Effect of chronic enteral Fusarium toxin deoxynivalenol (DON) exposure and pre- or post-hepatic E. coli lipopolysaccharide (LPS) infusion on arterial, jugular or portal blood lactate in pigs. Reference: 0.84 ± 0.24 mmol/L in venous blood [28]. Barrows were either fed a DON contaminated ration (4.59 mg/kg feed) or control feed during 29 days. Infusion groups were divided as follows: pre-hepatic LPS infusion (CON_CONjugular-LPSportal, n = 7 and DON_CONjugular-LPSportal, n = 6), post-hepatic LPS infusion (CON_LPSjugular-CONportal, n = 8 and DON_LPSjugular-CONportal, n = 6), and control infusion (CON_CONjugular-CONportal, n = 7 and DON_CONjugular-CONportal, n = 7). Infusion from time 0 until 60 min with 7.5 µg LPS/kg BW in 0.9% saline. Feed was offered during 15 min prior to infusion start. LSMeans. PSEM = 0.56. Significance: Group (G): p ≤ 0.001; Catheter (C): p = 0.78; Time (T): p ≤ 0.001; G × C × T: p ≤ 0.001. Table illustrates differences between DON and CON fed post-hepatic LPS infused groups at different times. T = trend (p ≤ 0.10).
