周岁彭波半细毛羊羊毛品质分析

Wool Quality Appraisal of One Full Year Pengbo Semi-fine Wool Sheep

为了解彭波半细毛羊的羊毛品质,随机选择1周岁的彭波半细毛羊公羊7只,母羊21只,采集其肩部、体侧和股部羊毛,统计分析平均纤维直径、洗净率、毛丛自然长度、卷曲度、伸直率和油汗比例等指标。结果表明,周岁公羊的肩部羊毛纤维直径显著低于母羊(P<0.05),公羊各部位羊毛毛丛自然长度极显著低于母羊(P<0.01),公羊肩部羊毛卷曲度极显著高于母羊(P<0.01),公羊各部位羊毛的油汗比例极显著低于母羊(P<0.01)。综上,彭波半细毛羊的羊毛品质较好,但其色度和公羊的毛丛自然长度仍有改善的空间。

To study the wool quality of Pengbo semi-fine wool sheep,7 male and 21 female Pengbo semi-fine wool sheep at the age of 1 were randomly selected to collect their shoulder,body side,and thigh wool,and statistical analysis was conducted on average fiber diameter,washing rate,natural length of wool clump,curl,straightness,and grease ratio.The results showed that the diameter of wool fibers in the shoulder of one year old male sheep was significantly lower than that of female sheep(P<0.05),and the natural length of wool clumps in each part of male sheep was significantly lower than that of female sheep(P<0.01).The curl of wool on the shoulders of male sheep was significantly higher than that of female sheep(P<0.01),and the grease ratio of wool in each part of male sheep was significantly lower than that of female sheep(P<0.01).In summary,the wool quality of Pengbo semi-fine wool sheep is good,but there is still room for improvement in wool color and the natural length of the ram's wool tuft.
