摘　　要：近年来，在貉的品种培育过程中，发现了黑色突变个体（简称黑貉），作为一种新的突变品种，黑貉有着极大的科研和利用价值。为了解其生物学特性，本试验以乌苏里貉为对照，分别对黑貉繁殖性能、生长性能、毛皮性能、血液生理生化指标进行了测定。结果表明，在相同的饲养和管理条件下，黑貉和乌苏里貉窝产仔数和分窝成活率差异不显著（P〉0．05）；生长性能中，不同毛色个体45～210日龄体质量和体高差异不显著（P〉0．05）；毛皮性能中，黑貉背部针绒毛长度显著高于乌苏里貉（P〈0．05）；血液生理生化指标中，除了同种色型问个别指标有差异外，其他各项指标在2种毛色貉闯无统计学差异（P〉0．05）。The black mutant raccoon dog （black raccoon dog）, as a new mutant, has great value in scientific research and utilization. To understand its biological characteristics, the growth perform- ance,fur performance and blood physiological and biochemical indexes of black raccoon dog were determined, and compared with the normal raccoon dog. The results showed that there was no sig- nificant difference in the litter size and survival rate between black raccoon dog and normal raccoon dog in the same feeding and management conditions （P〉0.05）. In the growth performance,the body weights of 45-210 days were no significant difference （P〉0.05）. In the fur performance,the length of needle and villi of black raccoon was significantly higher than that of normal raccoon dog （P〈0.05）. The physiological and biochemical indexes of blood were not significantly different （P〉0.05）.
