The purpose of this paper is to investigate the performances of the body weights and the 11 body measurements of Hanwoo raised between 1987 and 1989 in farms and Hanwoo progeny test center. The body weights at birth, 6, 12, 18 and 24 months of age were 22.49kg, 148.18kg, 223.48kg, 267.76kg, and 291.77kg respectively. The body measurements were increased rapidly up to about 6 months of along with the body weight. Feeding managements and the nursing capacity of dam were considered important. factors to develop the body size of a calf early growing stage. As compared with the previous reports, for the body weights at 6 and 12 months of age and the measurements for body length, chest girth, and shank circumference at 6, 12 and 18 months of age were somewhat increased. This might be come from the improved feeding managements and the change of growth type by selection. The hipbones width(pinbones width), which had not been reported, at birth, 6, 12, 18 and 24 months of age were 8.96cm, 19.09cm, 19.26cm, 21.04cm, and 22.19cm respectively. The body measurements of 11 traits of male calves at 7 months of age shown to be similar to those of female calves at 12 months of age.
