I raise red wattles in Southern Oregon and we use management intensive grazing techniques that have become essential to our system on the farm. We use movable electric fencing to provide new pasture to root up every day and feed locally sourced hazelnuts to our finishing stock. Managing pigs is a lot like dating a dozen women — if they all have their needs met they're happy, if not, they'll let you know about it.
In the summer we have a harder time keeping them comfortable than in the winter. I spent all day today essentially irrigating the pigs with a six foot tall sprinkler to keep them cool and moisten the soil so they can root it up uniformly. I usually back fence the wallows that they make after a day or so. I've also been using a tarp shelter set up with four T-posts to give them shade when we're not around any trees.
I keep a blog for the farm. If you're interested in seeing our set up take a gander.
