Item Epidemiology of Gastrointestinal Helminths in Goats of Banke , Nepal(Department of Zoology, 2012) Neupane, Om PrakashCapra hircus (goat) is one of the most important species of domestic livestock in Nepal.This species is greatly affected by the helminth parasites. The current study was carried out to determine the prevalence of Gastointestinal Helminths in goats of Banke. The fecal samples were examined qualitatively by differential floatation and sedimentation technique and quantative (egg per gram) examination was done by Stoll’s counting method. A questionnaire survey was conducted among 30 randomly selected goat owners regarding management practices and use of anthihelmintecs. A total of 315 fecal samples of which 165 in post rainy season and 150 in winter season were examined to determine the prevalence and intensity of helminths infection in goats. The study revealed 208 fecal samples out of 315 samples (66.03%) with significant EPG. The prevalence was higher in wet season (75.75%) than in dry season (55.33%) and was statistically significant (2=5.311, P<0.05).The most common parasites encountered were Strongyloides (24.39%), Haemonchus (20.97%), Moniezia (20.52%), Trichostrongylus (19.45%), Trichuris (17.65%), Fasciola (17.25%), Nematodirus (11.12%), Paramphistomum (9.28%), Oesophagostomum (8.91%),Ostertagia (8.35%), Chabertia (7.65%), Dicrocoelium (5.45%) and Capillaria (2.15%). Altogether 13 genera of helminth parasites were found in present study among them one was cestode (Moniezia), 3 were trematodes (Fasciola, Paramphistomum and Dicrocoelium) and 9 were nematodes. This study showed 45.67% trematode infection, 24.51% cestode infection and 82.21% nematode infection. The prevalence of helminths infection reflects a higher occurrence in the adults (70.54%) followed by the kids (63.38%) with young goats (62.60%) having the least. The prevalence was highest in Mahadevpuri (69.52%) followed by Khaskushma (68.57%) and least in Rajhena (60.01%). Out of 208 (66.03%) positive samples, 158 (75.95%) positive samples were found to have mixed infections.Most of the farmers are unaware of helminths parasite problems. There should be provision of adequate and appropriate control strategies and awareness programs for farmers to enhance the goat farming and increase productivity.Item A Study On Intestinal Helminth Parasites of Buffaloes Brought To Satungal (Kathmandu) For Slaughter Purpose(Central Department of Zoology Institute Of Science and Technology Tribhuvan University Kirtipur, Kathmandu Nepal, 2007) Mukhia, GouriBubalus bubalis (buffalo) is one of the leading species of domestic livestock in Nepal. The helminthic diseases are most varied and of common occurrence in buffaloes. Present study was carried out to find the prevalence of intestinal helminth parasites in 262 stool samples of buffaloes during July to August 2006.Both sedimentation and floatation technique were used for the detection of helminth parasites. A total of 262 stool samples were collected during the study period and examined. The overall prevalence of helminth parasites was found 83.96%. There is significant difference in the prevalence of trematode, cestode and nematode infections among buffaloes. The parasitic infection of trematode was 90.90%, cestode 14.54% and of nematode 49.09%. Trematodes, Dicrocoelium lanceatum and Ornithobilharzia turkestanicum are reported for the first time from Nepal. However, no work regarding these species have been reported from any host. Although trematode Skrjabinema ovis, Fischoederius elongatus and nematodes, Chabertia ovina, Dictyocaulus sp and Capillaria sp has been reported from various hosts sheep, cattle and goat but not reported from buffalo. So, S. ovis, F. elongatus, C. ovina, Dictyocaulus sp. and Capillaria sp. are reported for the first time from the host buffalo in Nepal. The trematode genus identified with their prevalence percentage are as follows; Fasciola sp. 32.06%, Paramphistomum sp. 15.64%, Dicrocoelium sp. 20.61%, Schistosoma sp. 46.94%, Gastrothylax sp. 0.76%, Fischoederius sp 0.38%, Ornithobilharzia sp. 0.76% and Skrjabinema sp. 6.87% respectively. Among Cestode, only Moniezia species was observed with infection rate 13.35%. Nematode included Strongyloides sp. 4.19%, Trichostrongylus sp. 1.90%, Toxocara sp. 22.90%, Ascaris sp. 6.87%, Chabertia sp. 0.38%, Trichuris sp. 2.29%, Dictyocaulus sp. 0.76%, Oesophagostomum sp. 0.76%, Capillaria sp. 0.38%, Haemonchus sp. 1.14%, Ostertagia sp. 1.52% and Cooperia sp. 0.76%. Mixed infections were observed among 140 positive samples. Among trematode, Dicrocoelium lanceatum and Fasciola hepatica found to be heavily infected. In cestode, Moniezia benedeni and nematode, Toxocara vitulorum found to be heavily infected in buffaloes.
