Abstract

The present study investigated the effect of average daily gain (ADG) on carcass traits of Hanwoo steers. A total of 233 heads of Hanwoo steer slaughtered from 2017 to 2020 were employed in the analysis. Their body weight profiles during feedlot and carcass traits were used. The entire feedlot period is split into two periods. ADG during the first period (ADG1) was then defined as an independent variable in statistical analysis. In the meantime, it was examined that how the cutoff month for the period split altered the significance of the effect of ADG1 on carcass traits. Subsequently, steers were assigned to two groups (High vs. Low) based on the median of total ADG1, and we compared the carcass traits of each group using a linear mixed model. ADG1 during 10 to 23 months showed a significant effect on all carcass traits except the marbling score. ADG1 significantly influenced carcass weight and eye muscle area of Hanwoo steers. And it was found that greater ADG1 could get greater carcass weight and eye muscle area (p<0.001). The result of this study provides preliminary information for the target month in the calculation of ADG1 mostly influencing carcass performance, and feeding strategy of Hanwoo steer in terms of sustainability.

일련의 분석결과 10~23개월령 한우 거세우의 일당 증체량이 도체 성적에 미치는 영향이 크다는 것을 알 수 있었다. 본 연구 결과는 한우 생산성 향상과 영양 및 사양관리 전략 수립에 기초 자료로 활용될 수 있을 것이다.
