Re: Average hay consumption. A cow needs about 3 per cert of its body weight in roughage a day, a 1000 lb cow needs 30 lbs of hay if it has no other source of roughage.
If the same group of 1,200-lb. cows were fed a ration where part of the ration called for corn silage to be fed at 10 lb. per head per day on a DM basis and the corn silage is 35% dry matter and 65% moisture, the pounds of corn silage in the diet would be 28.5 lb. (10 Ã· 0.35) per head per day on an as-fed basis.
