Abstract

Common problems of reindeer husbandry are infectious and invasive diseases, of which anthrax and edemagenosis cause the greatest economic damage. The main method of prevention of these diseases is timely vaccination and treatment of animals with antiparasitic agents. However, it is difficult to carry out frequent veterinary manipulations in reindeer husbandry, which is due to the specifics of the industry. In order to reduce veterinary treatments against anthrax and edemagenosis, the possibility of using a mixture of aversectins with a vaccine strain of the causative agent of anthrax was evaluated. To do this, a medicinal composition was prepared, consisting of the aversectincontaining drug «Farmacin» and the anti-ulcer vaccine strain 55 VNIIVViM, by mixing 100 ml of an antiparasitic agent with 50 doses of the vaccine. The drug was administered to adult reindeer by intramuscular injection at the rate of 1,0 ml of the drug per 50 kg of body weight. Preventive treatment was carried out in September. 10 animals participating in the experiment were continuously monitored for 14 days, the main physiological parameters were determined and the dynamics of the morphobiochemical composition of blood was studied. During the experiment, it was found that the composition under study does not cause any pronounced local and general reaction of the body to its introduction, and the morphobiochemical composition of the blood with the expiration of time has no reliable transformations. Production tests carried out on 300 deer showed that the introduction of the drug provides 100% therapeutic and preventive effectiveness in edemagenosis and contributes to the formation of intense immunity against anthrax. Thus, the developed method of prevention of these diseases makes it possible to optimize veterinary manipulations in reindeer husbandry.
