Does providing high vitamin diets in gestation improve performance and passive immunity?

Hannah Burlet, Frederic Beaudoin, Beatrice Sauve, Laetitia Cloutier, Matheus Costa, Danyel Bueno Dalto – While studies have looked at increasing a subset of vitamins during gestation, no published works have looked at increasing the concentrations of all vitamins normally included in vitamin premixes. This study set out to examine how a high vitamin diet, containing concentrations of all vitamins beyond industry standards and fed from insemination until the day of farrowing in two consecutive cycles, would perform relative to diets a control diet formulated to NRC (2012) recommendations.

The results showed no consistent differences between the control and high vitamin diets in any measures assessed. In this context, vitamin supplementation beyond industry standard did not provide any consistent advantage over supplementation at NRC 2012 standards, which are below what is normally fed.
