Bolhova N. Plant-breeding-genetic estimation of intermediate genotypes by the Ukrainian borax of suckling breed which is created

The object of researches is Animals of Ukrainian brown milk, that is created to the cross-breed. A research purpose is Establishment of efficiency of the use of genetic potential of shvits breed of a different selection for the improvement of productive and technological qualities of animals of lebedinskiy cattle. The methods of researches are zootechnicss, biochemical, physiology, morphological, technological, mathematical statistics, economic. Results of researches: 1. For a theory - new given relatively influences of stake of heredity of shvits breed making better on the indexes of growth, productivity, reproductive power are Got, intermediate genotypes at creation of the Ukrainian brown milk breed. The methods of estimation of qualities of the families 2 are considered. For practice - the Ukrainian brown milk breed, that is created has the high indexes of milk productivity, reproductive and adaptation power, therefore it grounds to do a conclusion about possibilities of its effective use on conditions of the valuable feeding in the economies of Forest-steppe of Ukraine. Sphere of the use - dairyings of Ukraine.
