I will most definitely suggest clover, you will want to plant something with it though like buck forage oats or winter wheat, the livestock will eat the wheat and oats this fall and you will need to perhaps cut it in the spring a little, that's when you'll discover the clover, which if done right could yield for you for 2 or more seasons without replanting.
This is what I did last season and I don't have livestock but the deer have been enjoying the clover, we watch them eat it and clover is 30% protein, BTW.
I planted a drought resistant clover but I would suggest you plant a variety that includes sweet yellow, which makes a darn fantastic honey.
