Abstract: Manganese is one of the essential trace elements for livestock and poultry，and plays an important role in the breeding of livestock and poultry，especially in poultry. Manganese is an important component or activator in the biosynthesis of various enzymes，which is closely related to broilers’growth，bone development，reproduction，and immunity. Both the deficiency and excess of manganese will have a greater negative impact on broilers. Manganese is mainly added in the form of inorganic manganese（manganese sulfate，manganese oxide，manganese chloride and manganese carbonate，etc.）and organic manganese（protein manganese and amino acid manganese，etc.）. Studies have shown that organic manganese has a higher biological availability than inorganic manganese but is expensive. In broiler chicken production，how to efficiently select different forms of manganese according to the appropriate amount of manganese in broiler feed is particularly important，to improve the growth performance of broiler chickens. At the same time，reduce the adverse impact on the ecological environment caused by excessive manganese discharge. In the present article，the biological characteristics，added forms，added amounts，and application prospects of organic manganese were reviewed，to provide theoretical support for the efficient and reasonable application of manganese in broiler production.
