My OTTB hard keeper will stand by his stall all day waiting for alfalfa hay instead of eating off his 5 acres of lush green grass. Not to mention the fact that he won't even touch grass HAY. Typically I would stop feeding a horse alfalfa and just force them to eat the grass out of hunger but this horse will just lose weight and he is already a little underweight. Other horses have thrived on our pasture so I don't believe there is anything wrong with the taste of the grass. Anyone have any suggestions on how I can encourage him to forage off his pasture? Currently, I am feeding him 10 lbs of soaked alfalfa pellets a day to supplement the pasture, but he acts like he is starving when I come to feed him the pellets. And I would like to see him put on a little more weight.
