Role of genes related to performance and reproduction of Thoroughbreds in training and breeding – A review

Abstract

Abstract Thoroughbreds have been selected for speed and stamina since the 1700s. This selection resulted in structural and functional system-wide adaptations that enhanced physiological characteristics for outstanding speed of 61–71 kph (38–44 mph) between 1,000 and 3,200 m (5 furlongs – 2 miles). At present, horseracing is still an economically important industrial sector, therefore intensive research is underway to explore genes that allow the utilisation of genetic abilities and are significant in breeding and training. This study aims to provide an overview of genetic research and its applicability related to Thoroughbreds.
