Diarrhea rate (%) = the number of diarrhea pigs × diarrhea day/(the total number of pigs × experiment days); in the same row, values with no letter or the same letter superscripts mean no significant difference (p > 0.05), while values with different small letter superscripts mean significant difference (p < 0.05).
