*An Introduction To The Horse Reproduction System And Diseases

The mating of a stallion and mare should be easy, right? It can be if you learn 1 secret – the necessity of observing the horses and recording these observations accurately.  Accurate records reveal subtle patterns in mating behavior that can help in getting the mare to accept the stallion.  

There are 2 types of breeding: natural and artificial.  I have a series of images of my elder statesman gelding who was castrated late in life and continued to show good natural mating behavior, especially when turned out with his new girlfriend.  This is called pasture breeding and it is the way nature intended it to occur.  In breeding operations where only natural breeding is allowed yet a maximum return on effort is required for business, the stallion and mare are held by handlers trained in this very specific type of horsemanship.  I will discuss this as my training before vet school was on a Thoroughbred farm where hand breeding was the only way allowed.

Artificial breeding details are beyond the scope of this website as the complexities are nuanced and detailed.  However artificial breeding includes: 1) collection of the stallion either on a mare or a dummy mount, 2) the artificial insemination of the mare by a veterinarian, 3) the freezing or cooling of semen for shipment to other farms far away, 4) the collection of fertilized eggs and transfer of these ovums into recipient mares.  

Complicating things include shy or aggressive mating behavior, venereal diseases, systemic viral diseases, acquired reproductive tract infections, attrition or damaged sperm and eggs, twin fetus development, birth canal damage and abortion (pre-term and full term).  I’ll do what I can to touch on these topics but this subject could be a whole website.  In my 12 years of full vet practice I have seen all of these topics and I will have several stories to illustrate them all.

Anhidrosis (Non-sweating horses)

No one has determined why some horses in the same environment stop sweating while others do sweat but we know that every horse is different with different responses to triggers. And no one (to my knowledge) has determined the mechanism behind anhydrosis.
Accidentally we have found a cure that seems to work in every horse we try it with and we need your help to give us more examples of this treatment’s success.

Dental Care

Horse’s teeth erupt throughout their lives with constant wear occurring from teeth grinding against opposing teeth and continual stropping by the tongue. This wear is uneven and creates razor sharp edges that cause discomfort as those edges ulcerate the cheek and their tongue. So if eruption and wear is continuous throughout the life of the horse and the result is pain within the mouth, AND the removal of the sharp points (floating) is easily done, WHY DO SO MANY HORSE OWNERS AVOID THIS IMPORTANT ASPECT OF HORSEMANSHIP?
