Understanding Reproductive Physiology and Anatomy of the Mare

A working knowledge of the mare’s reproductive anatomy and physiology is essential in a horse breeding program. This knowledge provides the fundamental basis on which all other principles of horse breeding rest. The following article discusses the reproductive anatomy of the mare and explains the importance of each part.

Weaning and Management of Weanling Horses

Management of weanlings and the weaning process can be complex and challenging. This article provides recommendations on preparing the foal to be weaned, weaning methods and care and management of the weanling horse.
Young, weaned horses below the age of 1 year are called weanlings. During this time of life, the foals have been separated from their dams, are rapidly growing and are receiving training and management practices that have life-long effects. This fact sheet provides recommendations on preparing the

Broodmares and Fescue Pasture

Broodmares that graze endophyte-infected fescue pasture have potential foaling, lactation and re-breeding problems. The following article discusses the potential problems that may occur if a broodmare is allowed to graze on endophyte-infected fescue.
Now that spring is here, foals are arriving. Spring and early summer is nature’s time for most foals to be born. In the Southeast and other areas of the United States, many pregnant mares graze tall fescue pastures. Unfortunately, many of these fescue pastures are infected with

Developing a Horse Breeding Program

The goal of every horse breeder is to produce genetically superior horses. Because there are so many environmental conditions which affect the horse, it is difficult to evaluate the genetic potential. A gifted breeder is able to select superior horses for mating, and manages the environmental affects, such as nutrition, health care, training and injuries, to maximize the horse’s genetic potential. Since breeding for quality horses is not a simple matter, breeders must understand basic genetic principles and their application …
