Comparative Analysis of Average Fiber Diameters of Different Breeds of Fine Wool Sheep in Inner Mongolia
摘要
Abstract
[Objective]In order to analyze the wool quality of different breeds of fine wool sheep in Inner Mongolia Autonomous Region,so as to provide some reference for breed selection and improvement.[Methods]In this study,9 local fine wool sheep breeds and 1 introduced Australian Merino sheep breed were selected,a total of 795 sheep were included.The one-way ANOVA was used to conduct a comparative analysis of indexes such as net wool rate,average fiber diameter,standard deviation and coefficient of variation of different breeds of adult rams and ewes by collecting wool samples from the lateral sides of the sheep.At the same time,combined with census data of the livestock and poultry genetic resources in 2006 and the supervision and testing data of breeding livestock and poultry in 2018,the changes of the average fiber diameter and net wool rate of fine wool sheep in Inner Mongolia were compared between different years.[Results]The results showed that:The influence of different breeds on the net wool rate varied significantly(P<0.05),and the net wool rate of the samples ranged from 54.62%to 62.86%;The influence of different breeds on the average fiber diameter,standard deviation and coefficient of variation varied significantly(P<0.05),and the average fiber diameter of Australian Merino sheep was significantly lower than that of other breeds,with the thinnest average fiber diameter of adult ewes being 19.46 µm,the cultivated breed,Chinese Merino sheep(Horqin type),came second,with the diameter of adult ewes being 20.18 µm,the fiber diameters of other breeds were relatively thicker,all exceeding the fineness of 21.5 µm required by the market;Compared with the changes of average fiber diameters in 2006,2018 and 2022,the average fiber diameter of the cultivated breeds of Inner Mongolia fine wool sheep showed a trend of thickening.[Conclusion]There were still significant differences between the cultivated breeds of fine wool sheep in Inner Mongolia and the international superfine wool sheep.It was necessary to pay attention to the changes of wool fineness and accelerate the intensity of breed selection to enhance its value in textile processing.关键词
