We analyzed data collected in the National Swine Survey to find the management variables that may affect preweaning piglet mortality. We also considered other recently reported significant facility variables in our models to expand and unite the two independent investigations. We found that techniques (all-in--all-out and cleaning between groups) which should reduce the exposure of suckling piglets to the pathogens of older or previous inhabitants to be more strongly associated with reduced preweaning mortality than methods to increase immunity or reduce parasites.
