| 摘 要： | 细毛羊高弯腹毛面积的大小对其主要经济性状和羊毛品质的影响与年龄有关,也即随细毛羊生长发育阶段不同而不同。育成羊(1.5岁)和青年羊(2.5岁以内)时期,高弯腹毛对体重、毛长、毛量三大经济性状和羊毛品质的影响不大。但成年以后则表现为对体重、毛长、毛量及沖度的影响较大。分析证明,3.5岁以上的成年母羊,腹毛高弯面积在1.5cm×1.5cm以上时,体重较大,自然毛长变短。腹毛高弯面积为10cm×10cm和15cm×15cm以上的净毛量降低,伸度减小,对细度和强力的影响不大。

| Abstract: | The influence of the area of high-crimped abdominal fibre (HCAF) in finewool sheeps on the main economic traits and wool quality related to its ages.The influence of HCAF in the stages of the ewe lambs (less than 1.5 ages) and of youth (less than 3.5 ages) was not great on the three important economic traits (body weight, wool length and Wool quality) and wool characterristies. The sheep had great influence upon their body weight, wool length, wool quantity and wool stretch when grew up. |
