Abstract:

In black-and-white and Holstein breeds the blood serum for ALT and AST

ferments concentration alkaline phosphatase and amylases has been studied. Under

the results of a massive blood research as well as on the base of genetic-population

analysis with the glance of interior-complementary selection the animal groups of hypo-

fermentative, transitional and hyper-fermentative types were formed. They served as

the basis for interior constitution type classification development in dairy cattle.

Keywords:
