Abstract:

A biological trial was conducted to study the effect of phytase supplementation on growth performance, egg production and quality traits in Swarnadhara breeders reared from 29 to 48 weeks at Department of Poultry Science, Veterinary College, Hebbal, Bengaluru. Thetrial had total 450 birds distributed to5 treatments of 90 each, treatment having three replicates, each with 30 birds. Control diet (T1) was formulated according to ICAR (2013) nutrient requirements and the groups T2 to T5 were formulated with changed non-phytate phosphorus levels so as to contain 0.12% in T2, 0.18% in T3, 0.12% NPP with 500IU/kg phytase in T4 and 0.18% NPP with 500 IU/kg phytase in T5. Weight gain, hen day egg production and feed efficiency per dozen of eggs produced are not significantly (P>0.05) affected by phytase supplementation. Shell weight and shell thickness were significantly (P <0.05) higher in phase IV in T4. Phytase supplementation at 0.12% NPP level with phytase improved the shell thickness and shell weight in Swarnadhara breeders. NPP level of 0.12% with phytase is optimum for Swarnadhara breeders to maintain egg production and egg quality. There was no additional advantage, however, of increasing the NPP concentration above 0.12% or adding phytase to the diet containing 0.18% NPP in Swarnadhara breeders.
