摘　　要：选用21头35日龄、平均体质量(12.22±1.27)kg DLY(杜长大)断奶仔猪,随机分为3个处理,每处理7个重复,每个重复1头猪。3个处理分别为基础饲粮(Ⅰ组)、基础饲粮+2%竹炭(Ⅱ组)、基础饲粮+1%竹醋液(Ⅲ组),试验期为37 d,探讨竹炭和竹醋液对断奶仔猪生长性能、血液生理生化指标和抗氧化性能的影响。结果表明:(1)Ⅱ、Ⅲ组终末质量、ADG、ADFI和料重比与Ⅰ组相比差异不显著,但是Ⅲ组有提高断奶仔猪终末质量、ADG、ADFI,降低料重比的趋势(P>0.05),与Ⅰ组相比终末质量、ADG、ADFI分别提高了9.70%、14.74%、6.33%和料重比降低了7.17%。(2)添加竹炭和竹醋液对仔猪血液常规指标无显著性影响,但Ⅲ组的WBC、RBC、HGB、HTC、PLT均高于Ⅰ组。(3)在试验第15天,Ⅱ组LDH、AST显著高于Ⅰ组,Ⅲ组与Ⅰ组相比差异不显著。其他指标差异不显著。(4)在试验第15天,Ⅱ、Ⅲ组T-AOC与Ⅰ组相比显著升高;在试验第30天,Ⅱ、Ⅲ组MDA与Ⅰ组相比差异不显著,但Ⅲ组与Ⅰ组相比降低了27.68%(P>0.05),Ⅲ组显著低于Ⅱ组。结果提示:添加2%竹炭和1%竹醋液对断奶仔猪前期影响较大,后期影响较小;2%的竹炭含量可能过高,1%竹醋液有改善断奶仔猪生长和抗氧化性能及部分血液生理生化指标的趋势。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 （group I ）＇,basal diet＋2% bamboo carbon （group Ⅱ ） 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 group Ⅱ , Ⅲ and group I （P^0. 05）. Compared with group I , 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 group Ⅱ , Ⅲ and group Ⅰ ,but the WBC,RBC, HGB, HTC,PLT of group Ⅲ were higher than that of group Ⅰ （3） On day 15 of the experiment,the ac- tivity of LDH and AST of group Ⅱ was significantly higher than that of group I （P〈0. 05）, but there was no significant difference between group Ⅲ and group I . There were no significant differences of the other index. （4）The T-AOC of group Ⅱ and Ⅲ was significantly higher than that of group I （P〈0.05） on day 15 of the experiment. There was no significant difference of MDA between group Ⅱ ,Ⅲ and group I ,but decreased by 27.68% in group [[I compared with group I , 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
