摘要
小尾寒羊1997年4月引入四川会理县,经一年多饲养试验.引种羊存活率91.3%,情期受胎率84.7～87.5%,产羔率180.33～185.77%.三月龄平均体重18.5±0.20kg.平均日增重176.85±4.41g,体长55.3±1.6cm,胸围60±1.1cm,体高57.6±0.4cm。六月龄体重31.6±1.3kg,平均日增重144.42±10.8g.体长67.7±0.60cm,胸围74.4±11.40cm,体高68.4±0.9cm。上述指标接近中国农业大学养羊研究室在良好条件下的生产性能指标。
Huili Han sheep were imported from Shandong Province.More than one year's feeding experiment has shown that:their surviving rate was 91.3%,pregnancy rate 84.7 ～87.5%,lambing rate 180.33～185.77;their mean boldy weight of 3 months'18.5±0. 2kg,mean daily weight gain 176.85±4.41g,body height 57.6±0.4cm, brest length 60±1.1cm;their mean body weight of 6 months'31.6±1.3kg, mean daily weight gain 144.2±10.8g,body length 55.3±1.6cm,body length 67.7±0. 60em,brest length 74.4±1.40cm,body height 68.4±0.9cm.All above mentioned index- es are nearly the same as the production standard indexes,set up by the Research Group of Raising Sheep of the Agricultural University of China.
