The GDR report contains 34 pages, 14 tables, 9 references to literary sources, presented in 3 sections. The work was carried out during 2018. Objects of research - exterior type of cows, genealogical structure of herds, selective genetic parameters of the main characteristics of productivity, patterns of dynamics of milk production of cows. Method of research - used genealogical, population, genetic-mathematical, estimation of genotype of animals, biometric and statistical analysis of selection information, conclusions. The purpose of work and research tasks is to form a breeding information base for quantitative and qualitative indicators of cow productivity, to evaluate the type of structure of a body of dairy cattle in a linear way and to substantiate the optimal selection scheme for dairy cattle populations. To achieve the goal set the following tasks: 1.) to form an information database on quantitative and qualitative indicators of dairy productivity, reproductive ability, assessment of body structure and quality of cow's lips; 2) to evaluate the active part of the population of dairy cattle on the quantitative and qualitative indicators of dairy productivity, reproductive ability, exterior type; to evaluate the role of bull-leaders in genetic improvement of breed; 3) to study the effectiveness of the existing system of evaluation, selection of the breeders and theoretically substantiate and recommend breeding methods for the improvement of dairy breeds. During the research the electronic database of quantitative and qualitative characteristics of milk productivity, reproductive ability (Ukrainian red-and-white milk breed - 530 goals, Ukrainian black-and-white milk breed - 300 heads, Holstein (black-and-white suit) - 240 goals), linear Assessment of body structure (298 goals) in Excel format. In the herds of Holstein, Ukrainian red-and-black-breasted dairy breeds are breeding animals belonging to 12 lines. The analysis of the data of the productivity of individual lines gives grounds to assert that the animal lines can be attributed to more productive and perspective breeding: Bell 166736674 (n = 121 - 6947 ± 113,1 kg, 3,74 ± 0,021% fat, 3,31 ± 0,019% protein) Valiant 1650414.73 (n = 138 - 8217 ± 108.7 kg, 3.68 ± 0.024% fat, 3.30 ± 0.022% protein), 267150.60 (n = 108 - 7308 ± 96.2 kg, 3.80 ± 0.018% fat, 3.26 ± 0.031% protein). Prospective in this respect, there are fruit growers: in the conditions of the breeding plant "Zolotoniske" - Benjamin 7866444 (31 goals - 6947 ± 113,1 kg, 3,74 ± 0,021% fat, 3,31 ± 0,019% protein), Belisar 35897 (19 goals - 6674 ± 87,3 kg, 4,11 ± 0,018% fat, 3,12 ± 0,032% protein), Sarazin 1401467726 (82 heads of Holstein breed 8217 ± 115,1 kg, 3,20 ± 0,021% fat, 2,98 ± 0,041 % protein); in conditions of breeding reproducer "Progress" - Trenk 3036527156 (41 goals - 6285 ± 103,1 kg, 3,94 ± 0,031% fat, 3,41 ± 0,029% protein), Fidibus 579888341 (25 goals - 6287 ± 112,0 kg, 3 , 85 ± 0.031% fat, 3.38 ± 0.029% protein); in the conditions of the breeding loci "Lyashevka" - Manix 7355175 (28 goals - 6251 ± 108,7 kg, 3,82 ± 0,031% fat, 3,30 ± 0,019% protein); Spectrazone 105177655 (35 goals - 6817 ± 103.5 kg, 3.78 ± 0.026% fat, 3.20 ± 0.022% protein); Sparkles 105093441 (20 goals - 6723 ± 56.0 kg, 3.96 ± 0.013% fat, 3.35 ± 0.016% protein); Benjamin 7866444 (31 goals - 6702 ± 111.7 kg, 3.82 ± 0.012% fat, 3.29 ± 0.036% protein); Samba 7789514 (90 goals - 6861 ± 114.4 kg, 3.66 ± 0.031% fat, 3.27 ± 0.014% protein); Wilson 400720 (30 goals - 7308 ± 126.7 kg, 3.79 ± 0.017% fat, 3.42 ± 0.026% protein). The experimental results obtained are used in the development of programs and perspective plans for breeding with herds of Ukrainian black-and-white and red-bream dairy breeds in 3 farms in Cherkasy region. According to research results, an article was published in the Agrarian Bulletin, methodological recommendations were prepared.
