Abstract

The immunogenetic strucrure of Holstein cattle being imported from Germany and Hungary is determined. The presence of antigenes being met seldom - Z' (EAA-locus), P2, T2, Q, I?, J?2, K?, P?, Y?, B?? (EAB-locus), R1 (EAC- locus) and M (EAM-locus) is characteristic of the researched group of animals (1116 heads). Their summary frequency of being met made 17,64 %. The antigenes – A2 (EAA-locus), G2, G3, Y2, E?2, E?3, G?, Q? (EAB-locus), C1, C2, E, W, X2 (EAC-locus),.F (EAF-locus), H?  (EAS-locus) are met with high frequency.They have been discovered in 40,05- 98,39 % of animals. Analysis of distribution of the genotypes in EAF-locus. pointed to the breach of genetic balance, that is caused by oversurplus of homozygous genotypes V/V and shortage of heterozygous F/V. Analysis of distribution of EAB-alleles exposed the high frequency of being met of the allele G2Y2E?2Q? (q=0,2711), and also a presence in the researched group of animals the alleles typical for the black and white cattle, red steppe and other breeds of cattle. The level of homozygosity (Са) concerning  EAB-locus. made 10,9 %. The received materials. will be     used in future for the improvement of selection and breeding work with the imported Holstein cattle.
