I'm just a grain farmer, but in the highly competitive agriculture world, fortunes are made and lost on seemingly small efficiencies. If the savings on antibiotics and deaths were actually greater than the alternative costs, someone would quickly exploit the gains, and everyone else would eventually be forced into that model to compete. Which is the same reason why you see barns going up everywhere instead.
