Abstract:: A series of 8 experiments was conducted to investigate various methods of delaying the sexual maturity of developing White Leghorn (W. L.) pullets grown during a period of increasing day length and to control the feed intake of W. L. layers. In the first five experiments W. L. pullets were...
