Description An experiment was conducted to determine the influence of increasing broiler’s slaughter weight on, carcass characteristics, meat quality, sensory evaluation, immunity, and welfare. Commercial strain “Vencobb-430” chicks (n=280) were randomly distributed among eight groups consisting of 35 chicks in each. The experimental birds were fed on commercial maize soya-based basal diet. The broiler chicks were reared for up to 48 days and slaughtered at a different live body weight of 1.0-1.2, 1.5-1.7, 2.1-2.2, 2.5-2.7, 2.8-3.0 and 3.3-3.5 (i.e 24, 28, 34, 39, 42 and 48- day slaughter day). The results revealed that dressing and breast % were significantly (P<0.001) increased whereas the giblet % significantly decreased with increasing slaughter age. The cooking yield in chicken meat reflected an increasing trend after 2.1-2.2 kg broiler slaughter weight. L*, a* and b* values of meat were significantly increased with increased slaughter weight. Significantly highest water holding capacity was recorded in 3.3-3.5 kg slaughter weight.The shear force, H/L ratio, and serum corticosterone values were significantly increased from 1.0-1.2 kg to 3.3-3.5 kg in broiler birds. Once the birds attended the slaughter weight >2.1 kg, an increasing trend of gait score and breast cleanliness was observed at each stage of slaughter weight. Based on the results, the broiler birds reared up to 2.1 to 2.2 kg live body weight resulted in better welfare, immune status, and meat quality parameters.
