Abstract

In the conditions of a dairy commercial enterprise, a scientific and economic experiment was carried out on two groups of cows – analogues. The duration of the experiment was 104 days. In a scientific and economic experiment, we studied the effect of feeding a suspension of chlorella in the first phase of lactation in the diets of freshly calved lactating cows and cows 2–3 lactations per amount of milk fat and protein in milk. The analysis of average values according to the dynamics of changes in the content of milk fat was carried out. Data were obtained on the positive effect of chlorella suspension on the quality indicators of fat and protein in the milk of cows of the experimental group.
