STUDY ON EPIDEMIOLOGICAL OF TRICHOCEPHALUS SUIS IN PIGS IN THAI NGUYEN AND BAC KAN PROVINCE

Abstract

To assess the situation of Trichocephlus nematode infection in pigs in Thai Nguyen and Bac Kan provinces, we have applied a non-comprehensive method of surgery to examine 416 pigs raised in districts in Thai Nguyen and Bac Kan provinces, results showed that there were 141 pigs infected with Trichocephalus suis nematode, accounting for 33.89%, the infectious intensity was generally from 6 to 1584 worms/pig. Examination of feces of 3600 pigs in the two provinces above, with 1134 pigs infected with Trichocephalus suis nematode, at rate of 31.50%, infected pigs from mild to severe intensity was 57.58% to 13.49%, respectively. Age, animal husbandry method, season and veterinary hygiene status influenced significantly on the prevalence and intensity of Trichocephalus suis nematode infection in pigs.
