초록

본 연구는 2004년~2008년에 미국에서 도입한 버크셔종의 육질 형질에 대한 유전적 특성을 파악하고, 향후 선발에 이용한 유전적 그룹(genetic group)을 분리하여 선발 및 교배계획을 체계적으로 세워 효과를 극대화시키는 전략을 세우고자 수행하였다. 그 결과 사후 대사율의 척도인 근육의 사후 45분 pH, 24시간 pH에 대한 유전력은 각각 0.60과 0.61로 높게 조사되었다. 육색의 척도인 명도, 적색도 및 황색도의 유전력은 0.56, 0.58 및 0.62로 조사되었다. 근내지방도, 유리육즙량과 가열감량에 대한 유전력은 각각 0.57, 0.51 및 0.66으로 조사되었다. 본 연구 결과로 미루어 볼 때 육질형질의 개량에 있어 육종가를 기초로 하여 선발에 활용할 경우 유전적 개량량은 크게 나타날 것으로 사료된다. 또한 사후 대사율의 척도인 pH와 육질형질과의 상관도는 높은 연관성이 존재하므로, 종돈장에서 육질형질을 개량하고자 한다면 육종가를 기반으로 한 선발지수(selection index)를 활용하면 매우 효과적일 것으로 필자는 사료된다. 그러나 본 연구에 활용된 자료는 유전모수를 추정하는데 다소 부족한 것은 사실이지만 국내 최초로 돼지의 육질형질에 대한 유전모수를 추정하는데 있어 매우 의미가 있다고 할 수 있다.

Swine industry in Korea plays an important role in providing the meat for domestic consumption, and the number of pigs in Korea was about 9.72 million heads as of June, 2010. Meat quality is used to describe any traits which impact the consumer acceptability of fresh meat products. Meat color, firmness, water holding capacity, ultimate muscle $pH_{24h}$ (measured 24 hours post-mortem), shear force, and intramuscular fat percentage (IMF) are generally accepted as important indicators of meat quality and ultimately, consumer acceptance of fresh pork. The objective of this study was to estimate genetic parameters for meat quality traits in Berkshire pigs. The heritability estimates for muscle $pH_{24h}$, lightness (CIE $L^*$), NPPC marbling were 0.61, 0.56 and 0.57, respectively, The heritability estimates for drip loss, cooking loss, shear force were 0.51, 0.66 and 0.56, respectively. The phenotypic correlations between $pH_{24h}$ and lightness (CIE $L^*$), drip loss, cooking loss were negative, ranging from -.45 ~ -.13. The genetic correlations between muscle $pH_{24h}$ and lightness (CIE $L^*$), drip loss were negative, ranging from -.35 ~ -.32. Genetic parameters obtained herein indicate that genetic improvement of muscle $pH_{24h}$ is not related to the NPPC marbling of meat, but rather to improved lightness(CIE $L^*$) and drip loss. Genetic trends of meat quality traits showed increased muscle $pH_{24h}$ and decreased cooking loss and drip loss.
