BackgroundNutritional metabolism greatly influences the embryonic development and pregnancy outcomes. Exploring the metabolic differences between high and low fertility individuals plays pivotal roles in improving reproduction in mammals.ObjectiveThe objective of this study was to explore and confirm the important metabolites influencing the reproductive potential of multiparous sows.MethodsForty serum samples were collected from Landrace × Large White crossbred sows (3–5 parity) with high li...
