You can make jerky out of any meat. I've seen turkey jerky and salmon jerky sold.
To make your own, you don't necessarily need a dehydrator. Just slice the meat thin and let it air dry on a wire rack. It will lose moisture and harden as long as it's exposed to the air. This is what happens every time I let meat out in the fridge uncovered - it becomes very hard and dry, almost crusted on the outside. Just slice it thin and air dry like that. You'll get jerky.
