The present study was conducted to assess the behaviour of broiler birds in an open-sided house under supplemental lighting programme using light emitting diodes (LEDs) and incandescent light. To perform this study a total of 240 straight run commercial Vencobb broiler chicks were procured, distributed in four different light treatment groups i.e. Tw; white (650nm), Tg; green (565nm) and Tb; blue (430nm) light LED (3 Watt each) and incandescent light bulbs (60 Watt each) as control (Tc) in 12 pens (4x3 factorial design) and reared from day old to 6th week of age. The coloured curtains were placed according to the treatment groups requirement inside each pen of shed and each pen was completely enclosed to make it light proof. Light intensity was measured with the help of light intensity meter (Lutron®PLX-111 light meter with range 0-20000 LUX). Frequency and percent duration of feeding, drinking and dozing behaviour differ significantly among different treatment groups in different weeks of study whereas, other behavioural parameters like resting, preening, wing flapping, head and litter stretching, pecking, avoiding, pushing, dust bathing, leg stretching, neck stretching and threats didn’t differ significantly among different treatment groups in different weeks of study. From the study, it can be concluded that birds under LED light treatment are having significant (p≤ 0.05) higher frequency and duration of feeding thus LED light bulbs could be a better alternative light source than incandescent light bulbs for commercial poultry facilities to reduce energy consumption and better economic gain without affecting the performance and welfare of broiler chickens.
