摘　　要：本试验旨在研究茶叶渣替代麸皮对肉兔生长性能、屠宰性能和肉品质的影响。试验选择28日龄体重相近的新西兰兔480只,随机分成4个组,每组5个重复,每个重复24只(公母各占1/2)。对照组饲喂基础饲粮,试验组分别以10%、15%和20%茶叶渣替代等比例麸皮。预试期7 d,正试期42 d。结果表明:1)与对照组相比,10%茶叶渣替代组的终末体重、平均日增重、平均日采食量、料重比、腹泻率和死亡率无显著差异(P>0.05);20%茶叶渣替代组的终末体重、平均日增重、平均日采食量显著下降(P<0.05),且料重比显著升高(P<0.05)。2)与对照组相比,10%茶叶渣替代组的宰前活重、全净膛重和半净膛重无显著差异(P>0.05),但15%和20%茶叶渣替代组的宰前活重、全净膛重和半净膛重显著降低(P<0.05)。3)与对照组相比,10%和15%茶叶渣替代组的肌肉pH24 h和滴水损失无显著差异(P>0.05);20%茶叶渣替代组的肌肉pH24 h显著降低(P<0.05),且肌肉滴水损失显著提高(P<0.05)。4)与对照组相比,10%和15%茶叶渣替代组的肌肉水分、粗蛋白质和粗脂肪含量无显著差异(P>0.05),但20%茶叶渣替代组的肌肉粗脂肪含量显著降低(P<0.05)。综上所述,在肉兔饲粮中以10%茶叶渣替代等比例麸皮对肉兔的生长性能、屠宰性能和肉品质无不利影响。The purpose of this experiment was to explore the effects of wheat bran replacement by tea leaf residue on growth performance,slaughter performance and meat quality of meat rabbits. A total of 480 New Zealand rabbits with similar body weight at the age of 28 days were randomly divided into 4 groups with 5 replicates in each group and 24 rabbits in each replicate(half male and half female). Rabbits in the control group were fed a basal diet,and others in experimental groups were fed diets which used 10%,15% and 20% tea leaf residue substitute equal proportion wheat bran,respectively. The pre-feeding period was 7 days,and the trial period was 42 days. The results were showed as follows:1)compared with the control group,the final body weight,average daily gain,average daily feed intake,feed to gain ratio,diarrhea rate and mortality rate of10% tea leaf residue substitution group were no significant difference(P>0.05);the final body weight,average daily gain and average daily feed intake of 20% tea leaf residue substitution group were significantly decreased(P<0.05),and the feed to gain ratio was significantly increased(P<0.05). 2)Compared with the control group,the pre-slaughter body weight,all carcass weight and half carcass weight of 10% tea leaf residue substitution group were no significant difference(P>0.05),while the pre-slaughter body weight,all carcass weight and half carcass weight of 15% and 20% tea leaf residue substitution groups were significantly decreased(P<0.05). 3)Compared with the control group,the muscle pH24 hand drip loss of 10% and 15% tea leaf residue substitution groups were no significant difference(P>0.05);the muscle pH24 hof 20% tea leaf residue substitution group was significantly decreased(P <0.05),and the drip loss was significantly increased(P<0.05). 4)Compared with the control group,the contents of moisture,crude protein and ether extract in muscle of 10% and 15% tea leaf residue substitution groups were no significant difference(P>0.05),while the muscle ether extract content of 20% te
