A Study on intestinal helminth parasites of goats ( (Capra hircus) brought to Khasibazar, Bagbazar (Kathmandu) for slaughter purpose

Abstract

A total of 202 stool samples of Capra hircus (goat) from Khasi bazaar (Bag bazaar) Kathmandu were microscopically examined to identify the prevalence of intestinal helminth parasite. Both sedimentation and flotation technique were used for the detection of helminth parasites. Out of total 202 samples, 161(79.70%) samples were found positive for more than one helminthes. The overall prevalence of different genera of helminth results statistically significant in goats (χ2 =101.49, P<0.05, d.f. =17). There is significant difference in prevalence of trematode, cestode and nematode infection among goats. The infection with trematodes was 5.94%, with cestodes 4.45%, with nematode 69.30%.

The trematode genera identified with their prevalence percentage was found to be Fasciola 3.46% and Paramphistomum 2.47% The difference in the prevalence of different genus of trematodes result statistically significant (χ2=0.332, P>0.05, d.f. =1). Among cestodes, the prevalence percentage of identified genera was found to be Moniezia 1.48%, Taenia 2.97%. The difference in the prevalence of different genus of cestode result statistically significant (χ2 = 1, P>0.05, d.f. =1) Nematodes include Strongyloides 3.46%, Haemonchus 13.36%, Chabertia 4.95%, Oesophagostomum 11.88%, Trichuris 7.42%, Ostertagia 5.94%, Trichostrongylus 2.97%, Nematodirus 2.97%, Cooperia 2.47%, Dictyocaulus 1.48%, Dioctophyma 1.48%, Capillaria 5.94%, Bunostomum 0.99%, Oxyuris 0.99%. The difference in the prevalence of different genus of nematodes result statistically significant (χ2 =84.37, P<0.05, d.f. =13). Single infection was observed among 38 samples and highest due to Haemonchus. Mixed infections were observed among 123 samples positive samples. Among Trematodes the heavy infection was found due to Fasciola, among cestode, due to Moniezia and among Nematodes, due to Oesophagostomum.
