What are the characteristic risk factors for equine metabolic syndrome?
obesity, insulin resistance, historical or current laminitis
What fat depositions are more predictive of equine metabolic syndrome than others? (2)
tail head, nuchal crest
Gaited horses with EMS are often normal weight or thin, BUT they exhibit...
a gait other than the breed standard gait.
Equine metabolic syndrome is a _________ risk!!!!!
All ________ are at risk for laminitis and EMS.
ponies (under 14.2 hands)
What breeds/species are very insulin resistant? (3)
donkeys, Peruvian Pasos, Paso finos
Insulin resistance tests have _______ sensitivity and _______ specificity; therefore...
low; high; negative results cannot rule out insulin resistance!
What are the goals of diet modification for treatment of EMS? (2)
encourage weight loss (decrease calories), minimize increases in blood sugar and insulin
Why do you want to avoid spikes in glucose and insulin in horses with EMS?
hyperinsulinemia is a high risk factor for laminitis
What dietary carbohydrates do you want to feed to horses with EMS? What kind do you avoid?
- Feed: structural carbs (cellulose)
- Avoid: non-structural carbs (sugar, starch)
Horses with EMS should have free/restricted access to pasture.
restricted (grazing muzzle, short turnout periods)
All components of an EMS horse's diet should have less than _______ nonstructural carbs.
What exercise recommendations do you give for a horse with EMS?
regular, moderate exercise to increase insulin sensitivity and encourage weight loss; not too hard because you can cause laminitis
What drug might you give to an EMS horse to control thyroid, increase basal metabolic rate, improve insulin sensitivity, and encourage weight loss; given temporarily, not long term.
What drug might you give to an EMS horse that increases insulin sensitivity; not well studied yet, not well absorbed orally.
