Try giving him free-choice hay/grass until his gut gets back to normal, then gradually start with grain again.
Cattle need a certain amount of roughage in their diet in order to stimulate the rumen and move the food through. My guess is his roughage to grain ration was way off. If the ratio is off it can also change the pH of the gut. It will take some time and lots of roughage to get him back to normal.
