Abstract. We investigated the increase in milk production of lactating cows with the introduction of Monosporin probiotic drug into the diet. The experiment was carried out in 2016 on 20 Black-and-White dairy cows in the Kemerovo region. Animals were divided into 2 groups of 10 animals each according to the principle of group-analogues. The selection took into account cows’ age, level of productivity, live weight, fatness, physiological state. The cows were kept in a tie-up way in a separate yard. The control group received the basic ration including haylage, hay, and mixed fodder. Animals from the experimental group received the same ration, and additionally Monosporin probiotic in the amount of 70 g per head 1 time per day with concentrated feed in the morning during milking. The daily ration of dairy cows contained 166.0 MJ of exchange energy, 17.5 kg of dry matter, 2,170 g of crude protein. The duration of the experiment was 60 days. The inclusion of the probiotic preparation in the diet of cows reliably increased milk yield per head for the reference period by 60 kg, or by 5.4% (up to 1158 kg), average daily milk yield – by 1.0 kg (up to 19.3 kg). The additive had no significant effect on the fat and protein content in the milk. A tendency to an increase in the mass fraction of fat by 0.02% (to 3.79%) was noted. The absolute amount of milk fat in the milk of cows in the experimental group increased by 6.0% (to 43.88 kg), compared with the control. In the experimental group, the additional profit for 60 days amounted to 525.9 rubles per head.
