Analysis of Wool Quality of Adult Female Altay Sheep at Different Ages
摘要
Abstract
In order to study the differences in phenotypic traits of Altay wool quality among different age groups and provide reference data for the breeding of Altay sheep,a total of 439 Altay ewes aged 1.5 to 5 years were sampled for wool analysis.The results showed that age significantly influenced the fiber diam-eter and staple length of Altay wool(P＜0.01),and had a significant effect on fiber strength(P＜0.05).Ewes at 1.5 years old had the finest fiber diameter,while those at 2 years old had the highest staple length.Ewes at 5 years old had significantly higher fiber diameter and staple length compared to other age groups(P＜0.01),and ewes at 1.5 years old had significantly higher fiber strength compared to other ages(P＜0.01).The fiber diameter of Altay wool was highly positively correlated with staple length and fiber strength(P＜0.01).The fiber content was highly positively correlated with coarse wool whiteness,coarse wool luster,and elongation at break(P＜0.01),and wool whiteness was highly positively correlated with wool luster(R=0.998),coarse wool whiteness,and coarse wool luster(P＜0.01).These research find-ings provide a reliable basis for the evaluation of Altay wool quality and the breeding of superior livestock.关键词
