I have a 6yr old 15.1 hh ranch type APHA mare. I ride her 4-5 days a week either 30 minutes of intense work in the arena- working barrels, loping, long trotting, stops, rollbacks(plus a warmup and cool down) or 4-5 miles on the trail in about 30-35 minutes(and then a long walking cool down). She is a 24/7 freechoice hay with a slow feeder net and maintains a nice weight with her current feed(pretty easy keeper) I feed her 1.5 pounds of whole oats once a day(slowly working up to two) and about 1.5 cups of this stuff. Conditioning Supplement | Masterfeeds as a top dressing plus 1 tbls of salt(cause she was constantly licking her block) I would like to add a little something for a fat boost. I am thinking maybe flax seed but someone has mentioned flax appeal. Any advice?
