Abstract: The possibility of replacing the silage-concentrate type of feeding for dairy cows with silage-hay, using silage prepared with the probiotic preparation KTL 18/1, was investigated to optimize nitrogen metabolism in the rumen and blood, thereby obtaining high-quality milk suitable for the production of hard cheeses. Modern zootechnical, physiological-biochemical, and statistical research methods were used in the experiment. It was established that the use of experimental silage in the composition of silage-hay type contributes to the optimization of nitrogen metabolism in the rumen and blood, ensuring milk production is suitable for cheese production. The obtained results allow recommending farms in the Polissia zone (Ukraine) to use a silage-hay type of feeding for feeding cows of average productivity, which will make it possible to increase the yield of milk per 1 ha of agricultural land, reduce the cost of a feed unit of the ration and save concentrated feed (up to 15-20%).
