In early studies of the breast absorbed 0,38 ± 0,016 mmol/l of volatile fatty acids, which becomes 47.50% usage. At the third stage of lactation milk yield of cows in this group average becomes 592 ± 15,2 kg of natural and 573 ± 16,1 kg milk with 4% fat. We found that daily use of dynamics VFA mammary gland characterized by a gradual increase in their absorption of 1.33 times in the first, 1.53 times in the second-and 0,42 ± 0,016 to 0,56 ± 0,017 mmol/l to 0.48 ± 0,018 mmol/l, and an average adsorbed - 0,51 ± 0,017 mmol/l (43.48%). Nutrient levels at the end of the fifth month of lactation was 343 ± 17,4 kg. In the following months lactation cows live weight increased to 413 ± 16,4 kg, which becomes 119.7% by weight of the animals at the end of the first month of lactation.
