A total number of summary 520 feces and 74 excreta samples were collected from pig farms located in northern, central, southern and eastern Taiwan (including prefectures, Taipei, llan, Hawlein, Kaushung, Chayi and Yunlin). The precipitation method and floating method were carried out on each sample for the examination of parasitic eggs or oocysts, followed by calculation of them using McMaster counter plated. The results were summarized as follow:
1. Fecal contamination of porcine coccidia was most evident to be 17 .3% (90/ 520), followed by Trichuris suis, 7.7%(40/ 520), Oesphagostomum dentatum, 3.7% ( 19/ 520), Ascaris suum, 3.3%( 17 / 520), Strongyloides ransomi, 3.1 %( 16/520), Ascarops spp., 1.2%(6/520). Last evidence was Rhabditis suis that was 0.38%(2/520).
2. Five out of 74 excreta (6.8%) were found to be contaminated by Coccidia, only one of them could be sporulated.
3. Any kind of parasite eggs of oocysts could not be found in the fishing pond fed by the porcine excreta.
