The effect of phytase as feed additive in low phosphorus diet on carcass characteristics of Giriraja birds was studied after 42 days of feeding trials, where feed and water were provided ad libitum. Experiment was conducted on 420 day-old Giriraja chicks procured from the Department of Poultry Science, Bangalore. Birds were wing banded, weighed and then assigned at random to seven dietary treatments (T1- T7) with four replicates (R1-R4) in each group with 15 chicks in each. Basal diet was formulated as per the recommendations of ICAR (2013) nutrient requirements, to which phosphorus and phytase were altered according to treatment groups. The basal diet Control (0.45% available P -T1), Low P diet (0.35% available P -T2), low P diet (0.3% available P -T3), Low P diet (0.35% available P + Phytase 500 FTU/kg-T4), Low P diet (0.3% available P + phytase 500 FTU/kg-T5), Low P diet (0.35% available P + Phytase 1000 FTU/kg-T6), Low P diet (0.3% available P + Phytase 1000 FTU/kg-T7) were fed to respective experimental group of birds. Birds were reared under deep litter system with all standard managemental practices in common till 42 days of feeding trial. The dietary supplementation of phytase on the carcass characteristics of Giriraja birds showed that addition of phytase enzyme in low phosphorus diet had significant comparable effect on dressing percentage, Liver percentage and heart percentage of birds under study whereas gizzard and abdominal fat percentage didn’t showed any significant difference.
