Progress on the application of zinc cysteamine in animal production
[Objectives]The potential of applying zinc cysteine in animal nutrition and feed additives was studied to improve the production performance and the health of animals.[Methods]The progress on applying zinc cysteine in animal production was comprehensively reviewed based on the properties of zinc cysteamine.[Results]Zinc cysteine,as a complex containing cysteine and zinc,has high stability and can effectively deliver nutrients.It can not only promote the growth of animals and optimize the quality of meat and milk,but also en-hance the immunity of animals.Zinc cysteine can promote the synthesis of protein and the development of ani-mal bone by regulating the balance of redox in animal bodies,effectively improving the production perfor-mance of animals.However,there are still issues including the optimization of dosage,the evaluation of long-term effect,and the interactions with other components in feed during the process of application.[Conclusions]Zinc cysteine is a new type of feed additive with great potential of application in animal production.However,further studies and optimization of its strategies for application are still needed,with a deep investigation of its acting mechanism,optimization of its usage and methods,and efforts to develop new derivatives.The fields of applying Zinc cysteine in animal husbandry need to be expanded by combining with modern biotechnology.
