Comparative study of modern acaricidal preparations for psoroptic goats in the conditions of the Caspian region of the Russian Federation

Acaricidal efficacy of domestic and foreign drugs was studied in the fight against goat psoroptes in the conditions of the Caspian region of the Russian Federation. Comparative experiments and studies have shown that among the drugs Alfamek, Aversekt-2, Meradok, Dektomax. The brightest acaricidal effect was shown by the domestic drug Meradok based on doramectin. When using the drug Aversect-2 according to the recommended doses, the full therapeutic effect is not achieved. The drug Alfamek requires re-treatment after 8-10 days to completely get rid of parasites. Doramectin, a new member of the macrocyclic lactone group, shows better ectoparasite efficacy compared to ivermectin, moreover, unlike ivermectin, the pharmacokinetic properties of doramectin ensure long-term preservation of therapeutic concentrations of the drug in the blood of animals and protect them from parasitic diseases and reinvasion for a long time - up to 25 days, while the drugs Alfamek, Aversect-2 re-invasion give only 20-22 days with double treatment. The drug Meradok when compared with a foreign counterpart Dectomax gives similar results, but significantly cheaper in price. The data obtained allow us to determine the most effective therapeutic and prophylactic drug for psorioptic goats in the conditions of the Caspian region of the Russian Federation.
