摘要:

试验旨在对新疆褐牛体尺指标进行分析,研究其生长发育规律并揭示各性状间的相互关系。选取2010~2015年间伊犁昭苏地区8~20月龄新疆褐牛公牛,共计2 794头,测定其体重、体高、体斜长、胸围及管围指标数据,绘制生长发育曲线,并对新疆褐牛2010~2015年体尺测定数据进行相关性回归分析及验证。结果表明,新疆褐牛公牛的体长在14~15月龄间增长较快;体重与所测4项体尺指标间均呈正相关关系,且均为极显著(P<0.01),其中与胸围相关性系数最高(r=0.796),与体长的相关性系数最低(r=0.163);获得新疆褐牛公牛体重回归预测方程:Y=-564.607-0.174X1+2.441X2+3.497X3-1.086X4,经过验证回归方程具有统计学意义,为新疆褐牛的选育提供数据基础。

Abstract:

The experiment was designed to investigate growth and development pattern and reveal the correlation of each traits of Xinjiang Brown cattle according to analysis body index data.2 794 Xinjiang Brown bulls were selected to measure body index and draw the growth curve of body weight during year 2010 to 2015 in Yili Zhaosu region.The body index was composed by body weight,body height,body length,chest circumference and canon circumference.All measured data were analyzed and validated underwent correlation and regression analysis.The results showed that body length of Xinjiang Brown bulls were grow fastely at the age 14 to 15 months;Body weight was extremely significantly positive correlated with other four measured body index (P<0.01).Of them,the correlation coefficient with chest circumference was the highest (r=0.796),and the lowest was with body length (r=0.163).The body weight regression estimate formula of Xinjiang Brown bulls was Y=-564.607-0.174X1+2.441X2+3.497X3-1.086X4,and the validation result implied this formula was statistical significance.Our work offers a good data basic for genetics selection and breeding of Xinjiang Brown cattle.
