| 摘 要： | 围产期(产前3周至产后3周)是奶牛内分泌和代谢发生巨变的时期,此时期奶牛经历了不同程度的能量负平衡,可影响其产后生产性能和对疾病的易感性.本文综合阐述了围产期奶牛的生理特点及营养代谢特征,为以后围产期奶牛的饲养管理及科学研究提供新的思路.

| Abstract: | The periparturient period of dairy cows, namely a transition period from three weeks before calving to three
weeks after calving, is characterized by endocrine and metabolic changes to accommodate parturition and lactation. Dairy
cows experience some degree of negative energy balance during this period, which may affect the susceptibility of cows
to metabolic disorders and infectious diseases, as well as to milk production. This paper summarizes the physiological,
nutritional and metabolic characteristics in periparturient dairy cows. The aim of this review is to offer a new idea for the
raising and management of dairy cows and relevant research. |
