Abstract1. Comparisons of age, food intake, body weight and body composition at the onset of sexual maturity were made between dwarf and normal chickens from lines selected for high or low juvenile body weight.2. At the same age birds which had started to lay were significantly heavier and contained significantly more abdominal and carcass fat than those which were not laying.3. Differences between normal and dwarf pullets within lines varied with genetic background, indicating differences between lines in meeting a body weight or a body composition requirement, or both, for the onset of sexual maturity. |
