Here is a good article about this subject http://dairygoatinfo.com/index.php/topic,13.0.htmlkelebek said:Yes, I personally would not feed grain. I do not know exactly what it is, but I think it is the protein, that causes the urinary blockage by forming stones.
There are others that know way more then I do about it - but I would look into it.
My bucks do not even get grain. They get pellets (usually timothy/alfalfa) during rutt - but that is it. I did hear that BOSS for bucks can cause temporary sterlility in the bucks also.
Hope this helps and others also help you out to answer some questions.
