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%.

본 연구는 성, 도축계절 및 도축연도가 도체형질에 미치는 영향을 조사하고, 도체형질이 경락가격과 총가격에 미치는 기여도를 추정하기 위해 수행되었다. 2008년에서 2010년까지 도축된 한우4,231두의 도체등급 자료를 분석에 이용하였다. 성, 도축계절 및 도축연도는 도체형질에 유의적인 영향을 미쳤다. 준부분 상관제곱(squared semi-partial correlation) 값을 이용한 요인별 기여도 분석에서 경락가격의 R-Square는 0.55로 나타났다. 등지방두께, 배최장근단면적, 도체중 및 근내지방도의 경락가격 기여도는 각각 2.66, 0.32, 3.48 및 93.54%였다. 총가격의 R-Square가 0.82로 나타났으며, 근내지방도와 도체중의 기여도는 각각 46.25%와 52.38%였다.
