辽宁地区猪腹泻类疾病发病及免疫情况调查

Investigation of Pig diarrhea diseases and immune condition in Liaoning area

为调查猪腹泻类疾病在辽宁地区的发病流行情况,笔者对辽宁省14个市的280个养殖场户猪只的发病与免疫情况进行了调查,对相关数据进行统计分析,结果显示调查的280个场户的综合免疫场数为150个,免疫率为54%,发病数为11 097,死亡数为7 797,死亡率为70%。病原微生物感染导致的死亡率为53%,管理因素所致的死亡率为31%,营养因素导致的死亡率为9%,其他原因导致的死亡率为7%。因此,目前辽宁省造成仔猪腹泻病的主要因素还是病原微生物的感染,而其病原主要为PEDV、PRV。

The results showed that the number of immunized farm households was150, the immunization rate was 54%, and the incidence was 11 097, the mortality was 7 797, the mortality rate was 70%, respectively. The mortalities caused by pathogenic microorganisms, management, nutrition and other factors were 53%、31%、9% and 7%. Therefore, currently pathogenic microorganisms are the main factor that causes Pig diarrhea diseases, and the main pathogens are PEDV and PRV.
