We run a cattle operation here in saskatchewan. Deer and elk jump the fence to get into the cattle pasture to lick the salt blocks and lap up some of the spilt grain. I have no reason to believe deer and elk do not get along with cattle because i have seen them in our pasture eating close together. Some of the biggest deer i have ever seen have been on our cattle pasture so i would have to say if the cattle are moved out by deer season (no risk of one getting shot) then it would be fine to hunt.
