abstract
The present experiment was conducted on 36 day old broiler up to four weeks of age to investigate “Body weight and gain in weight of caged broilers as influenced by different lighting sources” 36 day old Broiler chicks were randomly divided in to four groups with three sub groups of 3 chicks in each. Control (first) group received 100 watt incandescent bulb. Chicks in, second, third and fourth received 10 watt LED 60 watt incandescent bulb, 15 watt CFL 60 watt incandescent bulb and 5 watt CFL 100 watt incandescent bulb, respectively. Present result revealed that there was non-significant effect of different lighting sources on mean body weight and mean average gain in weight on performance of broilers was observed.
