Breed features concerning the content of separate components of milk are revealed. One of the important criteria for the quality of raw milk is the number of somatic cells in milk, given that they are a reliable indicator of cows’ disease of mastitis. Therefore, to monitor the compet-itiveness of dairy farming requires regular monitoring of milk quality. This applies primarily to animals of domestic breeds, due to the small number of studies. The solution to this issue has led to research on the livestock of the Ukrainian brown dairy breed, which is kept in the State Enterprise "Experimental Farm of the Institute of Agriculture of the Northeast of the National Academy of Agrarian Sciences of Ukraine." The content of milk components was determined in the laboratory of the Institute of Animal Husbandry of the National Academy of Agrarian Sciences of Ukraine on Bentley equipment. As a result of research, it was found that both primiparous and adult animals had a sufficient level of milk productivity with high quality milk. According to all indicators regulated by the breed standard, they met these requirements. The first-born were inferior to adult animals both in milk yield and in the content of milk com-ponents. There is a significant correlation between individual indicators. The connection of different direction and level of reliability between separate qualitative indicators of milk is revealed. A positive relationship has been established between the content of fat and protein in milk, fat and dry matter, protein and casein, protein and dry skim milk residue. it has also been found that in adult ani-mals the bond strength increases. A significant negative correlation was found between the number of somatic cells in milk and the content of dry nonfat milk residue and lactose. Further improvement of the Ukrainian brown dairy breed should be aimed at improv-ing the quality of milk.</p&gt;}, number={4 (47)}, journal={Bulletin of Sumy National Agrarian University.
