Seasonal Prevalence of Gastro-Intestinal Helminth Parasites of Goats (Capra sp.) of Shivraj Municpality-13 Kapilvastu, Nepal

Abstract

Goat (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)
