I was previously feeding my horses Strategy but my gelding kept choking, so I took him off the pellets and just on a 10% sweet feed and alfalfa. However, a friend of mine suggested what she feeds, COA. Corn, oats and alfalfa mixture...she also puts a little rice bran. I had thought I had heard corn is hard for horses to digest so I wanted to get some opinions. Also any opinions on any different feed to switch to. Both of my horses are pretty easy keepers, but I have noticed my mare has dropped a little weight since she's been off the COA. Thanks!
