假苍耳喂饲幼兔试验研究

将入侵植物假苍耳（Iva xanthifolia）粉碎后与常规预混原料按照比例（以质量百分比计）：假苍耳草粉50%、玉米粉11%、豆饼粉20%、麦麸9%、鱼粉3%、骨粉5%、酵母粉1%、食盐1%混合制备成颗粒饲料，分别以相当于假苍耳含70、60、50、40 g等4个实验组和对照组喂饲常规饲料，每天喂饲幼兔。室内单笼60 d饲养后，分别进行血清学检验、血常规检验、解剖实验及增重效果评价，探讨假苍耳对幼兔适口性和毒性的影响，以及不同假苍耳含量的配合饲料对幼兔生长性能的影响。实验结果表明，假苍耳适口性良好、无毒性症状，各项测定数据无显著差异，从饲用价值角度来说，假苍耳代替部分幼兔饲料是可行的。

Experiment Study on Iva xanthifolia to Feed Young Rabbit

The crashed invasive plant Iva xanthifolia and routine premix composition were mixed according to the proportion (quality percentage) as followed: I. xanthifolia weed flour 50%, maize flour 11%, bean cake flour 20%, wheat bran 9%, fish flour 3%, bone meal 5%, yeast flour 1% and table salt 1% to prepare pellet forage. It was divided into control group that the young rabbits were fed routine pellet forage, and four experiment groups which containing I. xanthifolia weed flour 70, 60, 50, 40 g. Every group young rabbits were bred in single cage for 60 days. Our experiment adopted serology analysis, blood routine analysis, anatomy experiment and increase weight effect to investigate the palatability and toxicity of I. xanthifolia for young rabbits, and the young rabbit growth performance for containing different I. xanthifolia weed flour. The results showed that I. xanthifolia had better palatability and no toxicity symptom, and there were no significant differences for all the evaluation dates. On the opinions of feeding value, I. xanthifolia was feasible to substitute parts of young rabbit forage.
