THE STATE OF LIVESTOCK BREEDING IN THE OMSK REGION

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).
