The world of swine production is in constant motion. Developments continue to occur, influences happen from all kinds of directions, and bigger pictures come and go. When asked to identify “trends” in livestock production and meat consumption, they suddenly appeared to be plentiful. The Oxford Advanced Learner’s Dictionary said, “A trend is a general direction in which a situation is changing or developing.” Perhaps not the most scientific source, but Wikipedia added to that, “A trend is a form of collective behaviour in which a group of people enthusiastically follow an impulse for a short period.”
