Rutgers – Ask the Expert – Pine Nut Oil to prevent Ulcers?

Question:  Would it be safe or effective to feed human grade pine nut oil to my horse to help prevent stomach ulcers?

Answer: Pine nut oil has not been specifically tested in horses. Since they can digest and utilize virtually all other edible oils tested, it may be safe in limited (no more than a cup or two per day maximum) quantities if it is introduced slowly to the diet. There has been research on the efficacy of other edible oils to help with equine gastric ulcers—they do not work. Horses’ stomachs are very different from humans’. The best nutritional strategies to prevent gastric ulcers are to give as much turnout as possible, provide free access to forages (with some alfalfa, which seems to be somewhat protective due to its high calcium content) and to limit grain as much as possible, avoiding large meals of sweet or other high-starch feeds.
