Cows and deer mostly ignore eachother, some times they will stare at you and alert the deer, but horses will give you away every time if they know you are there, and will follow you if you move. I would hunt inside the edge of the woods, the deer will for the most part follow the edge of the woods, skirtting the edge of the cow pasture, If they move in with the cows, they will be moving pretty fast. They get along, but they don't like eachother.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
