There is a new rule from AQHA that all breeding stallions now have to have a Five Panel Test in order that their offspring can be registered with the American Stud Book.
The five-panel genetic test covers:
- glycogen branching enzyme deficiency (GBED)
- hereditary equine regional dermal asthenia (HERDA)
- hyperkalemic periodic paralysis (HYPP)
- malignant hyperthermia (MH)
- polysaccharide storage myopathy (PSSM)
The effects of these equine diseases are wide-ranging, from mild and manageable to severe and terminal. Passing these diseases on to successive generations often causes unnecessary suffering and also leads to financial losses for horse breeders.
