Improving sow health during the perinatal period is crucial for reproductive performance. Cinnamaldehyde (CA), a naturally occurring compound, is known for its anti-inflammatory, antioxidant, and gut microbiota-modulating properties. This study evaluated the effects of dietary CA supplementation during the perinatal period on reproductive performance, milk composition, redox status, and gut microbiota of sows. Forty DanBred sows were randomly divided into two groups and fed either a basal (CON) diet or the basal diet supplemented with 1 g/kg CA from day 107 of gestation to day 7 of lactation. The results showed that dietary CA supplementation decreased farrowing duration (−78 min, P = 0.031) and tended to increase the concentrations of crude fat ( P = 0.070) and dry matter ( P = 0.078) in colostrum. Additionally, CA increased plasma glucose ( P = 0.012) and decreased non-esterified fatty acid (NEFA) and triglyceride (TG) concentrations ( P < 0.05) at farrowing. CA also reduced malondialdehyde (MDA) concentration ( P = 0.048) and tended to increase plasma total superoxide dismutase activity ( P = 0.084) at farrowing. Furthermore, CA supplementation increased the average daily gain (ADG) of piglets during days 15 to 21 of lactation ( P = 0.040) and tended to increase the average daily feed intake (ADFI) of sows during days 8 to 14 of lactation ( P = 0.059). Gut microbiota analysis revealed that CA increased the relative abundances of g_Roseburia , s_Ruminococcus_flavefaciens , ...
