1. Mature domestic drakes of 7 genotypes, ranging in live weight from 1.1 to 5.1 kg, were each given a daily allowance of feed just below the level of recorded ad libitum intake. 2. House temperature was maintained at 26 degrees C for 16 weeks and then at 10 degrees C for a further 8 weeks. 3. Under these conditions, live weight quickly adjusted to the level of feed supplied and then remained stable. 4. Regression of metabolisable energy intake on live weight (W) yielded estimates of maintenance requirement of 583 kJ/kgW(0.75).d at 10 degrees C and 523 kJ/kgW(0.75).d at 26 degrees C.
