Remember when I wrote about feeding fat for horses – Feeding Fat in Horses not a fad

That diet was specifically formulated for EPSM or PSSM…well there is new research on that disease which shows that it has a genetic component, which is very exciting! It may be possible in the future to test for that genetic type and eliminate a disease that affects a large percentage of draft horses and a few Quarter Horses. What a way to improve horse health by breeding appropriately and removing a defect. It can be done with HYPP if there was not money involved in keeping that disease around…oops sorry did I say that.
Check out some of this information from the Horse – Polysaccharide Storage Myopathy: Blame It on the Genes 

And the actual paper of the research from PubMed -  Glycogen synthase (GYS1) mutation causes a novel skeletal muscle glycogenosis.
