As we know, China is the second largest producer and consumer of broilers in the world. Chicken, which contains high protein content, low fat level and easily absorbed features, is the second largest meat source following porkin the Chinese diet. Iron is an essential trace elementin broilers’ growing process, especially the iron requirements of fast-growing broilers are high.However, there are many factors that limit dietary iron absorption and utilization, so the iron that broilers obtained from diets can’t meet the needs of optimum growth. In order to ensure better performance of broiler, usually we add exogenous iron in broiler diet.The frequently used form in broilers’ diet is inorganic iron. Currently, we have recognized the disadvantages of inorganic iron, such as hygroscopic, oxidative damage to vitamins and other feed components, low absorptive efficiency. Thus various kinds of organic iron have been developed and used in the feed industry, and some of them are more stable and similar with the forms in vivo.
