[The interrelation of the interior indices of sires with the level of the heterozygosity for the polymorphic blood protein and enzyme systems].

Genetic polymorphisms of hemoglobin, transferrin, amylase, alkaline phosphatase, and ceruloplasmin, interior blood indices, and the reproductive function of servicing bulls were studied. Correlations between the heterozygosity level with respect to blood protein systems and enzymes and interior blood indices and the reproductive function of servicing bulls were detected.
