Significantly higher fecal consistency scores in PEDV-inoculated nursing pigs compared to PEDV-inoculated weaned pigs at PIDs 1-5. After PEDV inoculation, pigs were monitored for clinical signs 2–3 times daily until necropsy. Diarrhea was assessed by scoring fecal consistency. Fecal consistency was scored as follows: 0 = solid; 1 = pasty; 2 = semi-liquid; 3 = liquid, with scores of 2 or more considered diarrheic. Each bar represents the mean ± SEM. **, P < 0.01 (statistically significant differences between the PEDV-inoculated nursing and weaned pigs by Student’s t-test).
