This week I am joined by special guest, Dr. Katie Young, an equine nutritionist who consults for Kentucky Equine Research and who councils clients independently. Dr. Young has spend her career in the equine feed industry and is a wealth of experience an knowledge! This week, Dr. Young talks about Myofibrillar Myopathy (MFM) in horses. We'll discuss how it differs from polysaccharide storage myopathy (PSSM) (types 1 and 2), what to look for and how to support MFM from a dietary standpoint.

Horses with MFM may present with decreased performance or unwillingness to go forward. Dietary management is quite different from PSSM. Listen in to learn more!
