Abstract: 300 day-old broiler purchased, initially weighed and dvidied into A, B and C groups, 100 chicks eacdh and provided with white, blud and red lights, respectively. Floor brooding system was arranged. Initially broiler started and later finisher feeds (both iso-caloric and iso-nitrogeneus) and water were made available over 24 hours. Agonistic behaviour was recorded with 2 minutes interval over 24 hours during 2nd, 4th and 6th weeks by using time Sampling Technique. Total average feed intakes (3.394, 3.366 and 3.362) and live body weights (1.495, 1.510 and 1.491) kg per broiler were not different significantly for A, B and C groups, respectively and similarly followed by their interactions between groups and weeks (P>0.05). However, week response was significant for all (P<0.01). Broiler carcass recovery was 58.0, 60.0 and 59.0 percent for A, B and C groups. Mortality was higher for blud (B) than then red ? andwhite (A) light group (6, 4 and 2%), respectively. Both, average aggression instigator and target incidences were higher for A (3.31 vs 1.22) than C (1.92 vs 1.08) and B (0.78 vs 0.47) I ncidence/hr/groups, respectively. It is concluded that blue light provided calm and quietness due to least agonistic behaviour within broiler groups mates than red and white groups.
