I have some friends that feed something similar its a complete feed per se but it is basically an alfalfa pellet (large size) called Equidyne.. it has corn in it and some other ingredients and added vitamin/minerals.. anyway.. they like it- but they dont have performance horses.. so not sure if it'd work for barrel horse to be all that they needed grain wise.. Im not a huge fan b/c pellet is so large seems like would have a lot that choked on it - and also im not a fan of feeding corn/starchy type feeds.
