LOL...this is all so complicated:)
If I understand nutrition right, the amount you feed, isn’t really the problem, is the percentages of starch and sugar in the feed you feed...No matter how little you feed, if the percentages are off, you still get the high rise of insulin when they eat it, which is not good. Will possibly cause insulin resistance and obesity...works the same in humans.
I still believe, but it’s just an opinion:), that you’d be better off feeding strategy then adding supplements. Especially since you don’t know the nutritional value of the hay and pasture. If you trust the maker of the feed, then the assumption is, Strategy is “balanced” and balance is the key.

Tennessee was a prime example of that. I was feeding him not even a measuring cup full of oats each day but he was still blowing up like a balloon. It was mind-boggling.
