Growth and food intake of broilers under various lighting regimes.
1. Growth rates and daily food intakes of small, sexed groups of broilers were compared under different photoperiodic regimes during the period from 28 to 49 d of age. 2. Reduction in the duration of illumination did not impair growth rate. 3. The sexes showed a differential response to the treatments. 4. There was evidence that the enhanced performance of females was due to an improvement in food conversion efficiency.
