Abstract:

With the improvement of milk production of dairy cows, China's dairy industry chain is also continuously optimized and upgraded, making progress towards modernization, standardization and internationalization. However, the reproductive performance of high producing dairy cows is gradually decreasing, which has become a common problem faced by dairy cows related researchers. Follicle development is closely related to reproductive efficiency, and normal follicle development is a prerequisite for reproductive activities such as estrus and ovulation. During follicle development, follicular granulosa cells can interact with oocytes and theca cells to produce a variety of hormones and factors, and act as receptors for a variety of hormones and factors to affect follicular development. Therefore, this paper summarized the research on the function of follicular granulosa cells and follicular development, and focused on the role of follicular granulosa cells in follicular development and the influence of granulosa cells on oocytes, in order to provide theoretical reference for future related studies.

Key words: granulosa cells, follicle development, cows, reproductive performance, interaction
