Fructo-oligosaccharides(FOS) are well-known prebiotics that have the potential to improve sow reproductive performance and increase piglet growth. However, previous studies were observed in sole FOS-supplemented diets of sows or weaned piglets and did not consider the sow-to-piglet transfer effect on the performance and diarrhea rate of weaned piglets. This study explores the effects of dietary FOS supplementation on the reproductive performance of sows, and the effects of FOS supplementation at different stages on the growth performance and diarrhea rate of weaned piglets. A split-plot experimental design was used with sow diet effect in the whole plot and differing piglet diet effect in the subplot. Fifty-two multiparous sows(223.24 ± 14.77 kg) were randomly divided into 2 groups(0 or 0.2%FOS). The experiment lasted from day 85 of gestation to day 21 of lactation. Reproductive performance,glucose tolerance, placental angiogenesis, and intestinal flora of sows were assessed. At weaning, 192weaned piglets were grouped in 2 × 2 factorial designs, with the main effects of FOS supplemental level of sow diet(0 and 0.2%), and FOS supplemental level of weaned piglet diet(0 and 0.2%), respectively. The growth performance and diarrhea rate of the weaned piglets were analyzed during a 28-d *** dietary supplementation of FOS was shown to reduce the stillbirth and invalid piglet rates(P weaned piglets(P < 0.05) and increased the content of short-chain fatty acids in feces(P < 0.05). Furthermore, only post-wea
