New Mexico | Depends some on the quality of your silage.
That stuff w no grain in it is filler if that.
Cow will eat 2.5 to 3 lbs air dry feed per 100 lbs of her body weight ( if she's running out she'll eat less fed feed ).
Silage is 65% h2o. SOO takes bout 3 lbs of silage to equal 1 lb of air dry feed.
Your going to need to feed some "broom" w it. Say 4 to 5 lbs of ground hay / cornstalks straw or maybe some soy hulls in there.
There's perhaps plenty of cheap poor quality feeds out there this year.
Generally a ration needs 20% to 25% of good high quality ingredients to get real performance in backgrounding cattle etc ( cows course can get by with less because all they have to do is maintain until the third trimester).
She needs REAL groceries as a P 3 because that's when 70 to 75% of in utero calf development happens.
Keep in mind one can sell cows and simply double up on hiefer calves ie keep em over.
Same amount of feed for 1 cow will rough background 2 to 3 lite calves.
