Directions of perfecting gene pool of equines of Ukrainian riding breed

Abstract

The purpose. To determine directions of formation of selection attributes on the basis of analysis of modern state of equines of Ukrainian riding breed and ways of its further perfecting. Methods. Zootechnical, genealogical. Biometrical analysis of data was carried out with the help of statistical methods and program VIOM. Results. The methodology of building of equines of Ukrainian riding breed is analyzed, volumes of selection operation with the breed with the purpose of development of its gene pool in a direction of heightening sports work capacity and with simultaneous saving of original parentage, type, and exterior are studied. The previous period of implementation of programs of selection is analyzed and ways of its further perfection in view of demands of the inner and outer markets are specified. Conclusions. As the basic method of perfecting Ukrainian riding breed they specified pure breeding with the purpose of martemperingselection attributes. It is expedient to use moderately breed crossing with the best representatives of output and other sports breeds of world gene pool at the level of blood adding. For saving genetic diversity in breed in the proximal years they will allocate not less than 5 continuers of each line and 2 new genealogical lines will be approved: Raufbold and Eola. The positive trend of evolution of parent families is prolonged and amount of nested mares in parent content is increased.
