The pigs have large acre paddocks to roam in giving them the freedom to display natural behaviours like rooting in the soil and playing with their peers. This extra space and activity not only ensures a vastly improved standard of living and welfare, but it also results in the pigs growing at a slower rate. This is for the simple reason they are burning off more calories than a pig that is sat in a concrete pen all of its life. By growing at a much slower more natural rate, the pork acquires a flavour and succulence that pork used to have.
