摘　　要：采集欧拉型藏羊的睾丸及附睾,对其不同区段内精子的形态指标进行观察。结果显示:睾丸及附睾不同区段的精子密度依次为:睾丸1.05╳10^7个/mL、附睾头4.31╳10^7个/mL、附睾体2.13╳10^7个/mL、附睾尾1.42╳10^8个/mL;精子畸形率分别为:睾丸14.18%、附睾头15.13%、附睾体15.7%、附睾尾15.20%;顶体完整率分别为:睾丸70.15%、附睾头70.09%、附睾体71.53%、附睾尾70.76%。结果表明,欧拉型藏羊睾丸、附睾中精子密度、顶体完整率较低,可能与藏羊所处环境中日粮、环境温度等有关,但其精子畸形率符合受精标准。The experienment collected semen in testis and epididymis of Oura-type Tibetan sheep and sperm morphological parameters in different locations were observed. The results showed the sperm densities were 1.05╳10^7/mL in testis, 4.31╳10^7/mL in head of epididymis, 2.13╳10^7/mL in body of epididymis an d 1.42╳10^8/mL in tail of epididymis;the sperm deformity rates were 14.18% in testis, 15.13% in head of epididymis, 15.7% in body of epididymis and 15.20% in tail of epididymis;the acrosome integrity rates were 70.15% in the testis, 70.09% in the epididymis head, 71.53% in the epididymis body and 70.76% in tail of epididymis. The results illustrated that the sperm densities and acrosome integrity rates in the testis and epididymis of the Oura-type Tibetan sheep were lower than results reported in other breeds, so it may account for the different feed and low temperature in which Oura-type Tibetan sheep have lived, but the sperm deformity rates were in accordance with the fertilization standard.
