波德代羊羊毛品质分析研究

Studies on Wol Qality of introduced Borderdale

通过对波德代羊毛纤维的自然毛丛长度、伸直长度、细度、强伸度的试验研究 ,表明 :成年波德代羊毛自然毛丛长度公羊为 17 0 8cm ,母羊为 14 79cm ;羊毛细度公羊为 3 1 9μm ,母羊为 2 8 3 7μm ;羊毛强度公、母羊分别为 3 5 13cN、3 3 73cN ;伸度公、母羊分别为 5 1 5 4%、5 1 91%;羊毛油脂率公、母羊分别为 12 5 1%、11 0 3 %;净毛率公、母羊分别为 68 2 6%、65 71%。

Experiment was carried out on wool quality of introduced Borderdale The results showed that the average woolcut were 9 49 kg±0 44 kg and 6 36 kg±0 92 kg for rams and ewes respectively; Wool grew fast , and the average speed of growth was 1 42 cm for ram,1 23 cm for ewe; Wool qulity was excellent Wool fineness was 31 90 μm for rams and 28 37 μm for ewes Grease content of wool was 12 51% for rams and 11 03% for ewes Wool strengths, stretched lengths and clean yield all came to or exceeded the standard of true type sheep
