Taking a slightly different slant on this question I would offer that the pastures where we intensively rotate cows are some of our best. Certainly the deer mingle with the cows some but the real benefit comes from the effect on the pastures. The Savory rotation system creates high quality grazing for both deer and cattle.
Since you guys are scaring Doug away with your talk of shooting cattle
I'll do my best to take his place.
I think Baker is nailing it with his post about using cattle to improve the habitat. It took me way too long to figure this out, particularly considering I grew up working dairy farms. I always would look at the pastured woods and shake my head at the waste of what could be quality cover, and there's a lot of truth to that. However, there's also a lot of truth to the fact that you can use rotational grazing in a way to actually reboots the plant's growth cycles (keeping them in tender, immature states), help control weeds that the deer don't like, while fertilizing the soil, all at the same time.
I've only been messing around with stuff like that on a couple properties over the last 5ish years. So, I'm not going to claim to have it all completely figured out yet, but I have seen enough to shift my mind set from cattle being the enemy to being a friend, if one approaches rotational grazing as a way to help, not hurt our deer/habitat management efforts.
