Acceleration of the selection process in the population of Black and Spotted cattle by using genetic markers

Genetic researches of cattle breeds in the western region Ukraine are ecologically necessary, and they also become most actual connection with formation breed associations. In addition, research genetic characteristics various for use agricultural production is an attempt to identify common genetically determined herd. The choice such economically valuable by modern methods agriculture selecting herds a gene pool which this characteristic typical. structure was evaluated polymorphism blood groups genetic-biochemical systems. Experiments were carried out on erythrocytes plasma. Blood from animals taken jugular vein test tube heparin. Polymorphism proteins enzymes using method electrophoretic separation 13 % starch gel horizontal chambers followed subsequent histochemical staining. Group erythrocyte antigens according generally accepted methodology based hemolytic tests 48 reagents 9 characterized following features: transferrin locus greatest heterozygosity – 0.729, but Hardy-Weinberg law, balanced state (Р 0.104). dominant frequency occurrence allele Tf A 0.438, mainly as result AD1 AD2 heterozygotes. amylase (AM-l) unbalanced there not enough heterozygotes too many homozygotes 0.013). frequencies two alleles Am-l B C same amount 0.500. Hemoglobin monomorphic all investigated (hemoglobin AA). For purine nucleoside phosphorylase (NP), no significant differences within studied group animals.The higher Np L 0.872, H occurs less often, its 0.128, 0.225. As groups, vast majority detected help specific antisera found antigenic spectrum Black Spotted dairy breed. However, some (less than 0.057) extremely low (I1, Q, T1, T2, P1, P2, Y, R, U, I', B'', H''), others (J, ', U') slightly (0.082-0.099), (A2, G2, G3, B2, I2, O1, O2, Y2, D', G', E'2, O', Q', G'', C1, C2, E, W, X2, L, F, S, H'', Z) sufficiently high (from 0.11 0.888). has unique loci.
