We have had some great pig breeds in the past including old spots but have been out of the farming game for a number of years. As part of our low input, high profits system based on Joel Salatin at Polyface farm we are looking for grazing pigs which looks like the darker pigs. Looking at feedback from owners who have grass grazing pigs with electric fencing. The pork is very important and wonder if there is much difference in breed with the pork.
