| Abstract | ||
| Gastrointestinal nematodes are of major concern to the productivity and health for small ruminants, they cause severe symptoms such as watery diarrhea, anorexia, weight loss and even death of affected animals. The present study was carried out for microscopical identification of gastro intestinal nematodes in sheep and goats by floatation technique and faecal culture and determines their prevalence and seasonal incidence. Faecal examination was carried out on 83 sheep and 38 goats of different ages, sex and localities, the infection rate among sheep and goats was (44.57%) and (18.42%) respectively. The seasonal incidence of nematodes was recorded. By floatation technique, the recorded species in sheep were as follow; eggs of Trichuris ovis (2.40%), Haemonchus contortus (38.55%), Strongyloides papillosus eggs (36.14%), Bunostomum trigoncephalum eggs (2.40%). Trichostrongylus sp. eggs (9.63%), the highest infection rate recorded during summer season followed by spring and winter season was 46.66%, 44.82% and 41.66% respectively. Regarding goats; Trichuris ovis eggs (2.63%), Haemonchus contortus eggs (7.89%). Strongyloides papillosus eggs (13.15%). Trichostrongylus sp. Eggs (5.26%), the highest infection rate recorded during winter season followed by spring and summer season with an infection rate of 25%, 22.22% and 16% respectively, the same samples were re-examined by faecal cultures and Baerman's technique, results compared, it concluded that, the combination between two method is better for concise identification than floatation technique alone, also the morphology and morphometry of recovered eggs and larvae were recorded. | ||
