Free: Contests & Raffles.
Not a pro buy any means and I'm sure a few will chime in here. With that said, I have called in multiple cows in my archery hunting years. Calf calls work great....especially if you find a small group of cows. Oddly enough, the cow and calf calls will also draw in spikes and small bulls. A bugle will just scare away a spike and I have never called in a cow with a bugle either. I would stick to cow and calf calls.
The only things that I’ve called in with distressed calf has been bears. They may work for cows, but keep alert. Don’t be surprised if a bear pops up 10 yards from you.
The call of Free Doughnuts really brings in the cows.
Cows will come in to investigate new animals in the area. Get near the herd and blow a bunch of cow calls, stomp around and then set up for the shot. You never know what will show up, but cows will be in the mix. Same holds true for spikes.
