The aim of the research was a comparative analysis of the productive qualities of cows under the conditions of LLC "EPF Solyanskoe" of the Krasnoyarsk Territory. To conduct the research, a database was formed using the Selex program, which processing resulted in 276 cows selection at the age of third lactation and older and distributed first into two, further into four groups depending on breed (Black-Mottley, Red-Mottley) and linear affiliation (Vis Bek Ideal, Reflection Sovering). As a result, it was found that under the conditions of this agricultural enterprise, cows of the black-mottled breed of the Reflection Sovering line and cows of the red-mottled breed of the Vis Bek Ideal line were characterized by higher milk yields, as well as better reproductive ability compared to animals of another line of the same breed.
