초록
Among 2,373 slaughtered pigs examined for one year(March 1995 to February 1996), 1,899 pigs had visible pulmonary lesions. Prevalence rate of pulmonary lesion was examined by pathological techniques according to rearing and health managements of pig farms. The results were as follows : 1. Prevalence rate of pulmonary lesion in all-in/all-out flow farms(71.9%) was lower than that in continous flow farms(85.2%). 2. Prevalence rate of pulmonary lesion in non-infected farms with Aujeszky's disease virus and/or porcine reproductive and respiratory syndrome virus(74.4%) was lower than that in infected farms(85.5%). 3. During winter, prevalence rate of pulmonary lesion in farms with cold-control facilities(83.2%) was lower than that in farms with poor cold-control facilities.
