Abstract

This study was conducted to estimate genetic parameters for ultrasound and carcass traits in Hanwoo. Heritabilities and genetic and phenotypic correlations were estimated for carcass and ultrasound measurements collected from Hanwoo cows (n=312) born at Hanwoo experiment station. Traits evaluated were eye muscle area (EMA), backfat thickness (BF), marbling score (MS) from carcass, and ultrasound eye muscle area (UEMA), ultrasound backfat (UBF), and ultrasound marbling score (UMS). Parameters were estimated using multi-trait animal models byderivative-free restricted maximum likelihood procedures. Estimated heritabilities for UBF, UEMA and UMS were 0.43, 0.23 and 0.32, while heritabilities for BF, EMA and MS were 0.33, 0.13 and 0.33 in fattened cows, respectively. Genetic correlations between ultrasound and carcass measurements were estimated to -0.19, -0.61, and -0.36 for UBF: UEMA, UBF: UMS, and UEMA: UMS in fattened cows, respectively. Phenotypic correlations between ultrasound and carcass measurements were 0.03, 0.13 and 0.26 for UBF: UEMA, UBF: UMS, and UEMA: UMS in fattened cows, respectively. As for the steer, genetic correlations between ultrasound and carcass measurements were 0.36, -0.80 and 0.27 for UBF: UEMA, UBF: UMS, and UEMA: UMS in steers, respectively. Phenotypic correlations between ultrasound and carcass measurements were 0.13, 0.07 and 0.41 for UBF: UEMA, UBF: UMS, and UEMA: UMS in steers, respectively. In conclusion, this finding would be very useful to implement into Hanwoo breeding program.

본 연구는 한우 번식우와 거세우의 도체형질과 초음파 측정형질의 유전모수를 추정하여 도체형질과 초음파 측정형질 간의 관계를 알아보기 위하여 실시하였다. 한우 암소에 있어서 초음파 등지방두께의 유전력은 0.43이었고, 초음파 등심단면적의 유전력은 0.23 그리고 초음파 근내지방도는 0.32이었다. 한편, 한우 암소 도체형질의 유전력은 등지방두께는 0.33, 등심단면적이 0.13 그리고 근내지방도는 0.33으로 분석되었다. 한우 암소에 있어서 초음파 측정 형질 간 유전상관은 초음파 등지방두께: 초음파 등심단면적에서 -0.19, 초음파 등지방두께: 초음파 근내지방도는 -0.61이었고, 초음파 등심단면적: 초음파 근내지방도는 -0.36으로 각 형질 간 부의 유전상관을 보였다. 표현형상관에 있어서는 초음파 등지방두께: 초음파 등심단면적에서 0.03, 초음파 등지방두께: 초음파 근내지방도는 0.13이었고, 초음파 등심단면적: 초음파 근내지방도는 0.26으로 분석되었다. 한우 암소에 있어서 초음파 측정 형질과 실제 도체형질 간 유전상관은 등지방두께 0.97, 등심단면적 0.94 그리고 근내지방도 0.92로 매우 높은 정 (+)의 상관을 나타내었고, 초음파 측정형질과 실제도체형질 간 표현형상관에 있어서도 등지방두께 0.90, 등심단면적 0.86 그리고 근내지방도 0.81로 높은 정 (+)의 상관계수가 추정되었다. 그리고 암소에서 나타나는 이러한 결과는 거세우 자료에서나 암소와 거세우를 통합한 자료에서도 일관되게 나타나고 있다. 본 연구에서 초음파 측정치와 실제 도체에서 측정한 값 들 사이에 유전적으로나 표현형적으로 높은 수준의 정 (+) 상관이 존재하는 본 연구 결과는 육질 개량을 위한 간접 선발의 도구로 초음파 측정 자료를 활용하는 것이 가능할 것이며 한우의 도축 결과를 상당히 정확한 수준으로 예측하는 것이 가능하므로 사양관리 측면에서도 큰 활용 가치가 있을 것으로 판단한다.
