Abstract

The purpose of the research was to study the frequency of erythrocyte antigens of 9 genetic systems, the number of genotypes and the frequency of alleles in the F-V system in sires of four breeds at the OAO “Barnaulskoe” Bull stud, as well as to establish indices of genetic similarity between them. The characteristics of 138 sires of Black-and-White breed, 103 of Red-and-White, 106 of Simmental and 270 sires of red breeds have been given. 53 antiserums were used in the tests. The high occurrence of blood factors A₂ (system A), B₂, G₂, O₁, Y₂, G’, O’ and Q’ (system B), C₂, E, W, X₂ (system C), H’ (system S) and Z (system Z) in sures of all four breeds ranged from 0,204 (O’ in sires of Red-and-White breed) to 0,825 (X₂ in the same breed). The frequency of the F antigen in all breeds was maximal and varied from 0,874 in sires of Red-and-White breed to 0,981 in sires of red breeds. On the contrary, the occurrence of blood factors B₁, I₁, I₂, P₁, P₂, Q, T₁, T₂, I’, J₂’, K’, P₁’, Y’, B” and R₁ was significantly lower and amounted to 0–0,130 in sires of Black-and–White breed, 0–0,087 in sires of Red-and-White breed, 0–0,094 in Simmental sires and 0,004–0,137 in sires of Red breeds. Sires of red breeds had all 53 antigens, Black-and-White sires did not have 8, Red-and-White sires did not have 11, and Simmental sires did not have 9 blood factors. There were no significant differences in the value of the genetic similarity index between the animals of the four breeds. However, there was a tendency to increase the similarity between the sires of Black-and-White and Simmental breeds on the one hand and the sires Red-and-White breed on the other (r=0,8837 and 0,8765). The least close breeds are Red-and-White and Simmental on the one hand and Red breeds on the other (r=0,8613 and 0,8585). This is also indicated by the occurrence of genotypes and alleles in the F-V genetic system. Thus, significant differences in the number of all genotypes and frequencies of alleles were revealed between sires of Simmental and Red breeds.
