| Abstract | This aim of this study was to estimate the most reasonable slaughter month for Hanwoo steers according to carcass traits. Carcass trait data on Hanwoo steers (17,249 head) were collected from October 2008 to September 2011. To measure the regression coefficients, Hanwoo steers were divided into two groups according to slaughter age: early (25 to 31 months) and late (32 to 38 months) groups. Regression coefficients of carcass traits according to slaughter age were significantly different (p<0.001) with the exception of PPKG (estimated auction price per 1 kg of carcass weight) in the early slaughter age group and MAR (marbling score, p<0.05) and PPKG (p<0.05) in the late slaughter age group. To obtain a positive gross margin, Hanwoo should be slaughtered at around 28 months of age. 본 연구는 도체월령별 도체형질의 변화를 분석하여 적정 도축시기를 결정하는 데 필요한 정보를 얻기 위한 목적으로 실시하였으며, 2005년 10월부터 2011년 9월 사이에 도축된 거세우 17,249두의 도체형질자료를 이용하였다. 각 도체형질의 평균과 표준편차는 도축일령, 도체중, 등지방두께, 등심면적, 근내지방도, 육량지수, 도체단가 및 도체 총가격에서 각각 $940.4{\pm}73.00$, $437.0{\pm}48.70$ kg, $12.1{\pm}4.32$ mm, $90.3{\pm}9.51cm^2$, $5.7{\pm}1.86$, $65.13{\pm}3.23$, $14.150{\pm}1.77$천원 및 $6181.18{\pm}1009.46$천 원으로 나타났다. 도체월령별 회귀계수에서 조기 도축그룹에서는 도체 단가를 제외한 전체 형질들에서, 만기 도축그룹에서는 근내지방도를 제외한 전체 형질들에서 월령별 회귀계수가 유의성이 인정되었다. 수익을 얻기 위해서는 28개월령 이전으로 도축시기를 결정해야 할 것으로 판단된다. |
