Analysis of wool trait differences in Zhongwei goats of different ages
摘要
Abstract
The experiment aimed to explore the effects of gender and age on the quality of cashmere and wool of Zhongwei goats under stall-feeding conditions.The experiment determined the average number of wool crimps in 35-day-old male and female lambs,the wool and cashmere length,average diameter,and diameter standard deviation in 1-and 2-year-old male sheep and 1-to 4-year-old female sheep,as well as the net wool rate and net cashmere rate in 1-to 4-year-old female sheep,and a comparative analysis of the above data was conducted.The results showed that the average number of wool crimps in 35-day-old male Zhongwei goats was 4.25,while that in female goats was 4.33.The average diameter of wool in 2-year-old female sheep was significantly larger than that in 1-year-old male and female sheep(P<0.05).There was no significant difference in wool diameter standard deviation among male and female sheep of different ages(P>0.05).The wool length in 1-and 2-year-old male sheep was significantly larger than that in 1-to 4-year-old female sheep(P<0.05),and the wool length in 3-and 4-year-old female sheep was larger than that in 1-and 2-year-old female sheep(P>0.05).The average diameter of cashmere in 1-year-old male sheep was significantly larger than that in 2-year-old male sheep and 1-,3-,and 4-year-old female sheep(P<0.05),and significantly smaller than that in 2-year-old female sheep(P<0.05).The average diameter of cashmere in 2-year-old male sheep was significantly smaller than that in 1-and 2-year-old female sheep(P<0.05),and the average diameter of cashmere in 2-year-old female sheep was significantly larger than that in 1-,3-,and 4-year-old female sheep(P<0.05).There was no significant difference in cashmere diameter standard deviation among male and female sheep of different ages(P>0.05).The cashmere length in 1-year-old male sheep was significantly larger than that in 2-year-old male sheep(P<0.05),and the wool length and cashmere length in 1-and 2-year-old male sheep were both larger than those in 1-to 4-year-old female sheep.There was no significant difference in the net cashmere rate and net wool rate among female sheep of different ages(P>0.05),and they showed a downward trend with the increase of age.The study showed that the average wool diameter,wool diameter standard deviation,and wool length of Zhongwei goats increased with age,and in the same age stage,the average wool diameter in male goats was smaller than that in female goats,while the cashmere length was larger than that in female goats.关键词
