Abstract: An experimental study was conducted to assess the impact of phytase enzyme supplementation on, carcass characteristics and visceral organ weights in 120 Cobb broilers over a period of 42 days. The study comprised four distinct dietary treatments they are control group T₁ (0.45% available phosphorus) as per Bureau of Indian standards 2007, low phosphorous diet T₂ (0.35% available phosphorus + 0.01% Phytase 5000 FTU), low phosphorus diet T₃ (0.30% available phosphorus + 0.02% Phytase 5000 FTU) and low phosphorus diet T₄ (0.25% available phosphorus + 0.03% Phytase 5000 FTU). The result revealed that there is no significant difference (p>0.05) in carcass traits like dressing percentage, thigh yield, breast yield, drumstick yield, abdominal fat percentage and visceral organs like heart, liver, proventriculus and gizzard between control group and phytase supplemented low phosphorus groups and also among phytase supplemented low phosphorus groups. In conclusion, the phytase supplementation in low phosphorous diet may not affect the percent live weight of carcass traits and visceral organs.
