I'd say if your planning on breeding at one point be sure you look into genetic heritable diseases, you may need to test for these or make sure your stud your breeding to doesn't carry these diseases. I'll give a brief description but I recommend reading about each one further on your own.
Diseases related to color.
OLWS/LWO- caused by foal inheriting two copies of frame. Frame is in multiple breeds not just in paints its also found in QH's which I'm assuming your planning on breeding to. It also may not show up on the coat it can even be on solid color horses. Two copies of frame (homozygous) is ALWAYS lethal. Frame is testable.
CSNB- congenital stationary night blindness (I don't know a lot about this one but I believe it associated with the leopard complex in appaloosa's.) just in case you wanted to breed to an Appaloosa
Splash- can sometimes cause congenital deafness.
These are the diseases that you definitely need to learn about! HYPP, HERDA, GBED are all testable sometimes stallion owners lie about the status of these diseases a good way to check further is check out the offspring!
HYPP- Hyperkalmic Period Paralysis: this is associated with horses related to the stallion Impression. If breeding to any Impressive bred horse be sure the horse has been tested and confirmed N/N for no HYPP. Causes sporadic attacks of muscle contractions and convulsions and can be so severe it kills the horse. Be aware some breeders lie about thier studs HYPP status.
HERDA/HC- Regional Dermal Asthenia/Hyperrelastosis Cutis: recessive hereditary skin disease. These horses have loose hyper-extensible skin, poor wound healing, lesions, fragile skin. Horses are usually put down when discovered to have this disease as they suffer from chronic skin infections and cannot be ridden, they also have horrible disfiguring scars. This disease is associated with Poco Bueno and his sire King.
GBED- Glycogen Branching Enzyme Deficiency: foals are born lacking the enzyme to store sugars causing the brain, heart, and muscles to slowly die. This disease is again associated with King and his sire Zantanon. This is 100% LETHAL.
ERU- Equine Recurrent Uveitis: causes blindness in horses associated with Appaloosas, thoroughbreds, and Standardbreds. No test for this but can be found in the offspring.
I think I covered the one's you need to worry about are there any I'm forgetting I feel like I'm forgetting something lol. Posted via Mobile Device
