It adds calories without adding grain
When a hard keeper is already eating all the hay he’ll take, the usual next step is more grain, and more grain mostly adds starch. Sheila L. was at that point with her 24-year-old gelding. She “didn’t want to add more grain and he only eats so much of his alfalfa and orchard grass.”
Fat is the most concentrated calorie a horse can eat. The weight-gain dose for a 900 lb (410 kg) horse is 120 mL a day, which is about 1,000 calories. That’s close to what three-quarters of a pound of oats would give him, with no starch or sugar, and it goes on top of the feed he’s already eating. With no starch, sugar or potassium in it, it’s also a safe fat source for horses with PSSM1 (polysaccharide storage myopathy) or HYPP (hyperkalemic periodic paralysis).
