Have you always fed him grain only a couple of times per week? Cows like consistency in their diet due the the way they primarily digest feed.. the rumen bacteria may become unbalanced if there is a big hit of grain a couple of times per week and insufficient starch digesting bacteria to break it down. Another possible cause for bloat. On the other hand, if it doesn't seem to affect him adversely, I wouldn't be hugely concerned.
