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。
[ 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 I 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 ）. [ Con- clusion] Coats remarkably improve quality of wool fibers and production performance in fine -wool sheep.
