A:   The major concern here is the grain or berry. I assume that there will be plenty of milo heads still remaining in the field. The berry has a very hard outter coat that needs to be cracked for cattle to efficiently utilize the grain. So first impression there is no problem grazing cattle. However, I have seen cows founder when grazing milo fields where ther was a lot of down milo or heads left on the stalks. So I think in this situation, where there are plenty of milo heads available, founder is possible. A possible management strategy, is to cross-fence and limit access to reduce the chances of founder or graze some steers or heifers or cull cows ahead of the pregnant cows.
