I personally don't like complete feeds. You have to feed too much for full nutrition. You can make your own senior feed pretty easily! Here is what the old guys at my boarding facility get, and they are doing awsome!
- 4-6 lbs of alfalfa pellets
- 2-3 lbs of soaked beet pulp
- 1-2 lbs of stabalized rice bran
- Source Focus SR (especially for senior horses)
- Purina's Free Balance
- (one guy, who has joint issues) Next Level's Joint Liquid
You can also add in some plain oats (your choice of crimped, rolled, or whole, they all work about the same). The rice bran gives the fat you need and helps balance the Calcium Phosphorus ration in the alfalaf pellets. The Source is a probiotic that helps the horse digest his food. The FreeBalance is a vitamin/mineral supplement for horses not getting any fortied feed. You can also feed Sellect II or Smart Pak's Smart Vite. Both do the same thing.
Now, if you just have to have some kind of commerical feed, then I would recommend a Ration Balancer. They are very concentraed and high in protien. They are designed to be fed at only 1-2 lbs a day for FULL nutrition. Triple Crown really has the best one, but they are not the easiest feed to find (race tracks like them, so if you are near one, check the feed stores around the track). But, almost every feed company except Nutrena makes a ration balancer. Purina's is called Born to Win. You can reduce the alfalfa pellets and remove the vitamin/mineral supplement if you feed a ration balancer.
As for Ultium, it didn't do anything for my Anglo Arabian, who was a hard keeper. I put him on a similar diet as above (though no beet pulp and more alfalfa) and he gained weight much nicer! And his coat was very nice as well. The rice bran is high in fat and nutrients to balance the alfalfa.
Also, unless you're feeding the recommended amounts list on the side of the bag, your horse isn't getting full nutrition. And the recommended amounts are "minimum" requirements, not "optimum" nutrient levels.
