摘要
为了解新疆褐牛生长发育规律,利用1~16月龄新疆褐牛公牛(1 059头)和母牛(1 276头)的体尺与体重测定数据绘制了生长发育曲线,并应用SPSS 16.0软件分析了各项体尺指标(十字部高、体斜长、胸围、管围)与体重的相关性。结果表明:新疆褐牛犊牛期各项体尺指标的生长速度低于育成期,犊牛期体重的生长强度大于育成期,生长速度小于育成期,整个生长期内各项体尺指标均与体重存在极显著(P<0.01)的相关性。
To explore the growth and development patterns of Xinjiang Brown Cattle bulls and cows,body weight and body size data from1059 bulls and 1279 cows at 1~16 months of age were used for the growth curves.Correlation analysis of the body weight and body size（body height,body length,chest circumference,pipe circumference） was made by SPSS 16.0.The results showed that the growth speed were lower,however,the growth strength of the body weights was bigger in the Xinjiang Brown Cattle during the calves period compared with growth period.Body measurements and body weights were highly correlated（P〈0.01） during the growth period.
