What horses are at the highest risk of vitamin E deficiencies?
- Performance horses that are competing and traveling regardless of turnout
- Horses of all ages that don’t graze on good grass for at least 12 to 17 hours per day
- Horses on restricted diets
- Horses grazing on winter pasture
How do you determine if your horse is deficient?
- The best way to tell if your horse is deficient in vitamin E is to have your veterinarian draw a blood sample, which will tell you the exact level of vitamin E in your horse’s system.
