For fattening steers, it is necessary to continuously increase feed intake and ensure a high energy concentration. Sufficient protein, while maintaining the right energy to protein ratio, ensures high daily weight gains. In the middle of the fattening period, the energy to protein ratio should be adjusted according to the growth potential of the animals. As the dry matter intake capacity increases, the amount of feed can be increased and the energy concentration can be reduced accordingly. During the final fattening phase, there is an increased risk of fattening steers becoming fat. Therefore, rations with a lower energy concentration and a higher protein concentration should be fed.
