THE IMPACT OF THE NEW FODDER ADDITIVE “M-FEED” ON THE MICROORGANISMS OF THE RUMEN CONTENTS OF CALVES AND THEIR GROWTH ENERGYDjunaidi Shŕramazanovich Gayirbegov, Vladimir Victorovich Mungin, Nadezda Ivanovna Gibalkina, Lyudmila Nicolaevna Loginova and Andrey Vladimirovich ValoshinAbstract This paper presents data on the influence of feed additives of the new generation “M-Feed” on the concentration of microorganisms in the contents of the gastrointestinal tract, the growth and development of calves of red-motley breed before 6 months of age. It was found that comparing three dosages of the preparation the most favorable conditions for reproduction, growth and survival of lactic acid bacteria, of yeasts and ciliates has a daily dose of the feed additive in an amount of 4 mg/kg body weight. This in turn has beneficial effects on the use of the feed ration, which ultimately increases the absolute gain in live weight on average by 15.2% and increased average daily gain by 15%. Using “M-Feed” in the optimal (4 mg/kg of live weight) quantity also contributes to a more harmonious body type of the calves, which are superior to their counterparts from the control group on the major altitudinal and latitudinal measurements. Conducted studies have also noted some improvements in body indexes of animals in the experimental group. In relation to the control group the index of stretching in animals of the first experimental group the was higher by 0.64%, from the second experimental group - by 0.31%, from the third – by 0.02%.
