Abstract.

Modernization of cattle breeding industry in Russia is done by creation of

a large dairy farms wide network and active breeding of highly productive cattle. During

the formation of highly productive herds on dairy farms and complexes is necessary to

consider the imported cattle adaptation to the specific conditions of different regions.

The article deals with comparative evaluation on a range of economic useful signs of

Holstein heifers imported from Holland, Germany, the United States and bred in the

zone of the forest-steppe Volga region under conditions of intensive milk production

technology with loose-box contents. The exterior features, differences in productive,

reproductive properties and qualities of milk of the different breeding heifers have been

revealed. The results of the research testify to the high milk productivity of Holstein

heifers of all experimental groups, however, Animals of Dutch selection possess the best

milk productivity. To increase milk yield in dairy herds in the forest-steppe zone of the

Volga region it is necessary to use the genetic potential of Holstein breed. Preference in

the formation of highly productive herds should be given to animals of Dutch selection.
