This study was conducted at breeding farms in the Udmurt Republic, Russia, Agricultural production cooperative "Kolos", Agricultural production cooperative (Kolkhoz) "Udmurtia", Agricultural production cooperative named after Michurin of the Vavozhsky district. Heifers of the Russian black pied breed born in 2013 and 2014 were used
Probiotics have been used in various branches of animal husbandry for a long time, effectively replacing feed antibiotics. Specialists actively use the property of probiotics to show antagonism to pathogenic strains that have gained resistance to antibiotics. Their eff ectiveness is manifested in the possibility of obtaining environmentally safe products, has a metabolic and antiinfl ammatory eff ect, as well as stimulating local immunological protection. The purpose of the research was to identify the eff ect of probiotic drugs on economically useful and biological indicators of bee colonies under the conditions of the Udmurt Republic. In order to increase the natural immunity of bees and their productive indicators, probiotic drugs developed by LLC “NVP “BashInkom” such as ApiVrach, SpasiPchel, produced on the basis of bacteria of the genus Bacillus Subtilis, and PcheloNormoSil containing Lactobacillus, Enterococcus and yeast-saccharomycetes were used as stimulating additives.Studies have been conducted to determine the stimulating eff ect of the studied drugs, the positive dynamics of the growth of the number of worker bees, the increase in the strength of bee colonies to the main honey collection have been revealed, which indicates the eff ectiveness of the use of stimulating feed additives based on probiotic bacteria. As a result of their use the production volumes of gross and marketable honey, wax productivity increased, increased resistance of individuals to diseases was revealed. It was found that the use of probiotic drugs had the positive eff ect on economically useful and biological indicators of bee colonies under the conditions of the Udmurt Republic. The use of the probiotic drug ApiVrach in combination with PcheloNormoSil showed maximum eff ectiveness.
