생체에서 초음파 측정기를 이용한 한우 도체형질의 추정에 관한 연구 = A Study on Estimation of Carcass Traits in Live Han woo by Using the Ultrasonic Scanning Method

다국어 초록 (Multilingual Abstract)

The carcass traits in live Hanwoo were estimated using the ultrasonic color scanning scope. A total number of 229 bull and steer records were measured. The data were collected for two years from 1992 to 1993. `Ihe estimates of backfat thickness using ultrasonic measurement from live animals for bulls and steers were 0.5㎝ and 0.91㎝, respectively, and those of slaughter measurement were 0.48㎝ and 0.91㎝, correspondingly. And also, the similar results were found for eye muscle area(EMA). The blue dot percentage indicating the marbling score tended to increase from 18 month of age to 21 month of age. The prediction equation using the linear regression were highly accurate for meat quantity(R²=0.91 to 0.93) but was less accurate for meat quality(R²=0.4).
