ABSTRACT
The study involved over 1400 mohair sale lots, representative of two different growing seasons Winter and Summer for each of the two different years (2010 and 2015). The results of the two years (2010 and 2015) were generally in good agreement and could, for all practical purposes, be treated as one population. It was found that, as expected and is well known, the number of objectionable medullated fibers (kemp type) were highest in the Kid mohair produced in the first shearing (i.e. approximately 6 months after birth). Furthermore, the total number of flat and objectionable medullated fibers was related to the mean fiber diameter and the width of the fiber diameter distribution (CVD) of the sample but could not be predicted accurately from the latter values. The effect of goat age on the various types of medullated fibers could generally be explained in terms of associated changes in mean fiber diameter and diameter distribution.
摘要
该研究涉及1400多个马海毛销售地块，代表了两个不同年份（2010年和2015年）的冬季和夏季两个不同的生长季节. 两年（2010年和2015年）的结果基本一致，从所有实际目的来看，可以将其视为一个群体. 研究发现，正如预期和众所周知的，在第一次剪切（即出生后约6个月）中产生的马海毛中，不良有髓纤维（kemp型）的数量最高. 此外，扁平和不良髓化纤维的总数与样品的平均纤维直径和纤维直径分布（CVD）的宽度有关，但不能从后一个值准确预测. 山羊年龄对不同类型有髓纤维的影响通常可以用平均纤维直径和直径分布的相关变化来解释
