摘　　要：为研究转Bt玉米对五指山猪生长性能及器官指数的影响,评价其饲用安全性,选取2月龄遗传背景相近、初始体重(9.80±0.41)kg、健康断奶五指山猪72头,随机分为2处理组,每个处理6个重复,每个重复6头。分别饲喂含转Bt玉米(试验组)和非转基因玉米(对照组)的日粮。试验为期68 d,于68 d屠宰取样。结果表明:①试验组的末重、平均日增重、平均日采食量及料重比均与对照组间差异不显著(P>0.05);②两组的器官指数间也未达到显著差异的水平(P>0.05)。结果提示,转Bt玉米对生长期五指山猪的生长性能和器官指数未产生不良影响。In order to investigate the influences of genetically modified Bt maize on growth per-formance and organ indices of growing Wuzhishan pigs and to evaluate the safety, seventy-two2-month-old heahhy weaning pigs with average initial weight of （9.80＋0.41） kg and the similargenetic backgrounds were randomly divided into two treatments, 6 replicates of 6 pigs each.Pigs were fed with diets containing genetically modified Bt maize （experimental group） or non-genetically modified maize （control one） during the period of 68 days, respectively. Pigs wereslaughtered on 68 d for sampling. The results showed that： ① final weight, average daily gain,average daily feed intake and feed/gain ratio of experimental group were not significantly differ-ent from those of control one （P〉0.05）; ② there were no significant differences in organ indicesbetween the two groups （P〉0.05）. In conclusion, there were no adverse effects of geneticallymodified Bt maize on growth performance and organ indices of growing Wuzhishan pigs.
