This study was carried out to determine the prevalence of gastrointestinal helminths in cattle in Ağrı center
and its districts. Approximately 30-50 gr of stool samples were taken from the rectum of each cattle belonging
to the family businesses and placed in stool containers in different settlements in Ağrı center and Patnos,
Doğubeyazıt, Diyadin, Eleşkirt, Taşlıçay, Tutak and Hamur districts, were brought to Van Yüzüncü Yıl University
Faculty of Medicine Department of Parasitology Research Laboratory. After the stool samples were dissolved
in tap water, they were filtered with the help of a plastic tea strainer. The resulting filtrate was placed in
centrifuge tubes and centrifuged at 1800 rpm for three minutes. The supernatant collected at the top of the
tubes was removed, leaving 2-5 ml of liquid at the bottom of the tubes. Preparations were prepared from the
remaining liquid and examined under a light microscope. Helminth eggs were found in 120 (52.2%) of 230
cattle whose stool samples were examined, and more than one helminth species was detected in 36 (15.7%)
of these cattle. In the study, Trichostrongylus spp. in 51 (22.8%) samples, Toxocara vitulorum in 25 (10.1%),
Fasciola hepatica in 19 (8.3%), Ostertagia spp. in 11 (4.8%), Trichuris spp. in eight (3.5%) and Dicrocoelium
dendriticum was found in five (2.2%) samples. A high rate of gastrointestinal helminths was found in cattle in
Ağrı and its districts. These parasites, which cause significant decrease in productivity and even death in cattle,
are of great importance, and it is extremely important to periodically control the animals for intestinal
parasites and to treat parasitized animals, especially in Ağrı province where pasture livestock is common.
