Abstract

|
This study was carried out to investigate the correlation of body measurement type and carcass traits. This study used body measurement type and carcass traits on 1,312 heads of Hanwoo steers tested(24 months) which was from 1997 to 2002 at Hanwoo Improvement Main Center National Agricultural Cooperatives Federation. Body measurement type used the age of 18 months body measurement type, and carcass traits used the results of decision grade of Animal Products Grading Service. Observing the phenotypic correlation between carcass traits and body measurement type from the result, the weight, withers height, and chest width at age of 18 months and carcass weight showed readings of 0.690, 0.483, and 0.506, respectively. Also, eye muscle area and age of 18 months weight and chest width read 0.356 and 0.279, respectively. According to results, that improvements in weight, withers height, and chest width are likely to enlarge the eye muscle area and meat production level. Not only quality improvement but also quantity augmentation affect income and sales of the farmers. As can be seen in this study, improvements of weight, withers height and chest width should always be put to much effort while other body measurement type should be considered continuously too. In order to attain clearer results further studies should be done on body measurement type, which will contribute to the improvements of body measurement type in Hanwoo.
