It makes me cringe when people talk like this. Maybe in the Good ole' days" pelleted feed was not good for the horse, but science has come so far!! Pelleted feed (mostly good, higher end feed) is a good source for vit. And min. As well as some roughage. Hay, of course should always be free choice if you don't have a good grass pasture.
As for mineral blocks...if your horse is not getting the sodium intake it needs ESPECIALLY in the summer, it will find sodium. It will strip your trees and it will eat dirt to find it. Horses HAvE to have it just as we do! Mineral blocks are NOT filled with molasses and sugars. You need to get a good solid SALT block or even the reddish brown mineral blocks as it has some of the trace minerals horses need as well..... Another HUGE concern is if you ride in the heat of the summer and not give salt, you are going to have some major problems!! You could also go the electrolyte round....
