Description This study was conducted to evaluate the probiotic and exogenous fibrolytic enzyme treated rice straw on the performance of Heifers. Eighteen heifers were selected and allocated into three groups having six animals in each and fed treatment diet for 120 days. The control group was fed on basal diet whereas, group-1 was supplemented basal diet with 5g/kg probiotic (Saccharomyces cerevisiae) and group-2 was supplemented basal diet with 7g/kg exogenous fibrolytic enzymes (EFE). The nutrient requirements of heifers were met by feeding concentrate mixture, Jowar, and paddy straw (50:30:20 ratio) on DM basis. No effect on DMI, FCR, FCE but body weight gain was found significantly higher (P<0.05) in supplemented group. There was no significant effect (P<0.05) of supplementation 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, plasma globulin, plasma cholesterol, plasma 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.  There was no significant effect on plasma minerals except P and Se. there was no effect on animal behaviour parameters after supplementation but rumen enzyme i.e., cellulase, avicelase, and xylanase activity in EFE group showed significantly higher (P<0.05) than probiotic or control group. Finally, it may be concluded that probiotics (Saccharomyces cerevisiae) and exogenous fibrolytic enzyme @ 5 and 7 g per kg DM, respectively improved weight gain and digestibility of nutrients without affecting blood haematology, biochemical parameters, mineral profile and ingestive behaviour adversely. Thus, rice straw may be included in ration of ruminant up to 20% of DM with probiotics (Saccharomyces cerevisiae) and exogenous fibrolytic enzyme treatments.
