Research Progress on Follicle Selection and Atresia Regulatory Mechanism in Chicken(Gallus gallus)
The number and proportion of developmental follicles and atretic follicles in different stages of chicken ovary are related to egg production performance.A well-organized order of follicles is very important to improve egg production and maintain the continuity of egg production.In this paper,the physiological phenotypic changes during follicle selection and atresia in chickens were analyzed and the main regulatory mechanisms were summarized,and the roles of granulosa autophagy,apoptosis and inflammation in follicular atresia were discussed.The future research direction and suggestions are put forward,which has important reference value for analyzing the genetic mechanism of chicken egg laying traits.
