Siman, My answer would be yes. The only exception would be if more preferable forage was being grown nearby. Bowman is right about a hayfield that is not cut being a preferred place for does to have their fawns. But as far as more deer activity, a cut hayfield is better. Clover and grass grow good together, but once the grass matures it hinders the clover, and clover thrives with frequent cutting. With a field that size and depending on what type of clover is growing (preferably red/white or both) you should see a lot more activity. IMHO.
