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.
