Mixing species, such as chickens with cows or lambs with beef, on the same pasture can interrupt parasitic life cycles because parasites often require a specific host species.

“in terms of the parasite cycle it's just about parasites need a host and when you have a bunch of cows in a pasture let's say there's ticks or some sort of you know worm or that's a problem for them it once they leave the pasture they and they're gonna come back those parasites will hang out there and wait for their hosts to come back if chickens or some other animal that's not a host that also thinks that they're tasty hangs out there then they will eat all the larvae and you'll have a natural way to break that cycle”
