This study evaluated the probiotic and exogenous fibrolytic enzyme (EFE) treated rice straw on the performance of Hariana heifers. Animals were allocated into three groups having six animals and fed diet for 120 days. The control group was fed on basal diet whereas, group-1 was supplemented basal diet with 5g/kg DM probiotic and group-2 was supplemented basal diet with 7g/kg DM EFE. The nutrient requirements of heifers were met by feeding concentrate, Jowar, and paddy straw (50:30:20 ratio) on DM basis. No effect on DMI,Feed conversion ration (FCR) or Feed conversion efficiency(FCE) but body weight gain was significantly higher (P<0.05) in supplemented group.There was no significant effect (P<0.05) on blood parameters except Hb and HCT levels which was significantly higher in the treatment groups. Treatment groups showed significantly higher (P<0.05) plasma total protein, globulin, cholesterol, ALP and lower bilirubin whereas, no significant effect (P>0.05) was found on albumin, glucose, triglycerides, ALT, AST,creatinine and PUN levels. BHBA and IGF-1 were similar in all group but NEFA, FRAP and SOD were significantly different (P<0.05) in control, probiotic and EFE group, respectively. No effect on plasma minerals except P and Se.there was no effect on animal behavior parameters but rumen enzyme i.e., cellulase, avicelase, and xylanase activity in EFE group showed significantly higher (P<0.05). Finally, it may be concluded that probiotics (
