dc.description.abstractPost-weaning diarrhea is a major health challenge in the swine industry and is routinely managed by fortifying pig starter diets with antimicrobials. But there are concerns about antibiotic resistance, hence the need for identifying effective alternatives. The use of spray-dried whole egg powder containing anti-F4 antibodies (SDWE) against recombinant F4 antigens and chitosan oligosaccharide and Enterococcus fecalis probiotic combination (CPRO) was investigated in two trials using enterotoxigenic Escherichia coli K88+ (ETEC) oral challenge model in 21-d-old piglets. Pre-challenge, SDWE supported higher (P < 0.05) piglet performance whereas during the post-challenge period, SDWE and CPRO had no effect on growth performance but diarrhea incidences and severity were reduced (P > 0.05) in SDWE-fed piglets compared to the control. The results show that SDWE supported greater piglet performance pre-ETEC challenge although there was no benefit of SDWE or CPRO supplementation evident during the post-challenge period in early-weaned pigs.en_US
