Transporting Mares and Foals
Thanks to artificial insemination, it is not always necessary to transport a mare and foal to the stallion’s resident farm for breeding. Instead, semen is shipped to the mare’s owner for use at home. However, if the mare involved is a Thoroughbred, that is not an option since only live cover is allowed by the breed registry. There are also instances where a stallion’s semen doesn’t tolerate the shipping process. For some reason, the semen deteriorates rapidly when cooled, placed in a container, and sent across the country. In still other instances, the owner of a popular stallion simply might not want to go through the effort of collecting and sending semen. If you want to breed to him, you must send the mare. It is as simple as that.
Regarding the effects of transportation on foals, we generally have to start with research on adult horses. The University of California, Davis (UC Davis), reported on some extensive studies conducted by the team of Carolyn Stull, MS, PhD, from the UC Davis Center for Equine Health; and Ann Rodiek, MS, PhD, from California State University in Fresno. They studied the physiology of horses both during transport and during recovery. The study was conducted using a commercial equine van that traveled the interstate highways of central California under typical summer conditions.
The horses studied included 15 mature, healthy animals which were experienced travelers. Their physiological responses were documented during 24 hours of road transport, followed by a 24-hour recovery period during which horses rested in individual stalls. The findings of that study were reported in the October 2003 issue of The Horse Report (online at www.vetmed.ucdavis.edu/ceh/hreport.html), a publication detailing research findings at the University of California,
