Situation of gastrointestinal parasites infection in dairy cattle in Cu Chi district, Ho Chi Minh City

Abstract

Study was conducted to determine the prevalence and the intensity of gastrointestinal (GI) parasite infection in dairy cattle in Cu Chi district, Ho Chi Minh City and to analyse the factors such as: commune, herd level, age, sex and body condition score affecting GI parasite infection. A total of 300 fecal samples
of dairy cattle belonging to the Holstein Friesian hybrid breed, regardless of gender, age from 2.5 months old to 7 years old were collected and examined by using standard qualitative and quantitative methods to determine GI parasites based on the morphology and size of the helminth eggs, coccidiosis
oocysts. The studied results showed that there were 179 out of 300 fecal samples (59.7%) positive for one or more species of GI parasites. The prevalence of Paramphistomum spp., Trichostrongylus spp. and Eimeria spp. in the positive fecal samples with these parasites was 32%, 28% and 23.67%, respectively. The intensity of parasitic infection was moderate. The factors of commune, age, sex significantly affected to the prevalence of Eimeria spp. (P<0.05). Body condition score significantly affected to the prevalence of Paramphistomum spp. (P<0.05).
