Distribution of parascaridosis in horses with a mobile-stable and stable content

Given the high invasion of horses with parascarids, helminthological studies have been conducted, the purpose of which was to study the dependence of the distribution of parascariosis in horses on the technology of keeping animals. In the experiments, 129 samples from 89 different mature groups of horses killed at slaughter points and dead animals at cattle cemeteries of the farm in Novosheshminsky district of the Republic of Tatarstan were used. To isolate parascaride, feces were taken directly from the rectum and examined with the improved Kotelnikov-Khrenov method with a solution of ammonium nitrate. In the helminthoscoproscopic examinations, standard centrifuge tubes with a volume of 10 cm2 and scorological cups (50 cm3) were used. The number of parascarid helminth eggs in 1 g of feces was determined using a VIGIS counting chamber. The species composition of helminths was determined on the basis of a study of the morphology of eggs. During the helminthological dissection of the intestines of horses, the number of parascarids was counted, the extensiveness (EI,%) and the intensity of invasion (AI, spec...
