Values are means ± standard deviations. T1, First day of Phase 1 (day 0 post-weaning); T2, final day of Phase 1 (day 40 post-weaning); T3, final day of Phase 2 (day 90 post-weaning).

C, Basal diet; L, basal diet + 1 g/kg of Product 1 containing live Enterococcus faecium; D, basal diet + 1 g/kg of Product 2 containing heat-killed E. faecium; M, basal diet + 1 g/kg of Product 3 containing live Clostridium butyricum; L+M, basal diet + 1 g/kg of Product 4 containing live E. faecium + C. butyricum.
