It depends on what temperament your cows are, I’ve managed and hunted around cattle since I can remember. I watched a group of Brahma momma cows stomp/run a boar hog out of a pasture one morning, they would do the same to a group of turkeys. 2 miles down the road I have a group of docile angus who always have turkeys hanging around them. Horses and donkeys don’t get along with turkeys from what I’ve seen but it’s all anecdotal evidence of course. Cattle do better for the land than letting it go fallow but some herds act different in relation other animals from what I’ve seen
