The introduction of modern technological advances and principles of dairy herd management, which were developed in the member countries of the International Committee for Animal Registration (ICAR), contributed to the increase in milk productivity of pedigree cattle at the national level. The harmonization of national regulatory documents with the methodological principles developed in ICAR is a promising area. The study of new methodological approaches to the assessment of milk productivity shows that one of the differences in the assessment of daily milk yield, milk fat and protein yield is the different frequency of performing the corresponding work on the control milking of cows, the formation of a daily milk sample and the necessary mathematical calculations. In the in article various approaches to assessing the daily yield of the main dairy components during 2- and 3-fold milking of cows of a herd of pedigree black-and-white cattle are considered and coefficients are proposed for recalculating the daily content of fat and protein in milk. At the same time, the presented research results, in general, coincide with the main trends in the dynamics of milk fat and protein indicators shown in the ICAR recommendations.
