| Abstract: | 1. A diet containing 110 g crude protein/kg caused smaller losses in egg weight, numbers and body weight in Babcock B300 layers than diets containing 90 g protein/kg, 6.56 MJ ME/kg or 7.90 MJ/kg. 2. The sequence of repletion of depleted birds was body weight, egg weight and egg number. For the first alone more than 420 kJ/d was required, for body weight and egg weight more than 630 kJ/d and for all three more than 1170 kJ/d. |
