摘要
【目的】研究新疆褐牛种公牛各体尺指标及估测体重之间的关系,掌握新疆褐牛种公牛的生长发育规律,明确选育方向,揭示性状间的相互关系,为开展新疆褐牛种公牛遗传育种、品种资源开发利用提供可靠的基础性数据资料。【方法】应用SPSS16.0软件分析新疆褐牛种公牛主要体尺指标及估测体重的相关性。【结果】新疆褐牛种公牛体尺指标及估测体重随着月龄的增加逐步增长,腹围和胸围增长速度高于其他指标。新疆褐牛种公牛体高﹑体长﹑胸围﹑腹围﹑管围和估测体重之间的相关系数均达到极显著水平(P<0.01)。【结论】新疆褐牛种公牛各体尺指标6月龄之前增长速度较快,随着月龄的增加逐渐趋于稳定。种公牛各体尺指标及估测体重间存在密切的相关性。
[ Objective]The relationship between body size and estimated weight of Xinjiang brown bulls were studied. The rule of the growth and development were analyzed. The direction of selection was definitized and the relationship among characters was revealed. The aim was to provide the histological basis for developing the heredity and breeding and the exploitation of breed resources. [ Method] The relationship between body size and estimated weight of Xinjiang brown bulls were analyzed with SPSS16.0. [ Result]The body size and estimated weight of Xinjiang brown bulls were progressively growing with aging. The growth rate of circum- ference and perimeter of abdomen were higher than that of the other indicators. The correlation coefficients between body height, body length and chest circumference, abdominal circumference, cannon circumference and estimated weight were all of significant difference （P 〈0.01 ）. [ Conclusion] The body size of Xinjiang brown bulls developed ,quickly before 6 months of age, and then it become stable with the aging. There was strong link between body size and estimated weight of Xinjiang brown bulls.
