Abstract:
The study was conducted on 160 chabro broiler chicks, which were distributed in four different light treatment groups, i.e., Tw; white (650nm), Tg; green (565nm) and Tb; blue (430nm) light emitting diodes (LED) bulbs (3 Watt each) and incandescent light bulbs (60 Watt each) as control (Tc). At the day time open-sided house were open from 10.00 AM to 4.00 PM and the rest of the time sides of the house were covered with black colored tarpaulin sheet. Pens were light proof to avoid light interference during dark hours. The performance of broiler chickens was evaluated based on carcass characteristics. The result revealed a non-significant effect on carcass traits (dressing percentage and eviscerated weight). It could be concluded that the use of light emitting diodes (LED) light is better than incandescent light in terms of energy utilization efficiency and working life span without affecting the broiler carcass traits.
