Purina's Wellsolve L/S is very good. I had my older gelding on it for a while. I switched because I wanted all my horses on the same diet, so I switched to a concentrated feed called Barn Bag for Performance horses by Life Data Labs, inc and mix it with either whole oats or beet pulp (less sugar than oats). I feed about a cup and depending on the energy needs, the oats or beet pulp may vary. Of course, my horses are on pasture 24/7. Very happy I switched and the nutritionist I spoke with at Life Data was very helpful.
