Senior Horse Feed comparison

I have a senior horse who has been losing weight. He has plenty of energy and is getting more feed than my other three larger horses combined. I have been feeding him a senior formula feed, but wondered it it was the right one. After horse sitting for a friend down the road and noticing that her once extremely thin aged mare was looking good on the feed they were giving her, I decided to do some research. So, for any and all of you who might want to compare senior feeds, here are a list of their perspective ingredients. I have been feeding Blue Seal and am about to switch him to something else to see if there is a change. I love the Blue Seal product for my other horses as it keeps them in good weight. They are not hard workers, but do climb up the back of Holts Peak here in NH quite often. We shall see if changing feed helps the old guy or not.
