Inglés. Outlined are results of studying the regularities and special features of consuming feeds by high-productive cows in the Crimea's extreme conditions. To improve the level of using the genetic potential of highly-productive dairy cattle, it is believed to be expedient to use in the Crimean conditions the following annual feed structure, %: hay -13, haylage - 15, feed beets - 6, silage - 5, green feeds - 19 and concentrated - 42% (according to nutritive value thereof. Such measures allow increasing in dry matter consumption by 11.7-15.7% on the account of raising the hay and haylage part. At the stage of raising a lactation curve (milking) along with the provision of full-ration feeding of highly productive cows, increasing in the frequency of dipensing concentrated feeds is a significant technological measure. It contributes to improving the level of consuming the dry matters of the ration by the animals, their milk productivity and milk quality. Technological methods for feeding the highly productive cows approbated in the production are expedient as they contribute to achieving an annual economic effect within the boundaries from 29 to 180 UAH (5-36 USD) per cow.
