I feed all of mine Safe Choice. I have a MFT that is prone to colic. Had collicked 4 times in one year and it was bad. I switched his whole feeding regimen and he hasn't collicked since. It's been 8 months. I also fed this to my QH/Arab who was a hard keeper. He finally sustained his weight on the Safechoice. The only one I am currently having problems with on this feed (STILL NOT CONVINCED IT'S THE FOOD) is my TWH. She is pretty hyped up, but has been since the day I got her. It also helped my OLD QH ranch horse gain weight after losing many of his teeth. It's a pretty good feed for an overall feed. Then you can add whatever you need for each horse if this is doable.
I'm so glad you were able to find the ingredients on the Safe Choice bag, as I have been accused of lying about finding a complete list! HHMMMM, looks like they do print their ingredients on the tag! I was also told this was not a good food as it had too high of NSC's....hhmmmmm!
