Figure 4From: Plasma metabolomic profiles and immune responses of piglets after weaning and challenge with E. coliPCA scores plots of pig plasma collected on day 0, 4, and 11 postweaning. The PCA model shows a clear separation of the data according to the days postweaning. The piglets were weaned on day 0 and challenged with E. coli F18 on day 1, 2, and 3 postweaning. Plasma was collected on day 0 before the piglets were moved to the nursery pen.Back to article page
