摘　　要：选取35日龄体重较为一致的力克斯獭兔幼兔48只,随机分为4组(A、B、C、D),每组12只。在基础日粮和营养水平相同的情况下,试验组B、C、D分别在日粮中添加0.25%的不同品种青蒿提取物,A组为对照组。试验结果表明:①试验组D幼兔平均增重比对照组提高了17.73%,差异显著(P<0.05),料重比下降16.40%,差异达到极显著水平(P<0.01)。试验组B、C幼兔平均增重都高于对照组,但差异不显著(P>0.05),料重比显著下降(P<0.05)。②试验组D与对照组幼兔的半净膛率相比有提高的趋势,但差异不显著(P>0.05)。与对照组相比,试验组D的肝重/体重有所升高,脾重/体重有所下降,而血液生化指标都有下降的趋势。表明青蒿提取物对獭兔幼兔具有促生长、提高饲料报酬的作用,而对提高幼兔免疫能力影响不大。Forty eight rex rabbits were divided rabbits were 35 days old. The basic diet and the level into 4 groups at random with 12 rabbits per group, and the of nutrition were the same. Different varieties of sweet wormwood herb extracts were added at 0.25% in the diets of group B, C and D, respectively. Group A was the control. The results： ①Compared with the control, the average daily gain（ADG） of group D was increased by 17.73%（P〈 0.05）, and the feed/gain was decreased by 16.40%（P〈0.01 ）; the ADGs of group B, C were higher than control （P〉0.05）, and the feed/gain were significantly decreased（P〈0.05）; ②Eviscerated weights with giblets of group D was higher（P〉0.05）. The liver/body weight ratios were increased and the spleen/body weight ratios were decreased. But blood biochemical indices showed declining trend. All the results show that the sweet wormwood herb extracts can stimulate the growth performance of the young rabbits, but immunity was not be influenced.
