| 摘要: |
| 研究了安哥拉山羊与陕北土种山羊杂交一代(F1)周岁母羊的产绒特性。结果表明,①F1绒自然长度和伸直长度分别为9.13, 10.69 cm,明显比陕北土种山羊绒长;②F1皮肤次级毛囊密度为2 521个/cm2,明显高于陕北土种山羊1 486个/cm2,低于陕北绒山羊2 987个/cm2;③F1绒纤维直径平均为18.09μm,粗于陕北土种山羊11.35μm和绒山羊14.73μm;④产绒量F1为271.00 g,显著高于陕北土种山羊103.57 g和陕北绒山羊166.35 g。 |

| Abstract: |
| Down-producing characteristics of F1(Angora×localgoat) yearling does were studied in this paper.The results were as follows: (1) The stretched length (10.69cm) and natural length (9.13cm) of F1 down fiber were much longer than that of North Shaanxi local goat and cashmere goat; (2) The density of secondary follicle (2 521cm2)of F1 was much more than that of local goat (1 486 cm2), but was less than that of cashmere goat (2 987cm2); (3) The average fibre diameter (18.09μm) of F1 was much thicker than that of local goat (11. 35μm) and cashmere goat (14.73μm); (4) The down yield of F1(271.00 g)was more than that of local goat (103.57 g) and cashmere goat (166.35 g). |
