Results and discussion Regression of body weight on different body measurements The increase with age in the BW, heart girth, wither height and body length of the heifers in experiment I is presented in Figure 1. Correla- tions between BW and body measurements were high (r > 0.93).	cache/afs-72727.pdf	txt/afs-72727.txt
