Recommendations published by NRC during 2001 are resented in this paper. These recommendations present significant step forward compared with those from 1989, which were widely accepted in many countries and were used in many herds to reach the level of production not possible before. The new system brings changes in almost every aspect of cow feeding. The equations for the calculation of energy of the diet are changed and protein value is expressed in a new way. The dry matter intake calculated is based on new equations while more attention is paid to carbohydrates, minerals and vitamins. The use of in situ obtained values is enabled in order to adjust values for feeds used in various farms. However, before this system is used in our country, like in the case of 1989 recommendations, it will be necessary to build a database with all relevant parameters for domestic feeds used in the feeding of dairy cows.
