I came across this article in the New York Times about Joel Salatin’s Polyface Farm. It’s an interesting read about raising pigs on pasture. Salatin rotates them through the forests much like he moves his cows from pasture to pasture. This rotation is good for the environment as it gives the land time to rest between each pig grazing (which is more of tilling than grazing). It is also better for the pigs. Moving them to clean pastures reduces disease. Think of your bed. You change your sheets regularly, right? Especially after an illness. Moving pigs to new pastures is like changing sheets. Give it a read when you have a minute.
