In field conditions, a fasting period of 24 to 72 h after hatch is common, which is associated with delayed gastrointestinal development and yolk utilization and retarded subsequent performance. Hardly any information is available about the influence of diet composition in the first days on later life and additionally, effects of early feeding on thermoregulatory developmentare also not known. The aim of this study was to investigate effects of diet composition in early fed broiler chickens on their (thermoregulatory) development.
