| 摘 要： | 在奶牛围产期,许多奶牛因能量负平衡(NEB)无法适应代谢、内分泌和生理的巨大变化,引发酮病和脂肪肝,影响奶牛产后恢复,造成严重的经济损失。奶牛分娩、产犊的应激性大,产奶量增长迅速,采食量降低,饲养中能量供应不足是此阶段存在的主要问题。为获得更高品质的肉制品以及更高的养殖收益,文章针对调控围产期NEB展开综述,以期为生产中实际应用提供参考。

Research progress on regulation of negative energy balance in ruminants during perinatal period |

| Abstract: | During the perinatal period of dairy cows, many dairy cows cannot adapt to the great changes in metabolism,endocrine and physiology due to negative energy balance(NEB), causing ketosis and fatty liver, affecting the postpartum recovery of dairy cows and causing serious economic losses. The stress of parturition and calving of dairy cows is high,milk yield increases rapidly, and feed intake decreases and energy supply is insufficient in feeding are the main problems in this stage. In order to obtain higher quality meat products and higher breeding income, the article reviews the regulation of perinatal NEB, to provide referece for practical application in production. |
