Horses play a unique role in human activities, for both work and recreation. From the ranch to the racetrack, an understanding of horses' behaviour and needs is vital for man to ensure their well-being. Providing a comprehensive, scientific overview of horse behaviour and its relation to welfare, this new, updated edition includes new developments in the understanding of the relationship between physiology and performance, and the neuro-chemical basis of stereotypic behaviour. It has been expanded to address the important topic of welfare from both a fundamental and a practical viewpoint, and will serve as an essential resource for veterinarians, equine professionals and horse owners as well as students of veterinary and animal sciences.
