The rate of diarrhea among 4- to 14- day-old pigs was one case per day per 250 piglets. Diarrhea mortality averaged one death every 2-4 days for 250 pigs. Diarrhea increased with: herd size, sow health problems, deworming sows in the harrowing crate, and routine use of supplemental milk for piglets. Diarrhea decreased with: all-in-all-out harrowing rooms, washing sows, TGE-free herd status, and vaccinating sows against Escherichia coli. Diarrhea mortality increased with: litter size, sow health problems, fostering piglets at 4-14 days of age, and sow mange/lice treatment while in the harrowing crate. Diarrhea mortality decreased with: fostering piglets out of the litter at 1-3 days, using supplemental iron, using a hired manager in the harrowing facility, and E. coli vaccination. The factors not associated with diarrhea morbidity and mortality included: vaccinating piglets, clipping teeth, docking tails, feeding the sow antibiotics, harrowing problems, operation type, supplemental creep feed, vaccinating sows against TGE or rotavirus, treating navels, facility type, and using a consultant such as a veterinarian, nutritionist, or extension agent. We conclude that vaccinating sows for E.coli and fostering piglets off sick sows are expected to decrease preweaning losses due to diarrhea in 4- to 14-day-old pigs. ER -
