Summary Carcass composition, plasma protein, and hematocrit determinations were carried out on normal adult male chickens, and on adult males depleted by starvation for 4 weeks. For the first 2 weeks of depletion, N excretion was also determined for the starved animals. The following observations were recorded: 1. During 2 weeks of starvation the adult rooster lost approximately 25% of his body weight, and between 10 and 20% of his carcass N. 2. There was no loss in either weight or N content of feathers upon depletion; there was, however, a significant loss in feather fat. 3. The survival time of starved birds appeared to be related to their initial, prestarvation fat reserves. 4. The energy needs for repletion of depleted roosters, expressed on a body weight basis, were considerably higher than those necessary for maintaining normal animals. This appeared to be primarily a reflection of the greater proportion of ‘lean body mass’ (carcass N) in the starved birds.
