摘要
[目的 ]掌握猪腹泻在规模猪场(年出栏>1000头)的流行情况和主要病原,分析疫病发生的风险因素。[方法 ]采用横断面研究方法,选取江西、河南、湖南、四川和广西5个省、区407个规模猪场,开展了问卷调查、现场调查和实验室检测。[结果 ]调查发现腹泻的场流行率为71.99%,腹泻的发生率与猪场规模呈负相关(R2=0.87),不同种类猪的流行率不同,母猪、育肥猪、保育猪和哺乳仔猪发生腹泻的流行率分别为3.48%(95%CI,2.24%-4.96%)、2.4%(95%CI,1.35%-3.63%)、12.78%(95%CI,10.25%-15.41%)和33.80%(95%CI,31.02%-36.86%)。多重logistic回归分析结果表明,腹泻的发生与饲养年限、车辆进场消毒以及产房温度等因素有关。
A cross-sectional study was carried out for large scale pig farms（over 1000 pigs per year） to learn the prevalence of porcine diarrhea in China. 407 pig farms in Jiangxi,Henan,Hunan,Sichuan and Guangxi provinces were randomly selected in the investigation. After a series of questionnaires,field surveys,feces collection and labora-tory detection,the herd prevalence was 71.99% with a negative correlation between the occurrence of diarrhea and the size of pig farms. The attack rate was 3.48%,2.4%,12.78% and 33.80% respectively in sow,fattening pigs,breed-ing pigs and piglets. Using multi-logistic regression analysis on the risk factors of diarrhea,a mathematical model of diarrhea was constructed,indicating that the occurrence of diarrhea had a close relationship with pig age,disinfection status and the temperature in delivering room.
