Research Progress on Application of Organic Trace Elements in Swine Production
Trace mineral elements(referred to as"trace elements")are essential nutrients for animals to main-tain body health,and play a vital role in growth development and metabolism.In recent years,organic trace el-ements have attracted much attention because of their characteristics of high absorption and utilization,high bi-ological potency,low toxicity and environmental protection,and are used as feed additives.In this paper,the definition,classification,absorption mechanism,research and application of organic trace elements in pig pro-duction were introduced,in order to provide reference for organic trace elements to effectively replace inorgan-ic trace elements in pig breeding and further study.[Chinese Journal of Animal Nutrition,2024,36(11):6817-6825]
