Investigation of the epidemics of porcine parvovirus in Ningxia.

Abstract

In a survey of 359 blood samples taken at random from 8 pig farms in 8 counties of Ningxia, tested by the haemagglutination inhibition test, 291 (81%) were positive. Some samples from all herds were positive, with prevalence on the farms ranging from 52% to 100%. The number of abortions, stillbirths, and mummifications were greatly reduced by porcine parvovirus vaccination campaign in 1991.
