CONSOLIDATION OF UKRAINIAN BLACK SPOTTED DAIRY BREEDS ANIMALS WITH DIFFERENT GENOTYPES BY ESSENTIAL HOUSEHOLD USEFUL SIGNS
Level of phenotype consolidation of the essential household useful signs in animals of Ukrainian black spotted dairy breed with different part of Holstein’s heredity was held. Concluded, that practical utilization of phenotype consolidation coefficients in a way of objective estimation criteria will let in perspective control and differentiate in a proper manner consolidation processes of different animal selection group by separate signs, including the animals of Ukrainian black spotted dairy breed. By the level of phenotype consolidation for live weight, measures and indices of body construction, milk productivity, life productivity and duration of household animals’ utility with different types of genotype were different with each other. In majority cases the most consolidated by noticed signs were cows with Holstein’s part of heredity 50 %, and the lowest consolidated - with Holstein’s part of heredity 100 %.
