한우 거세우 예상유전전달능력(EPD) 형질의 보완성 검정

A Test for Complementarities among Expected Progeny Difference Traits of Hanwoo Steers

The purpose of this study is to analyze the complementarities among expected progeny difference(EPD) traits of Hanwoo steers. Data on 38,819 Hanwoo steers slaughtered from 2015 to 2016 were used. Four EPD traits are carcass weight(  ), eye-muscle area(  ), back-fat thickness(  ), and marbling score(  ). The results show that   and   always act as complements, except when   and   are used at the same time. when   is used,   and   are complementary. Additionally,   and   are complementary when   is used.   and   are complementary when   or   is used.   and   are complementary when   is used. However,   and   are subadditivity, when   and   are not used. The results also indicate that the revenues were higher in spring and lower in autumn and winter than in the summer. Furthermore, the carcass weight and rearing period were increased, the revenues were increasing. The results of this study may contribute to the government’s policy for Hanwoo breeding and provide useful information on Hanwoo rearing management.
