Abstract:
【Objective】 The research was conducted to investigate the influence of non-genetic factors on the cashmere characters of Liaoning cashmere goats.【Method】 Firstly,the wool yield and body weight of 144 experimental Liaoning cashmere goats were measured. Then,the average fiber curvature,average fiber diameter,standard deviation of fiber diameter,average fiber length,coarse hair number and coefficient of variation of fiber diameter of cashmere were measured. Finally,the effects of gender,age and growth site on these traits were analyzed.【Result】 The results showed that cashmere yield,body weight after combing,mean fiber diameter,coarse edge micron,mean staple length and fiber diameter standard deviation of Liaoning cashmere goat rams were 366. 31 g,15. 98 kg,1. 59 μm,0. 83,5. 16 mm and 0. 43μm higher than those of Liaoning cashmere goat ewes,respectively. The cashmere yield,body weight after combing,mean fiber diameter,coarse edge micron,fiber diameter standard deviation and coefficient of variation of fiber diameter of four-year-old Liaoning cashmere goats were 810. 65 g,51. 45 kg,16. 26 μm,1. 96,3. 62 μm and 22. 16%,respectively,and these cashmere traits were significantly higher than those of one-year-old,twoyear-old and three-year-old Liaoning cashmere goats(P<0. 01). The mean fiber curvature of one-year-old Liaoning cashmere goats was 84. 52
o/mm,which was significantly greater than those of two-year-old,three-year-old and four-year-old Liaoning cashmere goats(P<0. 01). The mean fiber diameter(15. 52 μm)and mean staple length(51. 58 mm) of scapular cashmere were the largest. The mean fiber diameter of scapular cashmere was 0. 04 μm and 0. 12 μm higher than those of thigh cashmere and ventral cashmere,and its mean staple length was 1. 68 mm and 0. 98 mm longer than those of thigh cashmere and ventral cashmere,respectively. The standard deviation(3. 13 μm) and coefficient of variation(20. 28%) of ventral cashmere were the smallest among the three parts studied.【Conclusion】 It was suggest that sex and age significantly affected some of the cashmere characters,and that cashmere fiber quality was different among different fur parts of Liaoning cashmere goats.
