Abstract: The present study was conducted to investigate the effect of fibrolytic enzyme on feed intake, growth performance and feed conversion ratio in Gir calves. Fifteen male Gir calves of around one year age was randomly selected and calves were randomly divided into three group with five calves in each for duration of 90 days. Three treatments were: only TMR (T₁), TMR supplemented with EFEs at 0.025% of DM (T₂) and TMR supplemented with EFEs at 0.050% of DM (T₃). Statistical analysis revealed that no significant effect was observed on DMI in both treatments. Whereas, DMI was numerically increased in both treatments as compared to control. TBWG (Kg) (63.6 & 62.1 vs. 52.4), ADG (g/d) (706.67 & 690.00 vs. 582.22) and FCR (8.01 & 8.19 vs. 9.24) were significantly (p<0.05) improved in both T₂ and T₃ as compared to T₁. Based on overall result EFEs were significantly improved ADG, FCR and TBWG.
