The aim of the research is a comparative assessment of the morphological and functional properties of the udder and the productivity of heifers zoned in the region of the red steppe breed and red-mottled cattle with loose content and year-round feeding of the same type, imported into the new breeding conditions. The object of research - heifers red steppe and red-mottled breeds of cattle. Monitoring of heifers of the red steppe breed revealed that among the experimental livestock (n=25) 17 individuals or 68% belong to animals with a Cup-shaped udder, 4 heads or 16% - with a bath-like and rounded forms. Commission assessment of the peers of red-motley breed of animals not identified with a rounded shape of the udder. These are mostly accounted for heifers with a bowl-shaped form of the udder - 76% vs 24% with vandoorne form. The rate of milk yield was higher in the group of red-mottled cattle - 1,73 kg/min with differences with red steppe peers equal to 0,2 kg/min (P>0,999)...
