I feed both my full sized horses plenty of hay (about 20 lbs in the stall and they have a round roll out in the pasture) since we don't have much grass growing in winter. They both get grain as an additive, and I use a 12% protein/21% fiber/4% fat sweet feed and alfalfa oat pellets, but because the feed store closest to me closed down I've had to start using Tractor Supply. I can get an identical sweet feed for them but our Tractor Supply doesn't carry the oat pellets. So, I switched the horses to alfalfa oat cubes. I'm not sure how much to give them though! They get about 1 1/2 lbs of sweet feed and 1lb of pellets usually, but I'm wondering what the ratio change for the cubes would be? And my Percheron keeps a pretty healthy 6 body score but my mare (who gets a bit more sweet feed) is between a 4-5 and I want her a bit chunkier.
