Retinyl Propionate (Vitamin A) - Feed Ingredient
Retinyl Propionate is a synthetic ester of retinol (Vitamin A) and propionic acid. It serves as a stable, fat-soluble source of Vitamin A in animal feeds and supplements, including those formulated for horses. This form is more resistant to oxidation than unesterified retinol, improving its shelf life and effectiveness in feed applications.
In the equine diet, Vitamin A is essential for normal vision, immune function, reproduction, and cellular integrity, especially of epithelial tissues. Horses typically obtain Vitamin A from beta-carotene in green forages, but supplementation with preformed Vitamin A like Retinyl Propionate is common when for when horses are not exclusively on fresh green forages.
The following equine feeds, supplements and products contain Retinyl Propionate (Vitamin A) as an ingredient.
