As populations expand into rural areas, more people are turning up their noses at malodorous livestock operations.

With funding from the U.S. Department of Agriculture's Cooperative State Research, Education & Extension Service, Alan Sutton and colleagues at Purdue University, Michigan State University and the University of Missouri developed and implemented diet modification strategies that reduce nutrient excretion and enhance air quality around pork operations.
