Abstract

The aim of this study was to estimate the effect of sex, slaughtered season and year on carcass traits, and the contribution of carcass traits to auction and total prices. The data used in this study were the carcass grade of Hanwoo (4,231 heads) slaughtered from 2008 to 2010. Carcass traits were affected significantly (p<0.01) by sex, slaughtered season and year. The R-Square of auction prices, analyzed the contribution of causes using the squared semi-partial correlation, was 0.55. The contributions of auction prices of backfat thickness, eye muscle area, carcass weight and marbling score were 2.66, 0.32, 3.48 and 93.54%, respectively. The R-Square of total price was 0.82, and the contributions of marbling score and carcass weight were 46.25% and 52.38%.
