Abstract

The health status of three groups of Hanwoo steers (n=157) aged 2-3 years, raised at three different altitudes (600 m, n=50; 200-400 m, n=58; plane land, n=49) and environment with more or less similar management have been evaluated through hematological, biochemical and globulin examinations in order to determine the optimum environment suitable for raising cattle while at the same time minimizing the risk of disease. Five mL of blood samples from each animal were collected by jugular veinipuncture and 2 mL was transferred to a tube containing EDTA for complete blood count (CBC) and 3 mL in lithium heparin for chemistry screening (CS) and immunoassay. Among the CBC parameters a significantly higher white blood cell count (tWBC), total red blood cell count (tRBC), hemoglobin (Hb) and packed cell volume (PCV) were noticed in the high altitude groups, whereas those were lower in the plane land group. In the CS parameters higher levels of aspartate aminotransferase (AST), creatinine, lactate dehydrogenase (LDH) and total bilirubin (TBL) were found in the plane land group, whereas those were lower in the high altitude groups. The total protein (significantly) and globulins were higher in the 600 m group. The results of this study revealed that the overall health status of the Hanwoo cattle based on the hemato-biochemical indices was superior in the highest altitude and inferior in the plane land group but all the parameters were within the reference range in all the groups. Therefore, for recommendation of a suitable environment at an appropriate altitude for raising cattle there need to be further studied along with the hemato-biochemical parameters; considering, breeding, feeding, management, marketing, waste disposal and other factors.

서로 다른 고도에서 사육하고 있는 2-3세령의 수컷, 건강한 비육 한우를 세 그룹(600 m, n=50; 200-400 m, n=58; 0 m n=49)으로 나누어 혈액 및 혈청검사 그리고 면역항체가 검사를 실시 하였다. 고도를 제외한 일반 사육 환경과 식이 및 축사의 형태는 매우 비슷한 조건이였으며 질병이 확인 된 개체는 통계에서 제외 하였다. 경정맥에서 채취한 혈액은 일반혈액검사 중 WBC, RBC, Hb, PCV 를, 혈청화학검사 중 AST, LDH, TBL를 집중적으로 비교 분석하였으며 또한 면역학적 검사를 실시하였다. 고도가 높은 그룹이 낮은 그룹에 비하여 CBC에서는 조금 높게 나타났으며, 혈청검사에서는 평지에서 사육된 한우가 조금 높게 나왔다. 그러나 모두가 정상범위를 벗어나거나 통계적으로 유의한 수준의 차이를 보이지 않았다. 이러한 결과는 지금까지 알려진 대부분의 연구결과와는 차이가 있는 것이다. 본 연구와 지금까지의 알려진 연구와의 이러한 차이는 과거의 연구들은 고도의 차이가 현저한 경우가 대부분이었으나 본 연구에서 조사한 지역은 서로 고도가 비슷한 점에서 생긴 결과라고 여겨지며, 특히 고도가 600m 이하인 지형에서는 서로 큰 영향을 받지 않는 것으로 생각된다. 따라서 한우의 경우 목장 시설의 건축시 지형에 따른 어려움과 주변에서 들여오는 조사료의 수송에 따른 경제적 불리, 축산폐수 처리는 물론 퇴비의 활용 등 전반적인 목장 관리 면에서 고도가 높은 산지 보다는 평지가 권장된다.
