Is Cod Liver Oil bad for a horses health?
There are no studies on the metabolism of cod liver oil in horses. But since horses do not eat fish, it is likely that they are not designed to metabolize the types of fatty acids found in fish oil, so why take chances? Corn oil is known to be safe and well metabolized in horses. Just be sure to gradually introduce it a few ounces at a time while the body cells adjust to metabolizing it. If your horse develops diarrhea at any point, cut back on the amount. Average 1000 lb horses can handle up to two cups a day for weight gain. For a shiny coat, much less is needed.
