Study on Prevalence of Major Gastrointestinal Nematodes of Sheep in Wayu Tuka and Diga District, Oromia Regional State

Abstract

Aim
This study was devised to be conducted to determine the prevalence and identify the major gastrointestinal nematode parasites
based on fecal examination.
Methods
A cross-sectional study was carried out to determine the prevalence and associated factors with ovine gastrointestinal nematode
infestation by fecal examination of 384 sheep from Wayu Tuka and Diga district, Eastern Oromia regional state.
Results
Out of the total 384 sampled sheep, 169 (44.0%) had been infected with gastrointestinal nematode parasite. Haemonchus species
were the most frequently (20.8%) recovered nematode eggs followed by Trichostrongylus (13.0%) and Nematodirus (10.2%).
There was no significant difference (p>0.05) in prevalence between age groups and sex. Sheep with poor body condition had a significantly higher prevalence of gastrointestinal nematode parasite (p<0.05) than those sheep in moderate or good body condition.
There was no significant association between the gastrointestinal nematode infection in animals of different ages and sex groups.
Conclusion
The study shows that the gastrointestinal nematode parasite was a major important health problem and impact on the production
of sheep in the study area. Therefore, a detailed study should be conducted to identify the parasite at the species level and special
consideration should be taken on the management of sheep in poor body condition to reduce the burden of gastrointestinal
nematodes.
