The paper characterizes 52 producers of red steppe, 49 - red Danish and 169 Angler bulls of “Barnaulskoye” enterprise in terms of erythrocyte antigen occurrence. The authors used 53 antiserums in order to determine erythrocytic antigens of 9 genetic systems. The highest frequency observed was F antigen frequency equal to 0.976-1.000. This gene was not observed in one servicing red steppe bull and four servicing Angler bulls. All red Danish bulls had F allele in a homo- or heterozygous state. The concentration of antigens A2, B2, O1, Y2, G’, Q’ (system B), C1, C2, E, R2, W, X2 (system C), H’ (system S) in the red bulls was high and equal to 0.249-0.592. The frequency of erythrocytic antigens B1, I1, P2, T1, T2, Y1, I’, D’, J2’, P1’, B” (B), R1 (C), J (J), S2, U and H” (S) was the lowest at 0-0.122. All 53 blood factors were observed in Angler cattle, but no antigens B1, P2, R1, U и B1, Y1, B” were observed in the red steppe and red Danish cattle. There are no significant differences observed in genetic similarity among three red breeds; the index of genetic similarity are 0.9211-0.9307, which indicates a high relationship among them. The highest number of ejaculates and native sperm was obtained from Angler servicing bulls, the excess over other breeds was 11.9-13.9 and 15.1-42.8%. Red steppe bulls were characterized by lowest amount of ejaculate and less bioproducts for cryopreservation were received from them. The total breeding efficiency of cows with red steppe bull sperm was 85.1%, the superiority over Danish and Angler red cattle was 7.1-11.5%.
