520 |a Objective: This study was conducted to evaluate the effects of tannins and cellulase on growth performance, nutrient digestibility, blood profiles, intestinal morphology and carcass characteristics in Hu sheep 
520 |a Methods: A total of 48 three-month-old meat Hu sheep (25.05 ± 0.9 kg) were blocked based on body weight, and randomly allotted to 4 treatments with 3 replicates of 4 sheep each. The experiment lasted for 80 d, and dietary treatments were as follows: (1) CON, control diet; (2) TAN, CON + 0.1% tannins; (3) CEL, CON + 0.1% cellulase; (4) TAN+ CEL, CON + 0.1% tannins and 0.1% cellulase 
520 |a Results: Compared with CON, CEL and TAN+CEL had greater (P<0.05) final birth weight (FBW) and average daily gain but lower (P<0.05) F/G, while FBW of TAN+CEL was lower (P<0.05) than that of CEL. The apparent total tract digestibility (ATTD) of DM in TAN, CEL and TAN+CEL groups were higher (P<0.05) than that in CON. CEL and TAN+CEL groups had greater (P<0.05) ATTD of CF compared with TAN and CON, while TAN group had lower (P<0.05) ATTD of CP than other treatments. TAN, CEL and TAN+CEL groups increased (P<0.05) serum globulin and alkaline phosphatase but decreased (P<0.05) A/G. Serum total protein was greatest for TAN+CEL, intermediate for TAN and CEL and least for CON (P<0.05). TAN+CEL group increased (P<0.05) dressing percentage compared with CON, while the backfat thickness of CEL was lower (P<0.05) than that of CON. The villus height of jejunum and ileum in CEL and TAN+CEL groups were greater (P<0.05) than that in CON, and the crypt depth and villus height: crypt depth of jejunum were increased (P<0.05) in TAN, CEL and TAN+CEL groups 
520 |a Conclusion: The addition of tannins and cellulase together promoted nutrient digestion, liver protein synthesis and intestinal development and thus improved growth performance and carcass characteristics
