Technological properties of cow milk with the addition in their diet of silage prepared with bio-preservative “GreenGrass 3×3”

The completeness of the provision of the body of highly productive cows with the necessary set of nutrients depends on the set of feeds included in their diet, as well as on their quality. The purpose of the research is to study the effect of silage with the biological preservative “GreenGrass 3×3”...
