It was found that only 13.2 percent of milk samples provided the energy-protein balance of feed rations. The protein content in milk more rarely pointed to the lack of energy in feed rations (21.1 percent) than its excess (40.2 percent). Milk samples from 1st farm of the highest annual milk productivity more frequently than from the rest pointed out to energy-protein balance of feed rations. About 70 percent of milk samples from 2nd farm pointed to the lack of protein in the feed rations, and 36.9 percent to lack of energy. In summer there was much often an excess of protein in feedstuffs (48.6 percent), while in winter feeding an excess of energy (49.0 percent) was much more often observed
