I have been feeding 2 quarts of 10% sweet feed (approx 3 lbs) and 1 quart of alfalfa pellets (approx 1 lb) to my mare. She is doing fine in last 3 months, but one lady told me feeding Alfalfa everyday 2x a day is not best for the horse. I asked her why? She just said "because I said so." I was like eh, anyway is it bad to feed alfalfa to horse everyday?
That horse eat 5 flakes of brome/orchard mix hay daily along with 24/7 access to mineral salt, water, and grass to graze.
