不同月份成年阿勒泰羊黑色毛绒品质变化规律研究OACSTPCD

To further understand the variation patterns of black coarse and fine wool characteristics of Altay sheep in different months,wool samples from 100 adult Altay ewes collected from November 2020 to April 2021 were analyzed to investigate the correlations among various traits.The results showed that(1)the wool content increased first and then leveled off with the progression of months,with January be-ing the peak month for wool content in adult Altay ewes(50.32％);(2)the average fiber diameter de-creased and then increased with the progression of months,reaching the minimum in February(21.63 pm);(3)staple length decreased first and then increased with the progression of months,with November having the highest average staple length(43.55 mm);(4)the percentage of breaking extension decreased first and then leveled off with the progression of months,with the highest value in November(47.18％);(5)there were no significant differences(P＞0.05)in wool whiteness and glossiness between November-December,February,and April;(6)from November to April,wool content in January was significantly higher than in November,fiber diameter in February was significantly smaller than in November,comfort in February was significantly better than in December,and wool whiteness and glossiness in January were both superior to December.The experimental results indicate that January to February are the months when the Altay ewes carry supreme wool.
