Abstract
Relevance. This article shows the influence of the same doses of natural mineral supplements "Stimul" and smectite trepel, their positive impact on increasing productivity, as well as changes in the hematological parameters of the blood of lactating cows.
Results. Feeding natural zeolites provided the need for biologically active substances and improvement of individual indicators of dairy products.The mass fraction of fat in the 1st experimental group was 0.1% higher, and the amount of protein was in the range of 2.9–3.1%. At the same time, it should be noted that the most stimulating effect on mineral metabolism in the body of lactating cows with the same composition of rations was better used in the mineral part of the diet was better used, which included 3.0% smekty trepel from dry matter.
