优质细毛羊与中国美利奴羊生长发育及生产性能对比试验初报

Comparison Experiment of Growth and Development and Output Performance Between Quality Fine Wool and Chinese Merino Sheep

摘要:

优质细毛羊是近几年在进口羊基础上经选育扩繁形成的国内最新的品种群。为了有效地开发这一品种,了解该品种的生产性能水平及其在同类品种中所处的地位是十分必要的。本试验通过与国内最具代表性的中国美利奴羊采用同期同龄同环境饲养的对比方法,进行了两品种间对比试验,得出初步结果,中国美利奴羊在生产发育、毛量、毛长和羊毛生长等性状较为突出,体现了强毛型品种特征,而优质细毛羊在羊毛品质性状方面较为突出,尤其是细度在66～80支纱范围,比中国美利奴羊高出一个档次,具有明显的细型美利奴品种特征。
