Effects of dietary acetaminophen and Vitamin C supplement on serum cortisol and tumor necrosis factor-alpha concentrations in pigs vaccinated with foot-and-mouth disease vaccine

Abstract

This study evaluated the effect of a combination of acetaminophen and vitamin C (CAV) on reducing serum cortisol and tumor necrosis factor-a (TNF-a) concentrations in piglets vaccinated with foot-and-mouth disease (FMD) vaccine. Piglets were vaccinated with FMD vaccine and treated with CAV at concentrations of 0.0, 0.5, 1.0, and 2.0 kg/ton feed (P-CON, AD-1, AD-2, and AD-3, groups, respectively) for 5 days post-vaccination. Cortisol and TNF-a levels at 5 days post-treatment in the AD-1?3 groups were significantly lower than that in the P-CON group (p < 0.05). There were no significant differences between AD-2 and AD-3 groups and non-vaccinated, non-CAV-treated piglets.
