SEVERAL FACTORS INFLUENCING WORM INFECTION IN PIGS IN SOME LOCALITIES IN THE RED RIVER DELTA

Abstract

To determine factors influencing  worm infection in pigs in some localities in the Red River Delta. An investigation was undertaken in the communities of Tan Chi (Tien Du - Bac Ninh), Quang Trung (Kien Xuong - Thai Binh), Hai Chau (Hai Hau - Nam Dinh). Fuileborn method was used to test pig feces samples. Results showed that housing facilities and feed used in those localities were not hygienic. Consequently the incidence of pigs infected with worms were quite high (Tan Chi 80,4%, Quang Trung 64,0%, Hai Chau 60%). Some factors causing high incidences of worm infection in pigs were feces kept on farm, rough floors, wet floors, use of polluted water to wash vegetables and clean farms, irregular drenching of  worms for pigs.
