title: [Growth studies of Holstein-Friesian bulls under different conditions of feeding intensity. 5. Derivation of energy requirement values].
abstract: From two long-term individual feeding experiments with groups of differentiated feeding intensity, energy requirement values were derived which take into consideration live weight development and which are in accordance with the measurements of nutrient and energy retention. The suggested energy requirement values show big differences between the intensity levels. It follows from this that energy expenditure from a low to a high feeding intensity first decreases and then, at a very high performance, increases again.
