中文摘要:
      广义的围产期是指母牛产前2个月至产后2个月这4个月的时期,包括干奶期和泌乳前期的大部分时间。侠义的围产期是指产前3周至产后3周这42 d的时期。母牛围产期面临难产、胎衣不下、子宫炎等感染性疾病和低血钙、酮病和脂肪肝等营养代谢病的困扰,营养代谢病引起的产后掉膘严重危害繁殖性能,大大提高了母牛的淘汰率。本文对母牛围产期营养调控技术研究进展进行了综述,旨在为相关人员降低母牛疾病发病率提供理论基础。
英文摘要:
      The broad term perinatal period refers to the 4-month period from 2 months before birth to 2 months after birth, which includes most of the dry and pre-lactation periods. The perinatal period of chivalry refers to the period of 42 days from 3 weeks before to 3 weeks after birth. In the perinatal period, cows are faced with the problems of Dystocia, fetal retention, cervicitis and other infectious diseases, as well as nutritional metabolic diseases such as hypocalcemia, ketosis and fatty liver, has greatly increased the culling rate of cows. In this paper, the research progress of nutrition regulation technology in perinatal period of cow was reviewed, in order to provide theoretical basis for related personnel to reduce the incidence of cow disease.
