Abstract
The data on feed quality and their actual nutritional value in the conditions of the North of the European part of Russia are presented. The averaged data on the nutritional value and chemical composition of feed received for analysis from agricultural enterprises of the Vologda oblast are presented. There is a tendency to decrease certain indicators characterizing the nutritional value of feed, such as crude protein, crude fat, crude fiber, as well as the content of chemical elements calcium and phosphorus. The data on the actual nutritional value and chemical composition of feed that have developed in the Vologda Oblast indicate the need to improve the regional feed production system that meets the requirements of standardized feeding of highly productive dairy cows.
