Maintenance of fertility in the horse including artificial insemination.
A high fertility  rate depends on many different factors and is always related to inheritance and enviorment. The successful feritly control system in the German Thoroughbred breeding industry shows that fertility can be increased by good management and  veterinary supervision. The  insemination of horses with frozen semen is discussed. Replacement of natural service by A.I. with frozen semen is not generally  accepted in horsebreeding, as the conditions are entirely different from cattle breeding. However, there are several ways in which A.I. can be assistance in stud management.
