Sheep farming is an important segment of the livestock sector in Turkey. However, low meat, milk, leather and wool production due to various parasitic diseases has adversely affected this sector. This study was carried out by using stool and tissue samples collected from 300 sheep registered with the Provincial Directorate of Agriculture and Forestry in Iğdır, Turkey. Stool samples were collected using native, flotation and sedimentation methods to diagnose common parasites. In addition, parasitic diagnoses were strengthened with the migration paths of parasites and the presence of cysts as a result of macroscopic examination of the liver and lungs of sheep slaughtered in the slaughterhouse. From the data obtained, the prevalence and material damage and loss of workforce of parasites were determined using appropriate statistical programs. Fascioliasis 16.7%, Nematodirosis 20% Echinococcosis 29% Dicrocoeliasis 32% varied. It was concluded that the parasite population is high in sheep in Iğdır province, Turkey. Accordingly, attention was drawn to the issue of necessary protection and controls.

Objective: This study was carried out to determine the distribution of digestive system parasites in horses in İpekyolu, Tusba, Özalp, Saray and Gürpınar districts in Van between June 2019 and May 2020. Materials and Methods: Materials of this study consist of a total of 95 horse stool samples, 58 male and 37 female, from different races, ranging in age from 1 to 12 years. Results: Various parasitic infections were detected in 65 (68.42%) of 95 horses examined by stool examination. While 55 of 65 infected horse stool samples were infected with a single species, it was determined that stool samples of 10 horses were infected with two species. In infected horses, at most Strongylidae spp. (44.21%) were detected followed by Parascaris equorum (11.57%), Eimeria leuckarti (6.31%), Anoplocephala spp. (5.26%), Oxyuris equi (4.21%), D. dendriticum (3.16%), and Fasciola spp. (4.21%). When the infected horses were evaluated according to age groups, parasitic infections were detected in 34 (35.79%) horses aged 8 years and above, 29 (30.53%) between the ages of 5-7 and 12 (12.63%) between the ages of 1-4. When the infected horses were evaluated according to gender groups, parasitic infections were found in 38 (65.51%) of 58 male horses and 27 (72.92%) of 37 female horses. Conclusion: As a result, in this study, it was determined that the horses in the Van region were infected with various parasite species. In the study, helminth infections were found more frequently, and it was predicted that it should be combated with anthelmentics, taking into account the development of resistance against these parasites.
