Concentrations of cytokines IL-6, TNF-α, and IL-1β from media containing whole blood and subjected to ex vivo lipopolysaccharide (LPS) or PBS treatment (Trt). Whole blood was collected on day of weaning (day 0) and 1 d postweaning from pigs receiving a corn-soybean meal based diet supplemented with 1% protected fish oil (1% PFO, n = 16 pigs; Gromega, JBS United Inc., Sheridan, IN) or no supplement (0% PFO, n = 16 pigs) 1 wk prior to farrowing until day of weaning (31 ± 2 d of age). ^a–dMeans ± SEM with different letters within measured cytokine differ.
