PERSPECTIVENESS OF INDUSTRIAL ISSUES OF ANTI-CELLULAR VACCINES FOR THE HEAD-BREEDING INDUSTRY

Abstract

This article provides data on the distribution of coenurosis, the impact of this disease on the world economic status of sheep. Today this invasion is registered in many continents of the globe. According to the regions, where the sheep's number of head is up to 70% (Southern FD and North Caucasus FD), annual losses from a coenurosis reach 5–15%, which, on average, is about 1 million heads. Each head is 20 kg of meat and 3–4 kg of wool and, besides all, unaccounted expenses. A kilogram of mutton averages 300 rubles, and wool is about 200–250 rubles. These impressive figures amount to several billion rubles across the industry. At the present stage, according to many scientists and authors, the only way to solve this problem is vaccination with subsequent revaccination. Scientists in many countries around the world, such as China, Italy, Turkey, tried to tackle this problem, but studies have shown that the selected protective antigen is ineffective, which the scientists themselves do not deny. A method for immunoprophylaxis of lambs of the first year of life is proposed. Our experiments, carried out for 25–30 years on the prevention of this disease, gave positive and hopeful results. According to the results of testing an inactivated formulated vaccine obtained in the laboratory from oncospheric components, data are presented on the decrease in the number of diseased animals. There is a question about the sequencing of antigen with its subsequent use in the industrial production of vaccines at one of the biofactories under the Ministry of Agriculture of the Russian Federation.
