摘 要: | 目的]探讨细毛羊罩衣对绵羊羊毛纤维产量和质量的影响。方法]以聚氯已稀为主要原料,制成不同型号的羊罩衣,在绵羊剪毛后给绵羊穿上,来年剪毛时脱下。研究细毛羊罩衣对羊毛被毛结构、羊毛纤维产量、羊毛纤维品质、羊毛油汗、羊毛净毛率和杂质、羊毛毛纺加工的影响。结果]绵羊穿上罩衣1年后,个体羊毛纤维长度平均增长0.33 cm(P<0.05),净毛率提高12.44个百分点(P<0.01),净毛产量提高0.44 kg(P<0.01),羊毛中油脂含量提高6.44个百分点(P<0.01),毛丛污染深度下降3.10 cm(P<0.01),灰尘含量下降21.25%(P<0.01)。结论]绵羊穿上罩衣后,明显改善了羊毛纤维的质量,提高了绵羊的生产性能。

Abstract: | Objective] To explore the effects of coats on production and quality of wool fibers in fine-wool sheep.Method] The coats made of polypropylene were put on fine-wool sheep after shearing and taken off next year.The effects of coats on structure,production and quality of wool fibers,sticky sweat secretion,rate of clean wools,impurities and wool textile process in fine-wool sheep were observed.Result] After the sheep were dressed one year later,the average fiber length was increased by 0.33 cm(P<0.05);the rate of clean wools was increased by 12.44%(P<0.01);the yield of clean wools were increased by 0.44 kg(P<0.01);the grease content was increased by 6.44%(P<0.01);the polluted staple length was decreased by 3.10 cm(P<0.01);and the dust content was decreased by 21.25%(P<0.01).Conclusion] Coats remarkably improve quality of wool fibers and production performance in fine-wool sheep. |
