Abstract: The present study was conducted to evaluate the effect of phytase enzyme supplementation at varying dietary energy levels on the growth performance of Pratapdhan chicks (day-old) were used in a completely randomized design in 5 treatments with 4 replicates, each consisting of 10 chicks. The treatment comprised of T₁ Control basal diet (CP 20% and ME 2800 kcal/kg), T₂ (Control diet + supplemented with Phytase @1500 FTU/Kg, T₃ (T₂ + 5% reduction in ME), T₄ (T₂ +10% reduction in ME) and T₅ (T₂ +15% reduction in ME). The effect of supplementation of phytase enzyme was studied on body weight and body weight gain of Pratapdhan chicks were measured. At the age of 8^th week body weight was significantly highest (p<0.05) in T₃ followed by T₂, T₁ and lowest in T₅ group. Overall body weight gain was significantly highest (p<0.05) in T₃ followed by T₂, T₁, T₅ and T₄ group. It may be concluded that the feeding of Phytase enzyme is beneficial in improving body weight and body weight gain of Pratapdhan chicks.
