| 摘 要： | 本研究选择甘肃皇城羊场成年甘肃高山细毛羊母羊200只,随机分成两组,试验组穿上特制的绵羊罩衣,对照组不作任何处理,相同条件下饲养管理到第二年春季测定羊毛品质指标。结果表明,试验组平均羊毛长度比对照组长0.29 cm,差异显著(P<0.05);羊毛细度试验组与对照组相差仅0.7μm,差异不显著(P>0.05);羊毛油汗长度试验组比对照组长2.76cm,差异极显著(P<0.01);毛丛污染深度,试验组比对照组污染深度短2.46 cm,差异极显著(P<0.01);羊毛脂和汗质的含量试验组比对照组分别提高55%和16.5%,差异均极显著(P<0.01);羊毛中杂质含量对照组杂质含量比试验组高20.47个百分点,差异极显著(P<0.01);毛束强度试验组仅比对照组毛束强度偏低2.22N/kt(P>0.05)。

| Abstract: | Two hundreds of Gansu Alpine Merino were selected from Huangcheng sheep farm in Gansu province were divided into two groups randomly,and the sheeps of trail group were worn sheep overclothes and no any treatment for control group.The wool qualities of all individuals were measured in next spring under the same management and feeding conditions.The results indicated that the average wool staple length of treatment group(7.56 cm)was longer than that of control group(7.27 cm);The difference(0.7 micron) of average fineness of fiber between treatment group with control group is not significant(P>0.05);The difference(2.76 cm) of average wool grease and perspiration length between treatment group with control group is very significant(P<0.01);The average polluted depth treatment group was shorter(2.46 cm than that of control group and the difference is very significant(P<0.01);The average wool grease weight) and perspiration percentage of treatment group were increased 55% and 16.5% than that of control group and the difference is significant(P<0.01);The average impurity weight of treatment group was increased 212% than that of control group and the difference is significant(P<0.01);The difference of average staple strength between treatment group with control group is not significant(P>(0.05).) |
