Abstract: An experiment was carriedout to examine the effect of group size on production and behaviour of broiler. 600 day-old broiler were purchased and brooded for two weeks and later randomly divided into three groups i.e. A (150), B (200) and C (250) at the beginning of 3rd week of age and housed at Poultry Experiment Station, Department of Poultry Husbandry, Tando Jam upto the completion of 6 weeks. The groups of broiler were housed under similar conditions and offered pellet feeds (iso-caloric and iso-nitrogenous). The result show that feed intake of broiler was different significantly between groups A (3.294), B (3.246) and C (3.208) kg/b, respectively. Average live body weight of broiler were significantly increased with the progress of period i.e. W3 to W6 (P<0.01), but the weights were not significantly different i.e. 1.846, 1.876 and 1.880 kg/b in groups A, B and C, respectively. Social behaviour results show that the average agreesion instigated by broiler under A, B and C groups were 0.6, 0.6 and 1.2 incidences/24 hrs/b (P>0.05). Average aggression target of broiler under group A, B, and C were 0.5, 0.9 and 1.0 incidences/24 hrs/b (P<0.01). Average aggression avoidance, flying and playing behaviours of broiler groups were not different significantly (P>0.05). Feed conversion ratios in groups A, B and C was 2.022, 1.963 and 1.944 and net profit earned was Rs. 14.250, 16.068 and 16.548 per broiler for A, B and C groups, respectively.
