Five hundred seventy six layers of 50 weeks age, equally distributed in four groups, were reared in cages with 4 layers in each cage. A control diet was formulated. Three commercial enzyme preparations were supplemented to the control diet as per manufacturer's recommendations. Feed was offered ad lib to the birds in cages for three periods of 30 day each. Percent egg production and feed intake per bird were significantly (P<0.05) affected by the diets and periods. Periods also affected the feed consumption per egg. Significant (P<0.05) interaction between the diets and the periods for egg production, feed consumption per bird, feed, protein and ME consumption/egg were observed. Significantly (P<0.05) higher egg production with more feed intake was observed in birds fed diet T ₃ containing E₂ enzyme. Egg production was significantly (P<0.05) more in P₂ period. Feed, protein and ME intakes were significantly (P<0.05) more in P₂ and P₃ periods. It was concluded that the birds can perform better at lower enzyme concentrations and the enzymes which are to be supplemented in the diet should be substrate specific and the concentration of the enzymes should be optimum rather than as per the recommendation of manufacturer.
