¹Sows were fed mannan oligosaccharide (MOS, Actigen, Alltech, Inc., Nicholasville, KY) from the 86th day of gestation until the end of lactation (day 20 post-farrowing), and piglets were fed it from day 7 to day 35 of age.

²Dietary treatments: sCON = sows fed control diet; sMOS = sows fed diet supplementation with 400 mg kg⁻¹ MOS; pCON = piglets fed control diet; pMOS = piglets fed diet supplementation with 800 mg kg⁻¹ MOS; sCON-pCON = sows fed control diet and piglets fed control diet; sCON-pMOS = sows fed control diet and piglets fed diet supplementation with 800 mg kg⁻¹ MOS; sMOS-pCON = sows fed diet supplementation with 400 mg kg⁻¹ MOS and piglets fed control diet; sMOS-pMOS = sows fed diet supplementation with 400 mg kg⁻¹ MOS and piglets fed diet supplementation with 800 mg kg⁻¹ MOS.

³S, sow dietary treatment; P, piglet dietary treatment; and S × P, the interaction effect of the sow and piglet dietary treatments.

⁴No., number of piglets; log10 counts of Lactobacillus, E. coli and total bacteria.

^a,bMeans in the same row with different superscripts differ (P < 0.05) between the same dietary treatment.
