Abstract: The paper introduces some practical and novel techniques and methods to improve reproductive performance of Tan sheep.It also presents application effects and subjects of several practical techniques such as estrus controlling,immune prolificacy and nutritional reproduction regulation.These methods were analyzed and compared.This paper proposes that different methods should be applied at different physiological status of ewes,which can shorten reproductive cycle of ewes,increase litter size,and thus increase economic benefits of Tan sheep production.
