Influence of feed mineral supplements on morphological and biochemical blood indicators of lactating cows

The article presents data on morphological and biochemical blood parameters, the content of total protein and its fractions in the blood serum of lactating cows when using new mineral supplements at a dose of 100 g and 350 g per head per day. In experimental group 2, an increase in the hemoglobin index was 11.88% (P≤0.05), in inorganic phosphorus - 27.00% (P≤0.01), in globulins - 4.81% (P ≤ 0.05) compared to the control group.
