Prevalence and Dynamics of Some Gastrointestinal Parasites of Sheep and Goats in Tulus Area Based on Post-Mortem Examination

A.H.A. Almalaik, A.E. Bashar and A.D. Abakar

Abstract:
The gastrointestinal tracts of 79 sheep and 161 goats were obtained from abattoir of Tulus locality in South Darfur State in western Sudan from March, 2006 to February, 2007 and examined for the presence of gastrointestinal parasite. Seven nematode species (99.8%) and Monieza expansa (0.2%) in sheep beside, eight nematode species (99.9%) and Monieza expansa (0.1%) in goats were identified. In sheep the nematodes were, in order of prevalence: Haemonchus contortus (53.4%), Strongyloides papillosus (26.2%), Trichostrongylus colubriformis (14.7%), Cooperia pectinata (3.1%), Oesophagostomum columbianum (2.2%), Skrjabinema ovis (0.3%) and Trichuris globulosa (0.1%) while, in goats were: Strongyloides papillosus (26.5%), Haemonchus contortus (26%), Trichostrongylus colubriformis (24.4%), Skrjabinema ovis (11.6%), Oesophagostomum columbianum (9.9%), Gaigeria pachyscelis (1%), Trichuris globulosa (0.6%) and Cooperia pectinata (0.1%). The intensity of the parasite infections was light to moderate. The mean worm burden was 497.3 and 472.4 for sheep and goats, respectively. The total worm burden was least during the dry season and increased gradually during the rainy season. Total worm burden was shown to have association with season and sex in goats but not in sheep while no association was observed between total worm burden and age of the animals in both sheep and goats. The effect of climatic factors on worm burden revealed a significant positive correlation with rainfall and relative humidity but not with temperature.
