The article characterizes 201 servicing bulls of Red Steppe Breed, Angler Breed and Red Danish at the breeding farm “Barnaulskoe” and 249 cows of Red Steppe Breed at 5 breeding farms of the Altai Territory according to the frequency of erythrocyte antigens. The researchers tested 51 antiserums and defined erythrocyte antigens of 9 genetic systems. They frequently observed B2, Y2, C2, X2 and H antigens of servicing bulls (0.403-0.632) and cows (0.394-0.506) and rarely observed A1, K, R1 and U antigens of Red Breed bulls (0.005-0.015) and cows of Red Steppe Breed - 0.004-0.012. The authors highlighted variations on the frequency of concrete antigens among the breeding bulls of 5 lines. The highest variation among the lines on the frequency of А2 antigen was observed as 0.500, В2 - 0.395, Q - 0.395, С2 - 0.667, Е - 0.641, R2 - 0.346, W - 0.579, X2 - 0.355, С - 0.389, L - 0.416, М - 0.423 and S1 - 0.417. The bulls of various lines lack of 9.8-35 % of erythrocyte antigens of the total antigens. The least genetic similarity was observed among the bulls of Korbitsa 16496 line and other 4 lines (r = 0.803-0.816), the index of genetic similarity was 0.853-0.891 among the other lines. The cows of Red Steppe Breed of various lines have their own peculiarities on the frequency of erythrocyte antigens. The variation among the lines of В2, О2, Y2, С2, Е, W and C antigens was 0.133-0.335. The highest variations among the cows of different lines are observed at О1 (0.077-0.615), D (0-0,462) and H (0-0.524) antigens. The indexes of genetic similarity among the lines were 0.836-0.879. The highest similarity was found between Korbitsa 16496 and Gannibala 4776; the lowest - between the 1st line and Hoyvig 13618677. The indexes of genetic similarity demonstrate the significant variation between the lines of Red Steppe Breeds in the Altai Territory.
