中文摘要:

      文章综合阐述了雌性动物主要生殖激素、卵巢的周期性发育和“下丘脑-腺垂体-性腺轴”对母牛生殖过程的调控机制研究进展。“下丘脑-腺垂体-性腺轴”在调节母牛青春期第二性征发育、发情周期与妊娠分娩上发挥着重要的作用,通过研究“下丘脑-腺垂体-性腺轴”的调控机制,有助于研究者发现母牛繁殖性能下降的内分泌原因,帮助筛选和治疗繁殖障碍的繁育母牛。文章为繁育母牛屡配不孕机制研究和治疗提供理论依据。

英文摘要:

      This article summarizes the progress of research on the main reproductive hormones in female animals, the cyclic development of ovaries and the mechanisms of the "hypothalamus-pituitary-gonadal axis" regulating the reproductive process in female cows. "The hypothalamic-pituitary-gonadal axis plays an important role in regulating the development of pubertal secondary sexual characteristics, estrous cycle and pregnancy and delivery in cows. The study of the hypothalamic-pituitary-gonadal axis will help researchers to identify the endocrine causes of the decline in reproductive performance of heifers, and help to screen and treat breeding heifers with reproductive disorders. This article provides a theoretical basis for the study and treatment of infertility in breeding heifers.
