Studies revealed that at stocking density of 1.0 sq. ft/ bird, various growth parameters viz. body weight (2244.83±97.29 g), weight gain (614.22±99.97 g) and feed conversion ratio (1.88±0.004) were significantly higher (P<0.05). The feed consumption (1295.91±0.30 g/bird/week) were also significantly higher (P<0.01) at above mentioned stocking density. Among the different biochemical and haematological parameters, significant findings (P<0.05) were observed at stocking density of 1.25 sq. ft/ bird for % calcium retention (59.07±3.34%) and serum cholesterol (114.37±3.33 mg/dl). However, the glutahione (mole/g Hb) and lipid peroxidation (mole/g Hb) activity were found to be significant (P<0.05) at 0.75 and 1.0 sq. ft/ bird floor space respectively. At floor space of 1.0 sq. ft/ bird, the lowest mortality and highest benefit cost ratio were observed and thus found to be most adequate for maximum productivity of broilers raised in summer season.
