At the 2012 Minnesota Pork Congress, Dr. Lee Johnston, professor of Swine Nutrition and Management at the West Central Research and Outreach Center of the University of MN presented research on dropping nighttime temperatures in the nursery and lowering fuel costs some 20%. However, how you lower the thermostat and the health of the pigs are significant considerations. Dr. Johnston's full presentation and others will be online soon at SwineCast.com/ConferenceConnection.
