I live in Central NY State on a 165 acre farm, of which about 100 acres is woods. I also raise beef cattle and have raised bunches of dairy heifers as well. I have never noticed the deer getting too close to the cows but many times I see them not too far away. Many times I will see the cattle grazing at one end of a field and deer at the other. In my experience deer are not too averse to sharing pastures with cattle. I had a strange experience last night, during our freak snowstorm that dumped about a foot of wet snow on central NY. I had just fed the cows near my south barn and I was walking towards the north barn to shut the hayloft doors when I thought what I heard was a calf making a one time bawling; it was getting dark and the snow was blowing hard, and I saw the "calf" and figured I had to go shoo it back into the adjacent field to get it back with the main herd, when all of a sudden it took off much faster than any cow would ever do. I then noticed that it was a deer, and why it decided to vocalize like it did is beyond me; so close ti both the house, barns, and the cattle. Maybe it had gotten separated from it's fawn. Just like Charlie A said in the latest D and DH; just when you think you've seen it all, the deer go and do something entirely new.
