Abstract

<italic>Escherichia coli </italic>(<italic>E. coli</italic>)<italic> and salmonella</italic> <italic>enterica</italic> (SE) infections in pigs are major source associated with enteric disease such as Post weaning diarrhea. The aim of this study was to investigate the effects of <italic>Pediococcus pentosaceus</italic> in weaned piglets challenged with pathogen bacteria. In exp.1 90 weaned piglets with initial body weights of 8.53 ± 0. 34kg were assigned to 15 treatments for 2 weeks. The experiments were conducted two trials in a 2 × 5 factorial arrangement of treatments consisting of two levels of challenge (challenge and non-challenge) with <italic>E. coli</italic> and SE, respectively and five levels of probiotics (Control, <italic>Lactobacillus plantarum </italic>(LA),<italic> Pediococcus pentosaceus</italic> SMFM2016-WK1 (38W), <italic>Pediococcus acidilactici K </italic>(PK),<italic> Lactobacillus reuteri </italic>PF30 (PF30)). In exp.2 a total of 30 weaned pigs (initial body weight of 9.84 ± 0. 85kg) were used in 4 weeks experiment. Pigs were allocated to 5 groups in a randomized complete way with 2 pens per group and 3 pigs per pen. Supplementation of LA and 38W improved (<italic>p</italic> < 0.05) growth performance, intestinal pathogen bacteria count, fecal noxious odor and diarrhea incidence. In conclusion, supplementation of 38W strains isolated from white kimchi can act as probiotics by inhibiting <italic>E. coli</italic> and SE.
