Evaluation of trichostrongylidae parasites infestation of Ghezel sheep in East Azerbaijan Province using fecal eggs test

 Economical production of sheep is reduced by gastrointestinal parasites; and they can also be transmitted to humans. The present study was carried out to determine the gastrointestinal nematode parasites fauna and infestation rate in Ghezel sheep of East Azerbaijan province and stool samples were examined for helminthes infections. In this study, 120 lambs with 4-6 months’ age were selected from 6 herds (20 lambs from each herd). Fecal samples were collected directly from the rectum of lambs and parasites were counted by Clayton Lane method. The number of counted parasites eggs of Nematodirus, Marshallagia marshalli, Haemonchus contortus and Trichostrongylus were 39, 24, 23 and 14 percent respectively. Due to the contamination of sheep, control and treatment measures should be carried out and further research is recommended regarding prevention and control of infestation.
