摘要
本文对１９９０－１９９１年度双桥农场３个奶牛场６０３头荷斯坦奶牛体型线性性状评分与其成年奶当量进行了相关通径分析，数据采用ｄＢＡＳＥⅢ进行管理，应用Ｔｕｒｏ－Ｂａｓｉｃ编程在ＡＳＴ－２８６进行计算分析。分析表明：奶牛体型线性性状中，乳房深与成年奶当量呈较强负相关（ｒ＝－０．４２６６）；尻宽与产奶量呈正相关（ｒ＝０．２９３９）；这二者是影响成年奶当量的主要性状。
The paper analyses the somatotype liner properties and adults milk equivalent weight of 603 Holsten cows in shuangqiao farm during the year 1990-1991.the data was dealt with dBASEⅢ and using Turo-Basic programme under AST-286. The results show that adult cows manmary depth is in inverse proportion to milk equivalent (r=-0.4266),the width of hinderquarters is in direct proportion to high milk weight (r=0.2939),and these two items are the main factors affecting milk equivalent weight
