摘　　要：为了解决鉴别野生和饲养动物来源的技术问题,以环颈稚为研究对象,测定了野生(n=55)和人工饲养的环颈雉(n=50)的胫骨和跗蹠骨的长度和密度(CT值),并借此建立鉴别方法。结果表明:在野生组和饲养组之间胫骨和跗蹠骨的长度比例(|t|=4.200,P=0.000)和CT平均值(|t胫|=5.053,|t跗蹠|=3.819,P=0.000)都存在极显著差异,可以有效鉴别环颈雉的来源。在忽略性别因素时,联合使用胫骨和跗蹠骨的CT值进行判别,整体上判别准确率能达到82.7%,野生环颈雉的正确判别率为83.3%(45/54),人工饲养的环颈雉为82.0%(41/50)。区分性别时,雄性单独使用胫骨长度比例鉴别力可以达到79.5%,若与CT值联合可以达到84.6%。该方法也适用于活体动物的检测,可以实现无损伤检验。In order to solve the technical problems of identifying the origin of wild and farmed animals,the length and density of tibia and tarsometatarsus(CT value)of wild(n=55)and cultured(n=50)pheasants were determined in this study.The results showed that the proportion of tibia and tarsometatarsus(ltl=4.200,P=0.000)and the mean CT value(ltl=5.053/-3.819,P=0.000)were significantly different between the wild group and the farm group,which could be used to identify the source of the pheasant.The results also showed that the combination of the tibia and tarsometatarsus without gender discrimination had the highest overall accuracy of 82.7%,correctly classifying 83.3%(45 out of 54)wild pheasants and 82.0%(41 out of 50)farm pheasants.The proportion of tibia was 79.5%for males alone and 84.6%for males when combined with CT value.This method is also suitable for non-damage detection in live animals.
