Abstract

Effects of polygenes on economically important traits is one of the central problems in selection of livestock. Today it is known only small number of structural genes  whose polymorphism  is directly related  with manifestation of valuable traits in animals. This study was focused on possibilitys of genetical revealing and evaluation of economically important traits at cattle (muscle hypertrophy, growth performance and compositional and technological properties of milk) with utilization such marker genes as myostatin (MSTN), leptin (LEP), βlactoglobulin (BLG) and kappa-kasein (CASK) genes. All these genes occur rare example of direct relation between polymorphism of structural genes and development of economically important traits. An investigation in present study was undertaken to clarify the polymorphism of these  genes at some local Ukrainian breeds, such as Ukrainian White Head cattle (UWH), Ukrainian Gray cattle (UG) and Polish red cattle (PR).
