The effectiveness of using the probiotic drug “Baikal EM 1” in their rations of cows

Abstract

Among feed additives, probiotics used in animal husbandry are of great interest, containing live microorganisms that belong to the normal, physiologically justifi ed microfl ora of the intestinal tract and have a positive eff ect on the animal’s body. Newly created drugs (eff ective microorganisms – EM-drugs) are a set of microorganisms that have a benefi cial eff ect, clean all living things from pathogenic microfl ora and harmful chemical compounds. The purpose of the work was to establish the optimal doses of feeding the probiotic drug “Baikal EM 1” in the rations of dry and lactating cows in connection with the eff ectiveness of milk production. The researches have been carried out on cows of Black-and-White breed in the NE “Ufi mskoe” of the Bashkir Scientifi c and Research Institute of Agriculture, where the feed base and the condition of the production facilities met the veterinary requirements. The optimal dose and methods of application of the drug “Baikal EM 1” of probiotic action in the rations of cows in the Republic of Bashkortostan have been determined and tested. The positive infl uence of the probiotic drug on the processes of rumen digestion, digestibility and assimilation of nutrients, physiological and biochemical status, milk productivity, reproductive functions, the quality of the off spring and its livability has been established. The eff ect of using the drug “Baikal EM 1” in diff erent dosages on hematological parameters, digestibility and assimilation of nutrients, and nitrogen metabolism has been studied. The economic justifi cation of the use of the probiotic drug “Baikal EM 1” in the rations of cows has been given. It has been found that the most eff ective from the zootechnical, biological and economic points of view is to use the probiotic drug “Baikal EM 1” in the dose of 50 ml/head/day.
