We have a 5 year old QH gelding that tends to be on the lazy side. I know he's capable of being pretty fast because occasionally, when the herd is playing in the pasture, he's quite the athlete. Just when we ride him he's pretty slow and doesn't seem to have any desire to go any faster. His body condition looks good. I was thinking about whole oats. I know race horse stables feed oats and most performance horse farms that I know of do as well. I don't want to fatten him... just increase his energy level. What are the disadvantages of feeding oats and does anyone have any other suggestions? Thank You.
