Help me choose a feed for my hard keeper.

Thanks everyone! I'll look into senior feed and possibly some beet pulp.

Nutrena did not show What they use in the product. It did show higher fat % which is good. I don't like the fact that it does not state if it wheat, rice or corn etc. Where is the protien coming from ? The fat ? Animal by products???
What I could see, this does not show . I would read the entire label, wheat, middlings etc and see how they compare. I use LMF feed for my senior horses it helps the weight and joints. I also use all in one and add Corn oil for additional fat. I did the beet pulp, but did not want all the Sugars.
