Table 2 Effects of dietary fermented soybean meal (FSBM) replacement and/or Enterotoxigenic Escherichia coli (ETEC) K88 infusion on growth performance and fecal consistency in weaned piglets 1, 2

From: Dietary fermented soybean meal replacement alleviates diarrhea in weaned piglets challenged with enterotoxigenic Escherichia coli K88 by modulating inflammatory cytokine levels and cecal microbiota composition

  2. 2 - ETEC K88 = infusing the phosphate buffer saline; + ETEC K88 = infusing the ETEC K88; - FSBM = control diet with 24% soybean meal; + FSBM = test diet with 6% FSBM added at the expense of soybean meal
  3. 3 Faeces were scored as follows: 1, watery, mucous-like; 2, loose, semi-liquid; 3, soft, partially formed; 4, slightly soft; and 5, hard. The fecal consistency was calculated as [(Σ fecal scores for 6 days ETEC K88 challenge)/n]
