My daughters first horse was alot older then we originally thought when we bought him. He was "12" when we bought him, we had him 6 years, and he was, according to the attending vet about 30 when he died.
But that horse could eat nothing but the complete pellets. We owned him in the time frame that I tried to go back to hay and grain for awhile. Anytime I gave him anything but those pellets he coliced bad. If I just missed a feeding or was late with a feeding he coliced. When he died the vets all said he looked in great condition for a horse as old has he was. When I told them what I fed they said that was the reason, the pellets were easily digested. Probably kept him going longer then he would have.

That makes a lot of sense.
