孕酮对奶牛早期胚胎及其发育环境的影响OA
The Effects of Progesterone on Early Embryo and Developmental Environment in Dairy Cows
早期胚胎死亡是奶牛人工授精效率降低的主要原因.孕酮通过影响卵母细胞质量和调控输卵管和子宫环境,在奶牛早期胚胎发育以及妊娠建立和维持中发挥关键作用.本文总结了孕酮对早期胚胎及其发育环境的影响,评价了早期阶段补充孕酮的策略,以期为提高奶牛繁殖效率提供参考.
Early embryonic death is a primary cause contributing to reduced efficiency in artificial insemination for dairy cows.Progesterone(P4)plays a crucial role in early embryonic development,as well as in the establishment and maintenance of pregnancy in dairy cattle,by influencing oocyte quality and regulating the environment of the oviduct and uterus.This paper summarises the effects of P4 on early embryos and their developmental environment,and evaluates strategies for early-stage progesterone supplementation,with the aim of providing guidance for enhancing reproductive efficiency in dairy cows.
