【摘要】The aim of this study was to investigate the combined effects of chitosan oligosaccharide（COS） and a microencapsulated Enterococcus faecalis CG1.0007 probiotic（PRO） on growth performance and diarrhea incidences in enterotoxigenic Escherichia coli（ETEC） K88+ challenged piglets in a 14-d study. Thirty piglets,7.19 ± 0.52 kg initial BW weaned at 21 ± 1 d.were allotted to 5 treatment groups（n = 6）consisting of a corn-soybean meal diet with no additive（negative control, NC）, NC + 0.25% chlortetracycline（positive control, PC）, NC + 400 mg/kg COS（COS）, NC + 100 mg/kg PRO（PRO） and NC + a combination of COS and PRO（CPRO）. Pigs were individually housed in cages, acclimated to treatments for a 7-d period and had ad libitum access to feed and water throughout the study, On d 8, pigs were weighed, blood samples were collected, and then orally
