THE EFFECT OF COAT COLOUR ON RACE PERFORMANCE IN THOROUGHBRED HORSES
 
Since the beginning of the domestication of the horse, they used; as food supply, for transportation, in battlefields, in agriculture and at trading. In modern days they have been used in hippotherapy, in scientific researches and they have been used as sport horses. Folk wisdom mention that Chestnut horses are better than the other horses and a few early studies reported that Chestnut horse had better race performance in long-distance than Bay horse. Recent studies indicate that race performance not affected by coat colour. A new publication which published in 2018 reports that potential regulatory regions near some genes may control both race performance and coat colour. Aim of this study was to investigate the effect of coat colour on race performance in Thoroughbred horse. The data of the last three race records of 95 Thoroughbred horses collected as the race performance. The effects of coat colour on race performance were analysed by using the t-test. The means of rankings and speed (m/s) were 6.8 and 15.5; 7.5 and 15.4; 7.8 and 15.3 for the 1st; the 2nd and the 3rd race for Bay Horses, respectively. And, the means of rankings and racing time were 6.4 and 15.4; 5.6 and 15.5; 6.7 and 15.1 for the 1st; the 2nd and the 3rd race for Chestnut Horses, respectively. Bay horses, were slower than Chestnut Horses. In conclusion, race performance was not affected by coat colour. Additionally, genetic studies should be conducted to understand the relationship between coat colour and race performance.
