Abstract

Present study was conducted to compare welfare and associated meat production performance and quality of broiler in open sided conventional broiler house (OSCBH) with floor space allowance of 1.0/ft2 per chick and in tunnel ventilated environment control broiler house (ECBH) with reducing floor space of 1.0, 0.9, 0.8, 0.7and 0.6 ft2 per chick. Average body lesions score, indicating physical injury and welfare were well within the acceptable limits of European welfare quality protocol. Stress related anti-oxidant enzyme (Glutathione peroxidase, Lipid peroxidation, Superoxide dismutase, Catalase and Glucose-6-phosphate dehydrogenase) concentrations were higher in OSCBH (T0)) than ECBH (T1, T2, T3, T4 and T5). However percent eviscerated carcass and prime cuts did not decreased significantly (p≤ 0.05) in ECBH at higher stocking densities but meat yield per unit floor area was around 90 % higher even at 40% reduction of floor allowance.
