Ultium is a reasonable textured feed for senior horses. Textured feed is beneficial to horses that may experience choke. I would’ve liked the feed, though, to have had a bit more moisture to it for our old man. Our senior quarter horse found the feed to be palatable and readily devoured it. The low sugar formula means that the energy he gets from it is cool not hot. It’s has ActivAge technology which promotes healthy aging, supporting mobility, metabolism, and immune function, Outlast gastric support technology, which enhances gastric comfort with seaweed-sourced calcium and magnesium, AND antioxidants, fat, and highly digestible fibers to support a healthy coat, skin, and hindgut health. We feel the our old man is getting everything he needs.

My two miniatures are not athletes, but my mare is an extremely picky eater who needs extra calories due to her health ailments. The taste test of this feed showed me that it is extremely tasty to my animals. I feed a low starch, low sugar feed now and the Ultium was so well received that I am switching to it. I believe it will give my mini mule and mini mare the nutrition that they need and having them enjoy the product is a relief. My mare hasn't walked away from her food dish once since having the Ultium in it with her current feed.

Protein, fat, and fiber! Finally!

I run a boarding/lesson/sale/breeding barn and I’m loving this feed. I typically feed another product similar in protein and fat and supplement with an alfalfa pellet for the fiber. This has the added fiber built right in, simplifying the feeding routine. I had noticed a positive difference in my OTTB and an older QH mare that I specifically have been feeding it to.

So far, I’m very happy with Purina Ultium Senior. One of the first things I noticed is that it doesn’t seem overly heavy on molasses like many senior feeds. It also stays easy to scoop even in cold winter temperatures, which is a big plus during daily feeding. I like that this feed includes Outlast gastric support and has a lower feeding rate compared to other senior feeds, making it more cost-effective while still offering digestive support. My horse enjoys the texture and eats it willingly. He has only been on this feed for a short time, so it’s still too early to say how well it will help him maintain weight long-term. Overall, this seems like a well-formulated senior feed, and I’m optimistic it will work well for my harder keeper as time goes on.

Perfect for the Unique Needs of the Senior Horse

Purina has truly set the bar with Ultium Senior. This isn’t a generic maintenance feed; it is a high-performance, calorie-dense powerhouse specifically engineered to address the physiological shifts that come with age. While it is fundamentally designed to fuel the senior athlete who requires a more sophisticated nutritional approach, I have found it so effective that I now use it for all my adult horses. It provides a level of condition and stamina that benefits every horse in the barn, regardless of age. The real magic in this bag is how it handles the "hard keeper." As horses age, their digestive efficiency often dips, but even for younger adult horses in heavy work, maintaining a topline can be a challenge. This formula counters that with a high-fat, high-fiber profile that provides "cool" energy without the sugar-induced heat or behavioral spikes. The standout feature is the Amplify high-fat nuggets. These aren't just extra calories; they are a concentrated blend of vegetable oils, flaxseed, and rice bran that deliver incredible "bloom" and stamina. Since adding this to my program, the difference in coat shine and muscle definition across all my horses is night and day. Beyond the fat content, Purina has packed this with their top-tier technology to cover every vital base: ActivAge Prebiotic: Specifically designed to support the aging immune system, mobility, and metabolic health. Outlast Technology: Provides consistent gastric support to keep them comfortable under the stress of work or travel. Highly Digestible Fiber: Uses sources like beet pulp and alfalfa to support hindgut health, making it much easier on the digestive tract. For any horse with high energy demands or an owner who wants their string looking in peak condition, Ultium Senior fits the bill to a "T." It’s highly palatable, licked clean every time, and provides the exact fortification needed to keep a horse looking and feeling like they're in their prime.

I just started using this, so hard to review an Item I have only given a small amount of it to my horse. But, as far as appearance, it looks good, no holes in the bag, no clumps or moisture. It smells good, and my horse did seem to enjoy the little bit I gave her-It came within about a week, so pretty quick delivery. We shall see over time as this cannot truly be reviewed on one bag alone.

My 30 year old mare is super picky about her grain, she was eating Tribute Senior Sport and Kalm Ultra mixed to up the fat content for her. She does have Cushing’s

My 30 year old mare is super picky about her grain, she was eating Tribute Senior Sport and Kalm Ultra mixed to up the fat content for her. She does have Cushing’s so I was excited to try something that had a better fat content than Kalm Ultra and much lower NSC and hoped my picky eater would still like it. She absolutely loves this food!
