能量负平衡影响奶牛卵泡发育的机制OA北大核心CSTPCD

Negative energy balance(NEB)is a metabolic disease which often occurs in cows during the early postpartum lactation period,and the NEB status will be reached when the energy intake is not sufficient to meet the energy consumption.Cows in NEB status leads to the increase of cow disease rate,decrease of pregnancy rate,and decrease of production performance,which brings great economic losses to intensive dairy production.With the wide application of molecular and histological techniques,the mechanism of NEB effect on bovine follicular development in early lactation of cows has been further revealed.This paper reviewed the research progress related to the molecular mechanism of NEB on bovine follicular development in early lactation of dairy cows according to the studies in recent years and made an outlook,aiming to provide reference for the theory of reducing the adverse effects of NEB on the reproductive performance of dairy cows.
