1 Groups: NC—negative control; CBL-V—vaccinated, not challenged; CBL-V/O78-C—vaccinated challenged with E. coli O78; CBL-V/O125-C—vaccinated, challenged with E. coli O125; Lector+O78-C—Lector three days before challenge with E. coli O78; Lector+O125-C—lector three days before challenge with E. coli O125; PC-O78—positive control E. coli O78 challenge, PC-O125—positive control E. coli O125. 2 Scores are expressed as mean ± standard deviation. 3 Abbreviations: FCR—feed conversion ratios; dpi—days post infection. a–d Means within the same column with different superscript are significantly different at p-value < 0.05.
