集约化饲养羊场的疫病防治规范
Intensive Sheep Farm Disease Prevention and Control Specification

第四师77团文新荷羊场，自2016年集中饲养羊至今，羊的数量从集中最初的450只，发展到2022年1月，存栏数达到4800余只。从建场初，始终把疫病防疫工作作为羊场重点的工作来抓，做好各类疫病防治才能确保羊场的发展，减少疫病发生，认真贯彻《动物防疫法》，坚持预防为主的工作理念，提高疫病防治水平，才能提高养羊业的经济效益，是羊场健康发展的重要环节。为了避免家畜传染病的发生和流行，疫苗的广泛应用极大程度上减少了畜牧业的风险，但是，在生产实践中，不是所有牲畜接种了疫苗都能获得100%的保护，同时还有多种原因会引起保护率的降低，为此，国家对动物防疫加大了冷链体系的建设，以提高疫苗的保护率，现对疫苗保护率降低的原因作一浅谈。
Since the concentrated feeding of 450 sheep at the Wenxinhe Sheep Farm in the 77th Regiment of the Fourth Division in 2016, the number of sheep has now grown to over 4800 in Janu-ary 2022. From the beginning of the establishment of the sheep farm, disease prevention and con-trol have always been the key focus in order to ensure the development of the farm and reduce the occurrence of diseases. Adhering to the work philosophy of prevention first and implementing the Animal Epidemic Prevention Law, improving disease prevention and control levels is crucial for the healthy development of the sheep farm and improving economic benefits of the sheep industry. While the use of vaccines in animal husbandry has greatly reduced the risk of disease outbreaks, not all vaccinated animals can achieve 100% protection due to various reasons. In response, the state has increased construction of the cold chain system for animal epidemic prevention to im-prove vaccine protection rates. This article briefly discusses the reasons for the decrease in vaccine protection rates.
