Abstract

Concentration of hormones and blood components at the last fatting stage was changed before slaughter in Hanwoo steers and bulls. Two months before slaughter and shipment, concentration of cortisol and creatinine was increased, but that of calcium was decreased. Concentration of insulin growth factor-1 (IGF-1) was decreased after shipment, and inorganic phosphorus (IP) was decreased at slaughter. It is unclear that changes of concentration in between 2 months before slaughter and shipment were either caused by aging or stresses (abstinence, environmental change, blood drawing, and shipment). Changes of blood concentration between shipment and slaughter may be accounted for overall responses from abstinence, shipment, and unfamiliar environment. A positive correlation between 2 months before slaughter and before shipment was detected for IGF-1, total protein (TP), albumin, creatinine, high density lipoprotein cholesterol (HDLC), and globulin in steers, and creatinine and globulin in bulls. A positive correlation between 2 month before slaughter and slaughter was detected for IGF-1, blood urea nitrogen (BUN), IP and HDLC in steers, and creatinine in bulls. A positive correlation between before shipment and slaughter was detected for testosterone, IGF-1, creatinine, triglyceride, HDLC and globulin in steers, and TP, creatinine, HDLC and globulin in bulls.

한우에서 도축 전 혈청 호르몬 및 혈액 성분의 농도 변화가 거세우와 비거세우에서 공통적으로 나타난 현상은 도축 2개월 전에서 수송 직전 사이에 cortisol과 creatinine이 증가하였고 calcium은 감소하였다. 수송 직전에 비해 수송 직후에는 IGF-1 농도가 감소하였으나 수송 직전에 비해 도축 시에는 IP농도가 감소했다. 혈청 호르몬 및 대사 물질들에서 도축 2개월 전, 수송 직전, 수송 직후 및 도축시 혈청들 간의 상관 관계는 도축 2개월 전 농도와 수송 직전 농도간에 정의 상관 관계를 보인 혈청은 거세우에서는 IGF-1, TP, albumin, creatinine, HDLC 및 globulin이며 비거세우에서는 creatinine과 globulin이었고, 도축 2개월 전 혈청과 도축시 혈청 간에 정의 상관관계를 보인 혈청 성분은 거세우에서는 IGF-1, BUN, IP 및 HDLC이었고, 비거세우에서는 creatinine이었다. 그리고 수송 직전 혈청과 도축시 혈청 간에 정의 상관 관계가 있는 혈청 성분은 거세우에서는 testosterone, IGF-1, creatinine, triglyceride, HDLC 및 globulin이었고, 비거세우에서는 TP, creatinine, HDLC 및 globulin으로 나타났다.
