Horse intestinal helminthiasis is widespread. The helminth fauna of horses differs in different areas. Intestinal helminthiasis affects most horses of the livestock at stud farms, especially with herd keeping
The article presents a study of the diversity of the helminth fauna of horses in the city of Kaluga. Microscopically examined 60 fecal samples taken from the stalls of 30 sports horses aged 2 to 15 years. Samples were taken twice, the first time on 06/17/2019, the second time on 09/27/2019. Helminth-endoscopic examinations for the diagnosis of intestinal helminthiasis were performed by the Fulleborn method with a solution of sodium salt and by the Kotelnikov-Khrenov method with ammonium nitrate. Then, before crystallization, each drop was examined under a microscope with a magnification of 400.
As a result of the study, eggs of the helminth Strongylus equines were found in 49 samples out of 60. The eggs found had a typical oval shape, measuring 0.07-0.09 x 0.04-0.05 mm. The shell was two-contour, gray in color. In 34 samples from 60 subjects, immature eggs of Parascaris equorum were found. Eggs are rounded in shape, with a diameter of 0.1 mm. The shell of the eggs was dense, dark brown in color. On the territory of the city of Kaluga, horses are found to have intestinal diseases.
