摘　　要：利用EXCEL函数中的IF函数实现对荷斯坦牛20个体型线性性状(包括体高、胸宽、体深、腰强度、尻角度、尻宽、蹄角度、蹄踵深度、骨质地、后肢侧视、后肢后视、乳房深度、中央悬韧带、前乳房附着、前乳头位置、前乳头长度、后乳房附着高度、后乳房附着宽度、后乳头位置和棱角性)鉴定原始数据快速、简便地转化为对应功能分。根据各性状权重,计算个体体躯容量、尻部、肢蹄、泌乳系统和乳用特征5个部位得分以及个体总分。利用荷斯坦牛体型性状功能分,对牛场牛只选种选配提供技术支持。IF function of EXCEL function was used to realize the rapid transformation of the original data of 20 linear type traits in Holstein cows.20 body shape linear traits were body height,chest width,body depth,waist strength,rump angle,rump width,foot angle,heel depth,bone structure,rear legs set,rear legs rear view,udder depth,central ligament,fore udder attachment,front teat placement,front teat length,rear udder height,rear udder width,rear teat placement,and angularity.According to the weight of each trait,the scores of five parts including truncus capacity,rump,feet and leg composite,udder composite,dairy form and the total scores of individuals were calculated.The function scores of type traits in Holstein cattle were used to provide technical support for cattle breeding.
