Research progress on impact of trace elements on production performance of laying ducks
Trace elements are essential nutrients for the growth and development of poultry and livestock,serving as components or catalysts for various enzymes in the body.They regulate life activities by controlling the synthesis and secretion of enzymes and have a significant impact on the production performance and product quality of animals.Zinc and manganese play crucial roles in the formation of eggshell,affecting its ultra-microstructure and thereby influencing eggshell quality.Selenium has the function of regulating the antioxidant capacity and stress resistance.Currently,the trace elements supplemented in production are mostly inorganic forms,which have low absorption and utilization rates,and excessive addition can lead to residue and environmental pollution.Organic trace elements have the advantages of high absorption rate and strong stability,and using organic forms of trace elements in feed instead of inorganic forms has become a trend.The article reviews the impact of trace elements on the production performance of laying ducks,aiming to provide a reference for the rational application of trace elements in the production of laying ducks.
