This study was carried out to estimate the heritabilities for body weights and body measurements and to analysis the relation among body weight and body measurements of female Korea Native Beef Cattle(HANWOO) at birth, 3, 6, 12, 18, 24 and 32 months of age. The data used for this study consisted of 3051 heads of registered female cattle(HANWOO) which were collected in the 8 provinces from 1979 through 1985 by the KAIAand NLCF. When the cost and labor in the measurement of the body were considered, the effective stepwise regression model of the body measurements on the body weight by the maximum R² improvement was the Model 6 including chest girth, rump width, rump height, thuds width, withers height and body length. The determinent coefficient(R²) of the Model 6 was 0.91. The heritabilities of the body weights at birth, 3, 6, 12, 18, 24 and 32 months of age were 0.20, 0.50, 0.48, 0.47, 0.22, 0.89 and 0.77, respectively. The ranges of the heritabilities on body measurements of withers height, rump height, body length, chest depth, chest width, rump length, rump width, thuds width, chest girth, and shank circumference at birth through 32 months of age were 0.05-0.86, 0.41-1.32, 0.20-1.05, 0.28-0.84, 0.10-0.90, 0.18-0.92, 0.20-0.63, 0.12-0.85, 0.22-0.92 and 0.09-0.91, respectively.
