摘　　要：为了研究三河牛各体尺指标与体重之间的关系，试验应用SAS9．0和Excel2007软件分析2011--2015年出生的781头三河牛初生体尺、体重及二者的相关性。结果表明：三河牛体尺随着体重的增加逐渐增大，其中体斜长和腹围与体重的相关系数分别为0．99，0．98，三河牛的管围与体重、体斜长、体高、胸围和腹围之间的相关都达到了极显著水平（P〈0．01）。说明三河牛在60—69kg体重时，体尺迅速增长；三河牛体尺指数与体重存在密切相关性。To study the relationship between body size indexes and body weight of Sanhe cattle, SAS 9.0 and Excel 2007 softwares were applied to analyze the birth body size and body weight and the correlation between them in 781 Sanhe cattle born from 2011 to 2015. The results showed that each body size in Sanhe cattle gradually increased with the increase of weight, thereinto, the correlation coefficients of the body slope length and abdominal circumference with body weight were 0.99 and 0.98, respectively, and the correlations reached extremely significant levels （P 〈0.01 ） between the cannon bone circumference and body weight, body slope length, body height, chest circumference and abdominal circumference. The results indicate that the body size of Sanhe cattle quickly increases when the body weight was between 60 and 69 kg per cattle, and the body size indexes are closely correlated with body weight.
