摘要
Abstract
Objective]To evaluate the prevalence of piglet viral diarrhea(PVD)in large-scale pig farms in Guangdong province and analyze the related risk factors of PVD outbreaks.[Methods] 197 scale pig farms were investigated from December 2013 to March 2014 and then a cross-sectional study was conducted by logistic regression analysis.[Results] The prevalence rate of PVD at the farm level was 48.55%(95%CI:42.27%~56.21%). Four factors including herd size(OR=1.340,P=0.020),the behavior of visitors entering the breeding area(OR=4.740,P=0.007),the distance to roads above the county level(OR=0.389,P=0.008)and the bio-safety disposal of diseased and dead pigs(OR=0.244, P=0.035),were associated with prevalence of PVD. Multivariate logistic regression analysis showed that the behavior of visitors entering the breeding area(OR=5.003,95% CI:1.555~16.096,P=0.007)was the risk factor of PVD outbreaks. Immunization with the porcine epizootic diarrhea and transmissible gastroenteritis(PED+TGE)vaccines (OR=2.012,95% CI:1.035~3.912,P=0.039),bio-safety disposal of diseased and dead pigs(OR=0.306,95%CI:0.080~1.175,P=0.084),distance to roads above the county level(OR=0.530,95% CI:0.080~1.175,P=0.090) might be confounding factors.[Conclusion] The entry of visitors was confirmed as an important risk factor of PVD outbreaks,which indicated the importance of bio-security measures for PVD prevention and control.关键词
