摘　　要：冬春交替时期虽然外界温度逐渐回升,但总体温度依然较低,外界环境很容易发生突变,倒春寒发生率相对较高,养殖环境中的应激因素逐渐增多,如若不能做好猪舍的防寒保暖工作,易造成冷应激刺激,导致猪的抗病能力逐渐降低,造成多种传染性疾病的暴发流行,使养殖场的发病率、死亡率呈现逐渐升高的态势。为有效防范冬春季节猪疫病的传播流行,需从具体的发病原因角度入手,并以此为基础构建针对性的防范方案,注重提高猪的身体抵抗能力,将各类传染性疾病的发生流行率降低到最小程度,确保生猪养殖安全。该文探讨当前生猪疫病发生流行的特点,明确冬春季节猪疫病发生的原因,并提出预防措施。In the alternation period of winter and spring,although the external temperature gradually rises,the overall temperature is still low,and the external environment is prone to mutations.The prevalence of reverse spring cold is relatively high,and the stress factors in the breeding environment are gradually increasing.If we cannot do a good job in cold prevention and warmth of pig houses,it is easy to cause cold stress stimulation,which will lead to the gradual reduction of pig disease resistance,resulting in the outbreak and epidemic of a variety of infectious diseases.The morbidity and mortality of aquaculture farms showed a gradually increasing trend.In order to effectively prevent the transmission and epidemic of pig diseases in winter and spring,it is necessary to start from the perspective of specific causes of disease,and build targeted prevention programs based on this,pay attention to improving the body resistance ability of pigs,reduce the occurrence and prevalence of various infectious diseases to a minimum,and ensure the safety of pig breeding.In this paper,the characteristics of the current epidemic of pig epidemics were discussed,and the causes of pig epidemics in winter and spring were clarified and the preventive measures were put forward.
