To investigate the swine parasitic infection rate, we performed centrifugal floatation method and sedimentation method between Jan. 1989. and Dec. 1989. This results are shown as follows. 1. The numbers of infection were 593 pigs in 1080, shown 54.9% of infection rate. 2. In this survey, eight species of swine parasite were detected. The percentage of Balantidium coli was 44.5, revealed hightest level. There were 14.5% in Ascaris suum and 11.8% in Oesophagostomum SP respectively. 3. In this survey, there was high rate(86.0%) of parasitic infection in the pig raised at sawdust fermantation house. This results suggest that pig maybe liable to infect parasite.
