| 摘 要： | 利用南非肉用美利奴羊与东北细毛羊杂交,构建了东北细毛羊肉用类型群,并进行了生长与屠宰性状、肉质性状和毛用性状的检测与评定。结果表明:杂交羔羊适于舍饲强度育肥,对高营养水平反应敏感,平均日增重>180 g,屠宰率>45％;成年母羊羊毛细度23 μm,羊毛长约13 cm,毛用性状与东北细毛羊差异不显著。

| Abstract: | Based on wool keeping mutton increasing strategy, northeast fine wool sheep meat population, developed from South Africa mutton merino×northeast fine wool sheep, was detected and assessed in lamb growth and slaughter traits, meat traits and wool traits. The results indicated that intensity fattening is suitable for crossbred lambs in housing fattening manner; It is sensitive to high nutritional level; Average daily gain is above 180 g; Dressing percentage is morethan45％; Wool fibre diameter is 23 μm and wool length is 13 cm in adult female sheep. Compared with northeast fine wool sheep, the difference in wool traits is not significant. |
