Oils containing fish oil are highly unpalatable for horses unless heavily processed. Horses evolved on grass not fish, so a plant based source of Omega 3 aligns with nature. Many contain flavours or vegetable oil blends to mask the rancid fish smell. Garlic is also used to mask the smell, but there is recent research to suggest that doses of garlic much less than first thought may negatively affect red blood cells in horses. Omega 3 is essential for overall health particularly beneficial for brain, nerve and muscle function, the immune system, coat/skin, joints and hooves. Dr. Juliet Getty – highly regarded and internationally respected, independent equine nutritionist writes – “Omega 3s block the formation of inflammatory molecules that are readily formed from Omega 6s. Take a close look at the fat sources you are feeding to confirm that enough Omega 3s are in the diet.”
