Abstract

Examination of correlation between blood compositions and economic traits is very important to improve selection accuracy and predict performance ability of Hanwoo, which may be impacted into the determination of feeding management as well as marketing places. This study was aimed to provide possible procedures of Hanwoo improvement as of early individual selection based on the phenotypic correlation between blood compositions and economic traits using 866 of Hanwoo managed at National Livestock Research Institute. Phenotypic correlation between blood compositions and economic traits was estimated for steer and bulls. BUN in steer and albumin and IGF-1 in bull were highly correlated with 24 mo of weight. Average daily gain of 21 to 24 mo was highly correlated with calcium in steer and albumin in bull. Back-fat thickness and marbling score were highly correlated with BUN in steer and bull, and meat yield index was highly correlated with calcium in steer and testosterone in bull. However, BUN, which is highly correlated with meat quality, was negatively correlated with meat yield index in steer and bull.

혈액성분과 경제형질들 간의 상관관계를 규명하는 일은 한우의 능력을 예측하고 예견되는 능력에 맞추어 사양관리와 판매처를 결정할 수 있고, 기존의 종축선발 체계와 결합시킴으로서 선발의 정확도를 향상시킬 수 있는 효과를 기대할 수 있으므로 나름대로 중요한 의미를 갖는다. 본 연구는 축산기술연구소에서 사육하고 있는 한우 866두의 혈액 중 호르몬과 대사물질을 분석하여 혈액성분과 경제형질과의 표현형 상관관계를 분석하고 혈액 내 유용한 생리적인 형질을 발굴하여 능력이 우수한 개체의 조기선발 가능성 구명과 선발 기술을 개발하여 한우개량에 또 다른 방법을 제시 하고자 실시하였다. 혈청성분들과 경제형질들 간의 표현형 상관계수를 거세우와 비거세우로 구분하여 추정한 결과 혈청성분들과 도체형질들 간의 주요 상관은 다음과 같다. 24개월 출하체중과 상관도가 높은 혈청은 거세우에서는 BUN이었고 비거세우에서는 albumin과 IGF-1이었으며, 비육말기 21∼24개월령의 일당증체량과 상관도가 높은 혈청은 거세우에서는 cal-cium이었고 비거세우에서는 albumin으로 증체와 관련 있는 혈청은 거세우에서는 calcium 비거세우에서는 albumin으로 나타났다. 육질과 관련 있는 등지방 두께 및 지방교잡도와 상관도가 가장 높은 혈청은 거세우와 비거세우 모두 BUN이었고, 육량등급의 근간이 되는 육량지수와 상관도가 높은 혈청은 거세우에서는 calcium이었으며 비거세우에서는 testosterone이었으나 육질과 상관이 높은 BUN은 거세우와 비거세우 모두가 육량지수와는 음의 상관을 나타내었다.
