Abstract:

As the rearing environment changed and the level of production rose, the importance of iron nutrition became more important. The regulation of iron metabolism has been one of concerns in recent years. In this paper, the nutritional status of iron in animal production, the regulation mechanism of 5-aminolevulinic acid on iron metabolism and its application in animal feed were reviewed. The bioproduction of 5-aminolevulinic acid is the rate-limiting reaction of heme biosynthesis process. The heme synthesis and utilization efficiency of iron was promoted by the dietary supplementation of 5-aminolevulinic acid. It provides a new approach for the regulation of animal iron metabolism.
