초록

Recently, the horse racing industry in Korea has developed rapidly with good betting turnover. One of the most important factors in enhancing the performance of racehorses is the study of equine exercise physiology. This study was performed to analyze the results of pre-race blood test on race day and evaluate its correlation with the race performance in Thoroughbred racehorses. Twenty-one, healthy 3- to 6-year-old Thoroughbred horses were used to collect blood samples and hematological and biochemical measurements were performed. Results were analyzed to identify its correlation with racing performance. Analysis of hematological profile of pre-race blood of the racehorses revealed that red blood cell indices including RBC, Hb, and PCV levels were elevated. Additionally, levels of AP, AST, and GGT were also elevated in pre-race blood of horses on race day. RBC, Hb, and PCV levels of high performance racehorses were significantly lower than those of low class racehorses. Moreover, the analysis of correlation between blood test results and racing ability-related categories have shown negative correlations for rating, placing strike rate, prize money per race, RBC, Hb, and PCV and positive correlations for G3F and PCV. Additionally, AST value was positively correlated to prize money per race. Thus, the results of this study show that red blood cell indices and AST are good parameters for evaluating racing performance of horses before the race.
