摘要: 旨在进一步阐明阿旺绵羊种质资源特征,为制定阿旺绵羊羊毛生产与质量控制标准提供科学依据。采用现场鉴定和实验室检测方法对270份采集自不同年龄、不同性别阿旺绵羊不同部位的羊毛样品品质进行分析研究。现场测定结果表明:阿旺绵羊成年公、母羊的平均羊毛长度分别为90.3、71.0 mm,平均剪毛量分别为1.35、1.00 kg;育成公、母羊平均羊毛长度分别为61.5、58.3 mm,平均剪毛量分别为1.08、0.84 kg;阿旺绵羊油汗颜色为白色或乳白色,油汗含量以1/2、1/3为主。实验室检测结果表明:成年公羊肩、侧、股3个部位毛长度分别为95.40、99.68、115.44 mm,成年母羊肩、侧、股3个部位毛长度分别为65.72、62.39、83.06 mm;育成公羊肩、侧、股3个部位毛长度分别为80.52、86.11、103.63 mm,育成母羊肩、侧、股3个部位毛长度分别为62.95、64.53、78.95 mm;采自3个不同部位的270份羊毛样品的纤维类型平均占比分别为:无髓毛占72.98%,有髓毛占21.31%,两型毛占5.47%;无髓毛平均直径为25.97 μm,直径离散26.79%;有髓毛平均直径为69.59 μm,直径离散23.63%;两型毛平均直径为41.99 μm,直径离散26.65%;粗毛纤维直径范围为24.66-72.15 μm,肩、侧、股部的纤维直径变化无规律。

Abstract: In order to further elucidate the characteristics of germplasm resources of Awang sheep and and to provide scientific basis for the healthy development of wool production and quality control standards of Awang sheep, a total of 270 wool samples collected from different parts of Awang sheep with different ages and genders were analyzed by field identification and laboratory detection. The results of field identification showed that the average wool length of adult rams and ewes was 90.3 mm and 71.0 mm, respectively, and the average wool yield was 1.35 kg and 1.00 kg, respectively; the average wool length of the growing rams and ewes was 6.15 cm and 5.83 cm, respectively, and the average wool yield was 1.08 kg and 0.84 kg, respectively; sticky sweat was white or milky white, and the content was mainly 1/2 and 1/3. The results of laboratory detection showed that the wool length of shoulder, flank and thigh of adult rams were 95.40 mm, 99.68 mm and 115.44 mm, respectively, and the wool lengths of shoulder, flank and thigh of adult ewes were 65.72 mm, 62.39 mm and 83.06 mm respectively; the wool lengths of shoulder, flank and thigh of growing rams were 80.52 mm, 86.11 mm and 103.63 mm respectively, and wool length of shoulder, flank and thigh of growing ewes were 62.95 mm, 64.53 mm and 78.95 mm respectively. The fiber types of 270 wool samples from three different parts were unmyelinated wool, medullated wool and both unmyelinated and medullated wool, accounting for 72.98%, 21.31%, 5.47%, respectively; the average diameter and discrete diameter of the unmyelinated wool were 25.97 μm, 26.79%; the average diameter and discrete diameter of the medullated wool were 69.59 μm, 23.63%; the average diameter and discrete diameter of the both unmyelinated and medullated wool were 41.99 μm, 26.65%; the diameter of the coarse fiber was in the range of 24.66-72.15 μm, and the variation fiber diameter of the shoulder, flank and thigh was irregular.
