Table 4 Supplemental effect of mixed probiotics on sow and weaning dietary treatment on the growth performance and cytokines response in weaning pigs challenged with E. coli K881,2

From: Dietary Bacillus spp. supplementation to both sow and progenies improved post-weaning growth rate, gut function, and reduce the pro-inflammatory cytokine production in weaners challenged with Escherichia coli K88

  1. 1A total of 40 crossbred weaning piglets weaned from CON and PRO group sows were used for E. coli challenge study (two weeks later)
  2. 2Weanlings were assigned to pens and pens were dispensed to dietary treatments in a spilt-plot pattern. Sow and weaning dietary treatments (CON and PRO diet) served as main and sub-plot respectivelyt
  3. 3,4Sow and weanling dietary treatment consisted of corn-soybean mean-based control diet and control diet supplemented with 0.05% of Bacillus subtilis (FXA and PB6) and Bacillus licheniformis probiotics. Additionally, weanlings were orally administered with a 1.5 ml suspension of 1,010 colony-forming units (CFU) of K88 strain of E. coli per ml
  4. a,bMeans in the same row with different superscripts differ significantly (P < 0.05)
