Abstract

The article presents research data on the study of the effect of feeding alfalfa grass haulage with the addition of 3 g/t of the biological preservative "Kazbiosil" in comparison with haylage harvested without preservative on the dairy productivity of lactating cows. The experimental animals of the control group ware feda haulage without a prezervativy from alfalfa grass as part of the diet feed, while the animals of the experimental group were fed a haylage with the introduction of a biological starter. At the end of the scientific and economic experiment, the animals of the experimental group outperformed the lactating cows of the control variant in terms of the average daily milk yield of natural and 4% milk, respectively, by 20.7; 20.9 kg or 1.4; 1.8 kg (P<0.05).
