hogs and hay

I usually only raise my hogs on whey grain and water. Finishers in the fall get some pumpkin and apple in the mash for a treat. I just like the the way a Yorkshire raised and finished on grain tastes. The other day I threw some hay from some reclaim acres in the pens for bedding. Darn hogs left their mash and started tearing up this mess of goldenrod burdock briars old orchardgrass and fescue. They love it. Is there something the supposed complete ration from the feed store is lacking? The ration is based on ddg soy corn and alfalfa meal Beet pulp mineral and vitamin package. They have been gaining well as always. Manure is fine.
