I am about to get pigs again after a break of 6 years and last time we just fed organic pelleted feed. This time they will be in a 1.5 acre field of pasture and gorse and I'm hoping to feed fewer pellets. They will get some goats milk and barley plus some pellets. Will I need to give supplemental minerals?
Our soils are complete according to the soil tests but I have discovered over the years that I get an increase of one piglet per year if I also feed kelp. It doesn't take much, about a quarter ounce per hundred weight per day. See:
