Omega-3 and omega-6 fatty acids are essential fatty acids, meaning that the body needs these substances but cannot produce them itself. Fatty acids must therefore be absorbed from feed. Essential fatty acids can be found in vegetable oils, nuts, and grains. Omega-6 fatty acids are mainly found in soya oil, grains, and seeds. Fresh grass, linseeds, olive oil, and rapeseed oil are high in omega-3 fatty acids.

These days, most horses get sufficient omega-6 fatty acids from their feed; the cereals in mueslis and pellets contain ample amounts of this fatty acid. When horses spend most of their time in the stable or when grazing is largely impossible (in winter, for example) they often get lower quantities of omega-3 fatty acids . It is important that the ratio of omega-3 to omega-6 remains in balance. If the ratio of omega-3 and omega-6 is right, the horse will automatically produce enough omega-9. A correct ratio of omega-3 and omega-6 fatty acids is beneficial to the immune system as well as to the horse’s overall health.

An imbalance between these fatty acids may lead to inflammation, poor coat, reduced resistance, and reduced fertility.
