Progress in the Application of New Breeding Technologies in Sheep Production
Sheep belong to seasonal estrus,which is anestrus for most of the year.With the continuous development of sheep industry,the problems of low reproduction rate,slow population genetic improvement and lack of estrus have become important factors restricting the development of sheep industry.Estrus synchronization and artificial insemination,which can improve the efficiency of sheep reproduction,have been paid more and more attention by large-scale farms.This paper describes in detail the definition,operation method and technical flow of estrus synchronization,artificial insemination and laparoscopic insemination,the advantages and disadvantages of the technology,the factors affecting the technology and the prospect of application,in order to provide relevant technical support for farmers and herdsmen,solve the reproductive limitations of sheep,reduce the difficulty of production management,improve the economic benefits of sheep breeding,and promote the development of sheep breeding industry.
