A Study on Intestinal Helminth Parasites of Goats (Capra Hircus) Brought to Khasibazar, Kalanki (Kathmandu) for Slaughter Purpose

Abstract

Capra hircus (goat) is one of the important species of domestic livestocks in Nepal. The helminthic diseases are most varied and common in goat. Present study was carried out to find the prevalence of intestinal helminth parasites in goat. Both sedimentation and floatation technique were used for the detection of helminth parasites. A total of 222 stool samples were collected during the study period (November, December-2006 and May-2007) and examined. The over all prevalence of helminth parasite was found to be 81.53%. There is significant difference in prevalence of trematode, cestode and nematode infection among goats. The infection with trematodes was 13.96%, with cestodes 8.56% and with nematodes 76.13%. Nematode genus Dioctophyma is reported here for the first time from Nepal. No work regarding this genus from other host also has been found. Cestode genus Taenia, Trematode genus Dicrocoelium and Nematode genera Oxyuris and Capillaria have been reported from various hosts like cattle, horse, buffalo, pig and poultry but not from goat. So Taenia, Dicrocoelium, Oxyuris and Capillaria are also reported here for the first time from the host goat in Nepal. The trematode genera identified with their prevalence percentage was found to be Dicrocoelium 5.85%, Fasciola 5.40% and Paramphistomum 2.70%. Among cestodes, the prevalence percentage of identified genera was found to be Moniezia 5.40% and Taenia 3.15%. Nematodes include Strongyloides 9.45%, Haemonchus 19.36%, Trichostrongylus 17.56%, Ostertagia 9.00%, Oesophagostomum 8.11%, Cooperia 4.05%, Nematodirus 5.4%, Dioctophyma 2.25%, Dictyocaulus 2.7%, Chabertia 14.86%, Oxyuris 0.9%, Ascaris 3.15%, Toxocara 1.80%, Bunostomum 0.9%, Trichuris 5.85% and Capillaria 2.25%. Single infection was observed among 51 positive samples and maximum due to Haemonchus. Mixed infections were observed among 130 positive samples. Among Trematodes, the heavy infection was found due to Fasciola, among Cestodes, due to Moniezia and among Nematodes, due to Chabertia.
