Hi, Liz. A general rule is three pounds of milk should get one pound of grain. So a cow producing 30# a day would get 10# of grain. If you've got a cow milking like crazy you might want to boost the grain to 2.5# of milk to one pound of grain. But with excellent forage you probably wouldn't even need that much grain.
Figure on 3% of body weight of dry matter intake. So for a 1000# cow, 30 pounds of DM a day. Which would include grain as well as hay. Since hay and grain run 10% moisture, that would throw it off a bit, but not by a lot. Remember that there is about 10% waste, as well, on the hay. You could probably figure at least 20 pounds of hay as a minimum.
