속보 운동시간이 제주교잡마의 혈액학 및 혈액화학치에 미치는 효과 = Effect of the Time of Trot on Hematology and Blood Chemistry in Jeju Pony Crossbreed Horses

국문 초록 (Abstract)

본 연구는 국내 승용마로 가장 많이 이용되는 제주교잡마(14.1±1.4세, 거세)의 운동시간이 혈액학과 혈액화학치에 미치는 영향을 평가하기 위하여 실시하였다. 속보 운동 시간에 따라 바이탈 사인과 스트레스 연관된 cortisol 및 lactic acid를 포함한 총 28가지 항목을 검사하였다. 바이탈 사인 중에서 심박수(평균 38.0→81.0회/분)와 호흡수(평균 11.7→35.7회/분)는 운동 전에 비하여 운동 30분에 유의하게 증가하였다(p<0.05). 그러나 체온은 운동 전후에 차이가 없었다. 혈액학 조사 결과 white blood cell(8.03→9.52×10³cells/μL), red blood cell(5.94×10³→7.23-7.32×10³cells/μL), hemoglobin(11.82→14.65-14.78g/dL) 및 hematocrit(25.04→30.27%) 수치는 운동 전에 비하여 운동 30분에 유의하게 증가하였다(p<0.05). 혈액화학치 조사 결과 알부민(3.25→3.47g/dL)만이 유의하게 증가하였다(p<0.05). 그러나, Na⁺, K⁺, Ca²⁺, total CO₂, creatine kinase, glucose, blood urea nitrogen, creatinine, aspartate transaminase, total bilirubin, gamma-glutamyl transpeptidase 및 total plasma protein 수준은 차이가 없었다. 한편 cortisol 및 lactic acid 수준도 운동 전과 운동 30분에 유의한 차이는 없었다. 이상의 결과를 종합하면, 제주 교잡마에서 30분간 속보 운동은 운동에 의한 스트레스를 받지 않으므로, 승마의 안전성과 동물복지 측면에서 문제가 없을 것으로 판단된다.

다국어 초록 (Multilingual Abstract)

This study analyzed the effect of time of trot on hematology and blood chemistry values of the Jeju Pony crossbreed horses that are commonly used for riding (14.1±1.4 years old, Gelding). A total of 28 parameters including vital signs as well as stress hormones such as cortisol and lactic acid levels were examined as the time of the trot exercise progressed. Vital signs such as heart rate (38.0→81.0 times/min) and respiratory rate (11.7→35.7 times/min) increased significantly within 30 minutes of exercise. However, difference in the body temperature was not observed before and after exercise. The hematology including white blood cell count (8.03→9.52×10³ cells/μL), red blood cell count (5.94×10³→7.23-7.32×10³ cells/μL), hemoglobin levels (11.82→14.65-14.78 g/dL), and hematocrit levels (25.04→30.27%) significantly increased 30 minutes after the start of the exercise (p<0.05). The blood chemistry value of albumin (3.25→3.47 g/dL) (p<0.05) only showed a significant increase after the exercise. However, the other blood chemistry levels such as, Na⁺, K⁺, Ca²⁺, total CO₂, creatine kinase, glucose, blood urea nitrogen, creatinine, aspartate transaminase, total bilirubin, gamma-glutamyl transpeptidase, and total plasma protein did not change. Also, cortisol and lactic acid levels did not show significant difference. The middle-aged Jeju pony crossbreed horses were not stressed by the 30-minute exercise; therefore, it can be concluded that there is no problem regarding the safety of both the rider and the animal.
