[Comparative studies of feed consumption, performance data and physiologic values among cows with high and low milk protein content].
One high protein group (HE) and one low protein group (NE) were formed from cows differing greatly in milk protein content out of 12 feeding trials. The differences between both groups were insignificant resp. not well defined in the parameters of the feed intake, energy conversion, development of live weight and the physiological parameters, so that suppose, cows with high or low milk protein content do not differ in the investigated parameters. As a possible characteristics feature the titer of free amino acids in blood serum is indicated.
