摘要
为研究不同年龄阶段哈萨克羊生长发育规律,比较有角与无角哈萨克羊的生长规律和生产性能的差异,分别挑选1~5岁哈萨克羊2911只,其中无角哈萨克羊数量为1023只。对羊只的体重、体高、体斜长、管围、胸围、胸宽、胸深、尾宽、尾长等九个生长指标进行测量,并用SPSS 22.0软件分析。结果表明:2岁期间的体重、体高、胸宽、胸深等指标差异显著(P<0.05),3岁和2岁期间的体尺基本一致,4岁期间的体高差异显著(P<0.05),5岁期间的胸宽差异显著(P<0.05)。在1~2岁时无角与有角哈萨克羊的体重差异显著(P<0.05);无角与有角哈萨克羊1~5岁的体高、体斜长、管围基本一致;在1岁、2岁、3岁、5岁时无角与有角哈萨克羊的胸围差异显著(P<0.05),2岁、3岁、5岁无角与有角哈萨克羊的胸深差异显著(P<0.05)。结论为:哈萨克羊1~5岁期间的体重及体尺差异较小,生长速度较缓慢,无角与有角哈萨克羊各年龄阶段的其他体尺基本一致。
In order to explore the growth and development law of Kazak sheep at different ages,and compare the growth law and production performance of horned and hornless Kazakh sheep,637,726,681,624,and 243Kazakh sheep from 1 to 5 years old were selected respectively,of which the number of hornless Kazakh sheep were 241,213,255,207 and 107 respectively.The weight,height,oblique length,tube circumference,chest circumference,chest width,chest depth,tail width and tail length of sheep were measured and analyzed by SPSS 22.0 software.The results showed that there were significant differences in body weight,body height,chest width and chest depth during the 2 years old(P<0.05),the body size was basically the same between the 3 years old and the 2 years old period,the body height was significantly(P<0.05)different during the 4 years old,and the chest width was significantly(P<0.05)different during the 5 years old.There was a significant(P<0.05)difference in body weight between hornless and horned Kazak sheep at the age of 1to 2;The body height,oblique length and tube circumference of hornless and horned Kazak sheep aged from1 to 5 years are basically the same;There was significant difference in chest circumference between hornless and horned Kazakh sheep at the age of 1,2,3 and 5(P<0.05),and there was significant difference in chest depth between hornless and horned Kazakh sheep at the age of 2,3 and 5(P<0.05).The results showed that there was little difference in body weight and body size between 1 and 5 years old,and the growth rate was slow.The body size of hornless Kazak sheep was basically the same as that of horned Kazak sheep at all ages.
