Abstract: The objective of research is to analyze the state of livestock breeding in the Omsk Region and to identify the best breeding farms. Objectives: to conduct a comparative assessment of milk productivity of cows in breeding farms. The following results were obtained: among the breeding farms of the Omsk Region of red breeds, the highest milk productivity indicators are: by milk yield in ZAO Bogodukhovskoye – 8195 kg (according to individual accounting), by mass fraction of fat (MF) – 4.16 % in SPK Bolshevik for red-colored Holsteins. The leader among the breeding farms of black-and-white color by milk yield is PR ZAO Kirova – 8214 kg, and by MF PR ZAO Rassvet – 4.22 %. The optimal reproduction indicators in breeding farms are based on the yield of calves, which allows the sale of breeding bulls and super-replacement heifers: for red breeds – 80–93 heads, and for black-and-white breeds – 88–91 heads. The productivity of the maternal ancestors of the Red Steppe bulls is: milk – 7,869 kg, MFA – 4.12 %; in the Angler breed: milk – 8,355 kg, MFA – 5.07 %; in the red-and-white Holstein: milk – 8,432 kg, MFA – 4.27 %. Among the red breeds, the highest productivity indicators are in the mothers of the red Danish bulls: milk yield – 11,716 kg, MFA – 4.25 %. In the black-and-white breed, the maximum milk yield is in the mothers of the S.T. Rokita line, and in the black-and-white Holstein – R. Sovering. More important is the assessment of the quality of the offspring. At the breeding enterprise, out of the total number of bulls-producers, 45 heads are assigned the breeding category "improvers" (of which 18 heads are black-and-white Holsteins, 2 heads are black-and-white, 25 heads are red breed).
