Well, being a Purina fan:), it is what I would use if I had pasture or fed hay.
I believe duchess uses it also, for all her horses.

Yep, horses here get alfalfa hay and strategy except Prez and Tuffy. Prez gets alfalfa pellets, equine senior, beat pulp and some supplements. Tuffy gets alfalfa hay, strategy and oats (the oats for weight without heat). The pregnant mares will go on mare and foal their last three months. We have selenium blocks out for everyone because our hay here does not provide enough. And mineral/salt blocks.
Strategy doesn't necessarily cause heat, it's just that to give Tuffy enough to put weight on and keep it with all of his work, he would get too much. There are two strategys, one for feeding with alfalfa and one for feeding with grass.
