摘要
高产奶牛繁殖力低下是世界性难题。能量负平衡(NEB)影响脂肪动员,改变血液代谢指标,诱发能量代谢紊乱及相关疾病,影响卵泡发育及子宫胚胎内环境,影响机体多种激素的分泌,损害奶牛生殖免疫机能,提高该状态下子宫疾病的易感性并诱发炎症反应,延缓产后子宫恢复,制约奶牛的繁殖性能。本文主要阐述NEB对奶牛繁殖的影响及相关机理,为奶牛生产和繁殖研究工作提供参考。
The low fertility of high yield dairy cows is a worldwide problem. Negative energy balance (NEB) affects fat mobilization,changes blood metabolism indicators,NEB affects fat mobilization,changes blood metabolism indicators,and induces energy metabolism disorders and related diseases,affects follicular development and uterine embryonic environment,affects the secretion of various hormones in the body,impairs the reproductive immunity of dairy cows,improves the susceptibility of uterine diseases in this state and induces inflammatory reactions,and delays the recovery of postpartum uterus,which restricts the reproductive performance of dairy cows. This paper mainly described the effects of NEB on the reproductive performance of dairy cows and its related mechanisms,and provided a reference for the research of cow production and reproduction.
