Degree of invasion of horses Parascaris equorum under different conditions of content

The significant dependence on the invasion of Parascaris equorum horses with different maintenance technologies was studied. Methods of helminthocoprooscopy revealed the spread of parascaridosis of horses kept in stable and herd conditions in the Pobeda farm in the Cheremshansky district of the Republic of Tatarstan. The high invasion of animals with herd and stable housing is apparently associated with a large contamination of horse stalls, stables, care items and the surrounding area with parascaride eggs. The maximum parasiticidal infection of horses was established with stable maintenance. As a result of the studies, it was found that the maximum extent of invasion (EI) of horses in the examined farm with stable technology of keeping was 42.8 % and herd content was 37.5 %. The intensity of invasion (II) by parascarides varied from 23.7±3.4 to 77.3±5.6 ind. eggs in 1 g of feces, depending on the technology of maintenance.
