I hunt in and around a cow pasture. I have taken 2 does out of the pasture this year and last year my wife and i both took nice 8pts. out of the pasture. I don't think that the deer like the cattle but i don't know that they don't like the cattle either. As for the trail cam I wouldn't be suprised if you have some close-ups of cows, they can be curious. Just my 2 cents.
