Is fresh pasture a good source of vitamin E for horses? Yes, good quality grass-legume pastures can supply adequate nutrients, including vitamin E, to maintain an adult horse at light work or mares during pregnancy. Lush, early spring pasture is very high in water and protein contents and may need to be supplemented with a high-energy source, such as grain, to meet the needs of horses performing medium to heavy work.
Why is Vitamin E Important for Horses?
Vitamin E is a fat-soluble compound and antioxidant that protects unsaturated fats in the body from oxidation by peroxides and other free radicals. It is found principally in certain plant oils and the leaves of green vegetables, with wheat-germ oil being a particularly rich source.
What are the Symptoms of Vitamin E Deficiency in Horses?
Horses with a deficiency of vitamin E may display several symptoms:
- Mild anemia
- Prolonged malabsorption of fats
- Unsteadiness (ataxia)
- Pigmentary changes in the retina
How Can I Ensure My Horse Gets Enough Vitamin E?
To ensure your horse gets enough vitamin E, consider the following:
- Pasture: Provide access to good quality grass-legume pastures, especially during early spring.
- Supplementation: Supplement with high-quality legume hays, such as early bloom alfalfa, especially for growing or lactating horses.
- Commercial Rations: If sufficient roughages cannot be grown, use complete horse rations tailored to the total needs of specific animals.
What Other Nutrients are Important for Horses?
Besides vitamin E, horses require a range of nutrients to maintain their health and performance:
- Protein: Essential for muscle development and overall growth.
- Carbohydrates: Provide energy for work and bodily functions.
- Minerals: Such as iodized or trace-mineralized salt, are crucial for various physiological processes.
- Water: Horses need access to clean, fresh water at all times.
What Type of Feed Should I Avoid Giving My Horse?
Avoid moldy or dusty feeds because horses are extremely susceptible to forage poisoning and respiratory complications. Silages of all sorts should be avoided since horses and mules are extremely susceptible to botulism and digestive upsets.
