My weanling gets Triple Crown Growth - 1 lb per 100 lbs of body weight twice daily (5 lbs twice daily in my case) . O & A or T & A - usually 2 lb per 100 lbs of body weight (ends up being almost free choice) and they get it when they are in the stall. Turn out in small short grass pasture at night and in stall in the day.
He is a 6 month old halter colt and will be shown in a couple of months.
He is also on dac Colt Grower and dac Bloom. All of mine get dac 911 3 to 5 days before and after worming and anytime I am going to stress them (move or showing, etc....). You can search
Omega Horse Solutions if anyone wants to see the write-ups.
