There are several questions requiring attention for rearing horses. By providing appropriate care during early ages, important injuries such as lameness or musculoskeletal damage can be avoided, which becomes of capital importance especially among competition horses. In recent years, there has been an increasing body of evidence that the early rearing environment, in particular access to exercise, can have a positive effect on stimulating the musculoskeletal system and priming the tissue for the future demands it will face in the competition arena. Due to different reasons, such as their participation in competitions or exhibition, sales or pleasure, horses are transported from one location to another. Transportation could be a physical and psychological stressor for horses, contributing to the development of some diseases, thus the effects of transportation on performance and welfare should be appropriately taken into account.
