Instructions
Select the two horses to breed. The male horse (sire) will be a stallion and the female (dam) is the mare. Both horses should have good temperments, pedigrees and performance records.
Have a qualified veterinarian check both the intended sire and dam for anterior segment dysgenesis (ASD) as well as any other health problems. ASD is an eye condition that affects a significant number of silver dapple horses and is believed to be inherited. ASD has been linked to the silver dapple coloring trait. There is no genetic test for ASD and it is possible that the horse could be a silent carrier. Do not breed a horse that shows symptoms of ASD when given an eye exam by a professional. If one of the horses you intended to breed has health problems, select a different horse.
Breed the horses. After you have certified that your sire and dam are healthy and free of genetic defect, choose between natural breeding and artificial insemination. If you want the horses to breed naturally, wait until your mare comes into heat and then allow the stallion to cover her, either naturally by allowing the horses to have sex or by having your veterinarian inseminate your mare with the stallions semen. Repeat the process for as many heat cycles as necessary for the mare to conceive.
How to Breed Two Dapples
The dappled gray or silver dapple coloring is more prevalent in some breeds of horses than others. The silver dapple color has been linked to a genetic eye anomoly that is especially prevalent in Rocky Mountain Horses and other breeds where the silver dapple color is highly prevalent. To breed two silver dapple horses, first perform some basic genetic and veterinary testing to avoid problems in the offspring.
