I like Strategy. It is the same type product as Nutrenas Safe Choice. I think it is a good "all purpose" horse feed. However for specific things I go to other feeds. Like I LOVE LMFs "gold" and sr feed. Gold is high fat high calorie. Been great for fattening up our rescues. Thier SR. Is by far better than Purina Sr.
I am now trying the new Amplify growth for my weanling, She loves it.
But for just a normal horse with no special needs I like Strategy. I use it when I need just a little weight on a horse, or they need just a lilttle extra.
