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.
For cows balanced at 60 pounds of milk, the feed cost was $4.01 per cow per day, cows consumed 44.9 pounds of dry matter and ration costs were 9 cents per pound of dry matter.
