Abstract

Abstract: To study the epidemiology state and factor of the Porcine Reproductive and Respiratory Syndrome (PRRS) in Henan Province, as well as putting forward defending advise. This experiment used questionnaire investigation, locale investigate and sample detection. The results suggested that the PRRS occurred in most county of Henan Province, and no significance during county. The PRRS often occur in the Spring and Winter, the proportion of the disease swines of 35~70 days is highest (41%). The samples of 165 hogpen in Henan Province were detected, the result showed that the sample of 65 hogpen was the positive; the positive ratio is 34.4%. It suggested that the PRRS in Henan Province was very serious, to establish all kinds of steps to positively prevent and cure.
