Corn Stalks: how do I figure about how long corn stalks will last with 125 bu corn on 55 acres for 83, 1200 pound cows?

Nrcs range tech note 6 covers this. 120 bu corn is about 1.7aum/ac. I went by 1 ac per cow per month

I use the rule of thumb of 1ac per cow per month, assuming spring calving cows in good condition. The longer the cows are on the same field, quality of the forage will decline as they eat the grain and leaves first at some point you may supplement some protein once they are just consuming the stalk portion of the plant or if they need more conditioning.

I figured a cow eats 3 percent of her body weight per day. So about 40 lbs per day for your 1200 lb cows. Theoretically there are as many lbs of corn stover per acre as there was pounds of grain harvested. 5600 lbs of stover per acre on 100 bushel corn. My experience is to let the cows eat about 1500 lbs per acre. Rule of thumb is about one acre of stalks per cow per month with corn yields in that range.
