A total of 21 crossbred (Duroc×Landrace×Large white) weaned piglets with an average body weight of (12.22±1.27) kg were randomly assigned into 3 groups with 7 replicates per group and 1 piglet in each replicate．The 3 groups were as the following：basal diet (groupⅠ),basal diet+2％ bamboo carbon (groupⅡ) and basal diet + bamboo vinegar 1％(group Ⅲ)．The experiment lasted for 37 d．This experiment was conducted to study effects of bamboo-carbon and bamboo vinegar on growing performance,physiological and biochemical indexes of blood and antioxidant capacity of weaned piglets.The results showed that：(1)There were no significant differences of final weight,ADG,ADFI,the ratio of feed to gain between groupⅡ,Ⅲ and groupⅠ(P>0.05).Compared with groupⅠ,final weight,ADG,ADFI in group Ⅲ,had a ascendant trend,increasing with 9.70%,14.74%,6.33% (P>0.05),respectively,while the ratio of feed to gain had a downtrend (P>0.05),decreasing by 7.17%.(2) There were no significant differences of hematologic indexes between groupⅡ,Ⅲ and groupⅠ,but the WBC,RBC,HGB,HTC,PLT of group Ⅲ were higher than that of groupⅠ.(3) On day 15 of the experiment,the activity of LDH and AST of groupⅡ was significantly higher than that of groupⅠ(P<0.05),but there was no significant difference between group Ⅲ and groupⅠ．There were no significant differences of the other index.(4）The T-AOC of group Ⅱ and Ⅲ was significantly higher than that of groupⅠ(P<0.05) on day 15 of the experiment.There was no significant difference of MDA between groupⅡ,Ⅲ and groupⅠ,but decreased by 27.68% in group Ⅲ compared with groupⅠ,and was significantly lower than in group Ⅱ.In conclusion,the effects of bamboo-carbon and bamboo vinegar on weaned piglets were more obvious in the early growing period (1-15 d) than in the later growing period (16-37 d).Addition of 2% bamboo-carbon may be too high and the addition of 1% bamboo vinegar can improve the growth performance,physiological,biochemical indexes of blood and antioxidant performance of weaned piglets.
