Fig. 3From: Acetylsalicylic acid supplementation improves protein utilization efficiency while vitamin E supplementation reduces markers of the inflammatory response in weaned pigs challenged with enterotoxigenic E. coli Effect of acetylsalicylic acid (125 ppm) on plasma urea contents after weaning. The numbers of replications were 32 individual pigs up to d 10 and were 24 pigs from d 14 to 21. All pigs were experimentally infected with an enterotoxigenic strain of E. coli on d 7 (after blood sampling), 8 and 9. ***P < 0.001, †P < 0.10Back to article page
