The research was carried out at the Chutyrsky agricultural production complex in the Igrinsky district of the Udmurt Republic. We considered the milk productivity and quality indicators of milk from Holstein cows. According to the presented results, it was revealed that in the conditions of the Chutyrsky agricultural production complex in the Igrinsky district, the share of cows with a milk yield of 9001–10000 kg of milk is 35.0 %, among first-calf cows it is 22.9 % of the total number of cows tested. In general, the level of milk productivity of the studied herd is assessed as quite high. The mass fraction of fat in the milk of cows varies in the range of 3.20 % – 4.79 %, the mass fraction of protein in the milk of cows varies in the range from 2.7–3.29 % among all tested livestock. The fat and protein content in milk were below the breed standard in 14.7 % and 25.3 % of cows, respectively.
