Milk productivity of cows using an experimental mineral- probiotic supplement

Monitoring the probiotic, market has shown that some of them are not in demand due to the high cost. Therefore, new, more effective and cheaper drugs are being developed. On the basis of an experimental mineral-probiotic supplement, a scientific and economic experiment was carried out. Studies have found that over the period of the experiment, the milk productivity of the cows of the experimental groups increased in all groups compared with the control.
