Popis: The aim of our study was to describe the effect of stray voltages lower than 0.5 V on inflammation and oxidative status biomarkers in weaned piglets. The study was conducted on a nursery barn with two rooms of 12 pens of 38 28-day old piglets each, on two batches in France. In each pen, stray voltages were measured for each drinker and feeder every two weeks (9, 23, 37 and 50 days after inclusion). On the same days, two cotton ropes per pen were suspended for 30 min in order to collect oral fluid for salivary cortisol dosage. Two pigs per pen (84 pigs in total) were randomly selected at inclusion and blood sampled on days 9, 30 and 50 after weaning for the dosage of haptoglobin, hydroperoxides (HPO), and blood antioxidant potential (BAP). Pens were allocated to 4 groups based on their voltage levels in drinkers and feeders, with high (HVD, >125 mV) or low (LVD, 50 mV) and low (LVF
