本试验以新疆天山畜牧公牛站新疆褐牛、西门塔尔牛和荷斯坦牛的估测体重、体尺测定数据为基础材料，探索了三个品种的168头1~24月龄种公牛的生长规律，分析估测了体重与体尺指标的相关性。结果显示，不同品种种公牛随着月龄的增加，生长发育性状指标也相应增加，三个品种种公牛的估测体重与体高、体直长或体斜长的硬长与软长、胸围、腹围、睾丸周径、管围存在极显著正相关(P<0.01)。

This experiment studies 168 herds of bulls for different breeds which aging 1~24 month(s) from Xinjiang Tianshan Animal Husbandry Bio-engineering Co., Ltd bull station. The experiment regards estimated body weight, body ifgures as data material, exploring the growth and development rules of different varieties of bulls, analyzing the relevant correlation. Different varieties of bulls have various body traits as they are growing, our research shows that these three breeds of bulls differs magniifcently in estimated body weight and height, body length, chest diameter, abdominal width, testicular, cannon circumference, all the correlation was highly signiifcant(P<0.01).
