摘　　要：测定分析了新疆地区引入澳大利亚萨福克羊及无角陶塞特羊的体温、脉搏、呼吸频率、血清T3、T4 含量、繁殖率、总适应能力及杂一代公羔的育肥屠宰性能 .结果表明 ,萨福克羊及无角陶塞特羊繁殖率及体重接近或超过原产地澳大利亚的生产水平 .萨福克羊总适应能力为 98.80 % ,无角陶赛特羊为 98.74% .杂一代公羔日增重、饲料转化率、净肉重较哈萨克羊高 。The physiological characters,reproductive rate and comprehensive adaptability of Suffolk sheep and Polled Dosert sheep introduced from Australia to Xinjiang Region were measured.The results showed that the Suffolk sheep and the Polled Dosert sheep were similar or higher than those in Australia in productive rate,and body weight.The comprehensive adaptability of Suffolk sheep and Polled Dosert sheep were 98.80% and 98.74%,respectively.The performance of fattening,slaughtering of F 1 of Suffolk and Polled Dosert sheep with Kasak sheep were better than that of Kazak sheep.
