Instructions
Find a suitable stallion for your mare and transport it to your stable.
Put the mare in a ring. The handler should let the stallion into the ring while keeping it under control. The stallion should not be allowed to run freely because it might harm the handlers and the mare.
Hold the mare's head with front reins to prevent it from running away.
Lead the stallion slowly toward the mare, approaching diagonally from the rear, and allow it to get only close enough to touch the genital area with its snout. The stallion will try to nuzzle the mare. This will make the mare more comfortable with the idea of mating and increase the likelihood of the mare permitting it.
Guide the stallion very slowly toward the mare and allow it to begin mounting.
Pull the stallion gently off of the mare once it groans. The groan is a good way to know whether the stallion has ejaculated because horses do not thrust. This will occur within a minute or two of mounting.
Pull the stallion's reins immediately after copulation to help it dismount, and return it to the stable.
How to Get a Horse to Mate
Mares, or female horses, come into heat during the spring and summer months. During this time, you will have the best chance of getting horses to mate. Mares mate with male horses, or stallions, to produce baby horses, called foals. Assisted mating involves two experienced handlers and a controlled environment. This is often more reliable then natural breeding, which is done in open pasture with no handlers. The best time to start breeding mares is at age four; stallions should start between three and four years old.
