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 Seasonal Prevalence of Gastro-Intestinal Helminth Parasites of Goats (Capra sp.) of Shivraj Municpality-13 Kapilvastu, Nepal(Department of Zoology, 2015) Tripathi, Rabindra PrasadGoat (Capra sp.), being an important source of meat in Nepal. This species is greatly affected by the helminthes parasites. The current study was carried out to observe the seasonal prevalence of intestinal parasites with sedimentation and flotation techniques. The samples were collected and examined for the study periods. The overall prevalence of helminth parasite during winter, 58 (54.71%) infection and summer 86 (81.13%) infection. Winter 13(12.26%) infection were caused by trematodes, 7 (6.66%) by cestodes and 38 (35.84%) nematodes. Summer 19(17.92%) infection were caused by trematodes 11 (10.37%) by cestodes and 56(52.83%) nematodes. The prevalence percentage of identified genera of trematodes were Dicrocoelium sp. (3.47%), Fasciola sp. (15.97%) and Paramphistomum sp. (2.77%). The difference in the prevalence of different genera of trematodes during winter and summer were not found statistically insignificant (χ2= 1.325, p 0.250). Among cestodes the genera identified with their prevalence percentage were found to be Moniezia sp. (2.77%) and Taenia sp. (9.72%). The difference in the prevalence of different genera of cestodes during winter and summer were not found statistically insignificant (χ2= 2.186, p 0.139). Similarly the genera included in nematodes are Toxocara sp. (16.66%), Strongyl sp. (1.38%), Bunostomum(2.77%),Capillaria(4.86%),Chabertia(4.16%),Dictyocalus(4.86%), Cooperia(2.08%),Heamonchus(3.47%),Oesophagostomum(8.33%),Nematodirus(0.69%),Ostertagia(1.38%),Strongyloides(6.25%),Trichuris(5.55.%),Trichostrongylus(4.86%). Mixed infection was observed in 54 (50.94%) winter and 80(75.47%) summer season. Altogether 134 (63.20%) mixed infection were detected. The difference in the prevalence of helminth parasites during winter and summer seasons were found statistically significant (χ2=6.193, P<0.013, d. f. = 1)Item Seasonal Prevalence of Helminth Parasites in Buffaloes of Pokharathok VDC in Arghakhanchi(Department of Zoology, 2012) Devi, RadhaBubalus bubalis (buffalo) is one of the important species of domestic livestock in Nepal.This species is greatly affected by the helminthes parasites. The current study was carried out to find out the seasonal prevalence of intestinal helminth parasites in buffaloes. Sedimentation and floatation both technique were used during the detection of helminth parasites. The samples were collected in two seasons i.e. during summer and winter. A total of 250 stool samples were collected and examined during the study period i.e. 120 samples in winter and 130 samples in summer. The overall prevalence of helminth parasites during winter were (45.83%) and that in summer season were (88.46%). A huge difference in the prevalence of helminths parasites in the both seasons were observed. During winter season the buffaloes were found to be infected with trematodes 31.66%, cestodes 10% and 32.5% nematodes. Likewise 67.69%, 11.53% and 56.15% of infections were caused by Trematodes, Cestodes and Nematodes respectively during summer season. The overall prevalence percentage of identified genera of trematodes are as follows; Fasciola 29.41%, Paramphistomum 11.76%, Dicrocoelium 12.94%, Schistosoma38.23%, Gastrothylax 2.35%, Fischoederius 1.17%, Ornithobilharzia 0.58% and Skrjabinema 5.29% respectively.Among cestode, the overall prevalence percentage of identified genera was found to be Moniezia 15.88% .Similarly the genera included in nematodes are Strongyloides 13.52%, Trichostrongylus 5.88%, Toxocara 34.11%, Ascaris 18.23%, Chabertia 1.76%, Trichuris 5.88%, Dictyocaulus 0.58%, Oesophagostomum 1.17%, Capillaria 1.17%, Haemonchus 1.76%, Ostertagia 2.94%, and Cooperia 0.58%. Single infection was found in 40% samples during winter and during summer it was found in 14.78% samples. Mixed infections was observed in 60% and 85.21% in the samples of winter and summer respectively.The difference in the prevalence of helminth parasites during both seasons were found statistically significant. ( χ² = 740.15, P<0.05, d.f. =21).
