摘　　要：本试验采用2×5因子设计，研究日粮中不同水平刺槐叶粉水平（0％、10％、20％、30％、40％）对肉兔生产性能的影响及不同肉兔品种（哈尔滨白兔即H兔、丹麦白兔即D兔）对刺槐叶粉日粮的反应。选用30±2日龄断奶H兔95只、D兔85只，分别按体重、窝别、性别分成10个处理，每处理4重复。试验结果表明：10％～40％的刺槐叶粉用量对肉兔健康无影响且无适口性问题，但叶粉用量对肉兔生产性能有明显的负面剂量效应影响，即引起增重呈显著的三次曲线下降（R2＝0．85，P＜0．05）、采食量和饲料／增重呈极显著三次曲线上升（R2＝0．96、0．95，P＜0．01）。日粮中刺槐叶水平20％或20％以上，显著降低日增重、增加采食量（P＜0．05），极显著降低饲料效率（P＜0．01）。对刺槐叶粉日粮的耐受性没有品种差异（P＞0．15），日粮中叶粉配合比例以10％为宜。An 2×5 factorial experiment was conducted to examine： （1）the effect of gradient levels of commercial black locust（Robinia pseudoacacia L．） leaf meal （BLM） used in diets on growth performance of meat－type rabbits， （2） the response from different genotype rabbits（Harbin white rabbit， H and Danish white ranbbit， D） to diets including BLM． Ninety－five H rabbits，eighty－five D rabbits both weaning at 30±2 days of age were allotted to accept the diet treatments with an inclusion of 0％， 10％， 20％， 30％， 40％BLM， respectively， each treatment with 4 replicates． Results showed that the incorporation of 10％～40％ BLM into diets had no influence on both rabbit mortality and diet palatability，but a marked adverse effect on growth performance，namely that average daily body gain（ADG） was decreased following a cubic pattern（R2＝0．85，P＜0．05）， feed intake（FI） and feed conversion ratio（FCR）increased also both following a cubic pattern（R2＝0．96， P＜0．01 for FI， R2＝0．95， P＜0．01 for FCR） with increasing BLM level from 0％ to 40％． Compared to diet treatments with 0％ and 10％ BLM， 20％ inclusion of BLM and the above，significantly decreased ADG and increased FI （P＜0．05）， extremely elevated FCR （P＜0．01）． There was no difference on the tolerance to BLM diets between genotypes． It was recommended that BLM was formulated into growing rabbit diet at the level of 10％．
