主要为植物性原料,其中所含的铁主要是非血红素铁。动物机体对非血红素铁的吸收容易受到植酸、铜、锌、日粮纤维以及单宁等抗营养因子的影响,导致动物对铁的利用率降低。近年来,生物基因工程技术在育种上得以广泛应用,使得动物的生长性能、繁殖性能等指标得到极大的改善,动物对饲粮中添加剂的营养功能要求也更加全面。文章主要对微量元素铁的营养代谢功能以及在猪生产中的应用进行简单介绍。Iron is an essential trace element in animals. The normal diet iron content is able to meet nutritional needs of livestock. But it used in the diet in animal production is mainly plant feed, which contained mainly non-berne iron. The absorption of non-heme iron is susceptible to interference phytic acid, copper, zinc, dietary fiber and tannin and other anti- nutritional factors. It results in the decrease of animal utilization of iron. In recent years, the biological genetic engineering technology is widely used in breeding, it makes growth performance, reproductive performance of animals and other indicators have been greatly improved. Thus animal diet additive functional requirements needs more comprehensive. The article described iron nutrition function and application in pig production.
