Academician of the Russian Academy of Sciences, Member of Presidium of the Russian Academy of Sciences, Vice-Chairman of the Siberian Branch of the Russian Academy of Sciences, Doctor of Science in Veterinary Medicine, Professor, Honored Scientist of the Russian Federation, Honorary Worker of Higher Professional Education of the Russian Federation A. S. Donchenko's scientific research is devoted to the creation of highly effective science-based resource-saving technologies in animal husbandry and veterinary medicine, veterinary diagnostics, chemical preparations and veterinary devices. On the basis of biotechnological methods, he developed effective test systems for diagnostics of tuberculosis, leukosis, classical swine fever, infectious rhinotracheitis, viral diarrhea of cattle and diseases of red deer. Also, a highly effective anti-tuberculosis drug "nia-zon" was proposed for veterinary practice, with the help of which over the last three years 60 unfavorable areas have been recovered from tuberculosis with an economic effect of about 130 million rubles.
Together with the scientists of the The State Research Center of Virology and Biotechnology VECTOR (SRC VB VECTOR), methods of increasing natural resistance of the animal organism with the help of immunomodulators (polyribonate, ridostin) have been developed. These preparations are also used as adjuvants to increase the protective properties of weakly immunogenic vaccines against tuberculosis, horse strangles. All of them are widely implemented in veterinary practice. The developments are protected by ten certificates of authorship and patents of the Russian Federation.
The results of A. S. Donchenko's research have been published in 750 scientific papers, including 51 monographs, reference books, manuals, textbooks, scientific and methodological recommendations. His scientific works are protected by 22 patents and author's certificates. He is the co-author of the Altai-Sayan breed of red deer. Under his guidance 23 doctoral and 32 candidate dissertations were prepared and defended. A. S. Donchenko's students are successfully working in Yakutia, Novosibirsk, Omsk, Chelyabinsk, Amur regions, Primorsky and Altai territories, Altai Republic, Tajikistan, Kazakhstan and Canada.
