Heifer nutrition?

[southernultrablack]

Have a group of heifers set to calve starting Feb.10. They are currently on free choice mineral (purina wind and rain all season) mixed grass hay and about 3 pounds of 22% protein supplement per day 50%CSmeal25%corn25%salt. Starting in Feb. we will add about 9 pounds per head of an Alfalfa haylage. Should I continue with the supplement mix as it is or switch to something higher in energy? I want to keep these girls in good shape for breeding back.

If they are in a BCS of 6 or 6.5 now, I would keep them as they are until they calve then gradually increase their ration.
