Trying this for my performance gelding and my senior gelding. Already a hit for both boys as I slowly add this to their morning breakfast afternoon snack. I'm hopeful that this adds some weight onto my senior old man as he struggles to keep up in the winters. Hopeful both my boys continue to thrive this winter as we work our way through this bag, as they both really seem to be enjoying this feed. It's super high quality, the smell is tremendous!! Heck I'd like to eat it. Another winner Purina!!

Horses Love It

Every horse I have owned has loved the Omolene feeds. I thought I would try the 400 series as I have an off the track quarter horse prone to ulcers. The feed looks similar to the 200 but with more pellets and none of the sweet. I like that it includes the Outlast product and is low starch giving my boys plenty of energy without being lunatics. I rated it 4 stars as the price point is outside my budget for regular feedings.

Delicious!

My geldings were very happy when I approached them with this feed! It smells great, and by their reactions, it tastes even better. My boys are short draft mixes

My geldings were very happy when I approached them with this feed! It smells great, and by their reactions, it tastes even better. My boys are short draft mixes and I do extensive trail riding with them. If I use this grain daily they would gain too much weight so I save it for the warmer months when we do a lot of riding and add it to their regular grain. It has good ingredients at a decent price.

Happy healthy horse and boarder !

Purina Omolene 400 complete feed has their guaranteed outlast and amplify mixture flaxseed and rice bran for gastric health and fatty acids. The low protein 12% feed I can find to feed a boarders senior girl with kidney disease. Good for a horse that is hard to keep weight on and supplement her forage. I highly recommend Purina products for all my animals! Dogs, and our cat.

My old gelding is on a senior feed but I decided to give this a try. He's not an easy keeper. I have to say I'm pleasantly surprised. Here loves this feed, I can barely get it into his bucket before his big head is in there. With only his few remaining teeth he isn't dropping it all over the floor. I will be keeping him on his extruded feed but will be adding this as a supplemental treat mixed in.

This feed has multiple elements that I really like. It contains the GI support with outlast, it is high fiber, and it contains some added fats. I like to provide extra fat to my off track TBs, I think it helps them better maintain weight. They do well with beet pulp and seem to enjoy the flavor of this feed.
