韓國 在來山羊의 消化管 및 膵臟內 寄生蟲 調査 = A Study on the Parasites of Gastrointestinal Tracts and Pancreata of Korean Native Goats

다국어 초록 (Multilingual Abstract)

Present study was undertaken in order to clarify the species and infection rate of internal parasites in Korean native goats. Abomasum of 100 goats slaughtered in Daejun and abomasum, intestinal tracts, and pancreata of 40 goats slaughtered in Taegu prefecture were inspected. The parasites recovered were classified morphologically with following results.
1) A total of 7 species of parasite was identified. Their habitats and infection rates were as follows;
Abomasum-Haemonchus contortus: 20% in Taegu and 42% in Daejun, and Trichostrongylus sp. : 2.5% in Taegu and 3% in Daejun.
Small intestine-Moniezia expansa: 12.5%.
Large intesine Oesophagostomum columbianum: 27.5%, Oesophagostomum venulosum: 17.5%, and Trichuris ovis: 5%.
Pancreas-Eurytrema coelomaticum: 15%.
2) Characteristic nodule formation on the walls of cecum, colon, and ileum was observed in 5 out of 11 goats infected with Oesophagostomum columbianum. No nodule formation, however, was observable in goats infected with Oesophagostomum venulosum.
3) the maximum worm burdens of Oesophagostomum columbianum, Eurytrema coelomaticum, and Haemonchus contortus were higher (above 83) than those of the other parasites.
4) the numbers of female nematodes were greater than of male except Oesophagostomum venulosum.
