[PHYSIOLOGICAL RELATIONSHIP OF ERYTHROCYNE ANTIGENS WITH INDICATORS OF HORSE SPERMOGRAM].

Abstract

The possible presence of the physiological relationship of erythrocyte antigens of the A, C, D, K alleles of the blood group systems in the examined horses of the Ukrainian selection with the spermogram major parameters has been demonstrated. It has been found that when investigating ad/bcm and dg/cgm alleles of the blood group system D in the stallions, there was the physiological tendency of the decrease in the semen activity on average less than 5 points; at the presence of ad/cgm, ad/d, ad/ de, ad/dk, bcm/d, bcm/de, bcm/dg bcm/dk cegm/cgm, cegm/d, cegm/dg, cegm/dk cgm/ceg, cgm/cgm, cgm/dg, cgm/dk de/ cgm, de/dk dg/di, dk/d, dk/de, dk/dk alleles the spermogram of the average quality with the activity of the semen on average from 5 to 7 points was obtained; at the presence of bcm/cgm, dg/dk, de/d, egm/d, cgm/de alleles high parameters of semen activity, more than 7 points, were received. The tendency of the increase in the semen concentration was revealed in the examined stallions having a/- allele of the blood group C. The possible decrease in the semen concentration in the stallions having a/-allele of the blood group K was shown. The alleles of the blood group system D had the highest statistical impact on the volume of the ejaculate, the activity, concentration and the number of pathological forms of semen, the correlation coefficient was 0,36; 0,31; 0, 43 and 0,27, respectively. At the same time it has been found out that the alleles of the blood group systems A,C and K had the coefficient of correlation with the examined parameters of the semen at the level of not more than 0,07.
