Summary. Sheep breeding in the Caspian region, in particular, in Dagestan Republic, is a traditional branch of meat and wool production. Its profitability depends on preventive measures against invasive diseases. A significant factor that reduces the productivity of sheep are diseases with skin lesions, mainly of parasitic etiology, which cause significant morphological and functional changes in the skin, as well as in the internal organs of sheep, which ultimately leads to the decrease of meat and wool productivity. Despite the antiparasitic measures being taken in the republic, no significant progress has been made in the fight against psoroptosis of the small horned cattle. The reason of this are violations of the rules, deadlines, techniques of conducting of therapeutic and preventive measures, and to a large extent the choice of modern, relevant and most effective acricidal agents against the pathogen of Psoroptes ovis. The obtained data showed that Ratox in 0.006% concentration of the active substance in the working solution of the emulsion has given the prophylactic effect against Psoroptes ovis by 25.9% higher than Diazecto at 0.025% concentration. The reinvasion period for Diazecto was 20 days, for Ratox -27 days. Newly diseased animals after 30-days-treatment by Diazecto, Ratox and water were 8, 1 and 21 sheep, respectively. These results were based on the difference between the active ingredients of the acaricidal agents that participated in the experiments, and their different degree of action on the causative agent of the disease (Psoroptes ovis).

Keywords: small horned cattle, sheep, psoroptosis, Psoroptes ovis, prevention, reinvasion, acaricides, active ingredient, Diazecto, Ratox.
