Increasing evidence supports the benefits of improving sow nutrition during gestation and lactation to promote gastrointestinal development and overall health of piglets. The objective of this research was to investigate the effects of maternal live yeast (LY) supplementation to sows during late gestation and lactation periods on the intestinal health of suckling and weaned piglets. Sows were fed LY during gestation and lactation and piglets were killed for sampling at different time points to track the temporal effect of maternal LY supplementation on changes in markers of intestinal health and development on postnatal days 0, 10, and 18, and postweaning days 7 and 14. Results showed that maternal LY supplementation affected several markers of health and development in the offspring, especially the expression of tight junction proteins, inflammatory cytokines, and antioxidant enzymes. These results indicate that nutritional intervention during gestation and lactation could serve as an effective strategy for raising piglets with better health and growth performance.
