Introduction. Dairy cattle breeding occupies a leading position among the livestock breeding sectors of Belarus, in which more than half of the fixed assets are concentrated, more than 50% of labor resources are occupied and more than 30% of feed resources are consumed, which creates conditions for its accelerated development along the intensifica-tion path. The purpose of the article is to determine the main factors and directions of increasing the efficiency of dairy cattle breeding in agricultural organizations in Belarus. Results. The redistribution of costs between supporting and productive feed in the direction of increasing the lat-ter as the most effective form of saving in animal husbandry is considered. It is proved that the further development of dairy cattle breeding should be carried out by improving breeding and tribal work to create a competitive Belarusian dairy cow. It is proved that the problem of the competitiveness of dairy products is the labor input, the main reasons for which are highlighted. An economic grouping was constructed according to the annual reporting data for 2017 for 190 agricultural organizations of the Brest region with developed dairy cattle breeding, where the profitability of milk sales was chosen as a grouping attribute. Conclusions. The analysis of the results showed that a high profitability of milk sales is achieved due to the greater density of the population, a higher average annual milk yield. The increase in the profitability of milk sales is accompanied by a decrease in feed consumption while increasing the consumption of concentrated feed per 1 centner of milk. To increase the profitability of the sold products and the productivity of cattle in the dairy sector, it is necessary to provide the animals with full and high-quality feeds of their own production, and to significantly increase the propor-tion of concentrated feeds in the diet. Efficient management of the dairy industry is only possible using intensive cattle production technology. Ways of increasing the efficiency of dairy cattle breeding are proposed. Key words: efficiency, optimization, balance, resource saving, genetic potential, newest technologies.

According to the current “Instruction” used in dairy cattle selection and breeding in the Republic of Kazakhstan, bulls-producers of dairy breeds are assessed according to the their offspring quality based on the principle of “peer daughter”. This means that the phenotypic indicators of the daughters of the tested bulls are compared with the corresponding indicators of their peers. In European countries with developed dairy cattle breeding, as well as in Canada, the USA, etc., to ensure a reliable forecast of the genetic value of individuals (primarily, bulls-producers), use is made of the best linear unbiased forecast method (BLUP method). This method implies that the breeding value of producers is determined by the deviation values of the development of traits of the examined animal from its average values in the population. Especially urgent area is the research aimed at improving breeding programs, including assessing the breeding value of bulls-producers of dairy breeds using BLUP methods based on the productive qualities of the mass of dairy cattle in the Republic of Kazakhstan. The research material included the data on the phenotypic indicators of the milk productivity of first-calf cows (the amount of milk yield, the content of fat and protein in milk, the yield of milk fat and protein) of the Holstein black-motley dairy cattle breed, obtained from the information and analytical database of the Republic of Kazakhstan for 2016–2017. It was found that when evaluating according to the official “Instruction”, 16 sires out of 256 bulls (6.2%) got the stud category in 2016, 14 sires (9.2%) out of 152 bulls in 2017, and – 30 sires of 249 bulls (12.0%) over the cumulative period. The results of the conducted research prove that the use of the classic “Instructions” in dairy cattle breeding has lower efficiency (by 42.8–90.0%) as compared with the assessment of the breeding value of bulls based on the BLUP method.The selection of sire bulls into breeding groups based on the “peer daughter” methodology is not reliable enough and rather ineffective. Comparing the results of assessing the breeding qualities of sire bulls, obtianed using two methods in all compared periods (2016, 2017, 2016–2017), the authors established a clear superiority of the BLUP method over the current Instruction used in the Republic of Kazakhstan.
