“…During the early post-weaning period, the higher the increases in blood HPO and haptoglobin concentrations, the higher the PEN score at the end of the period, which appears coherent. An increase in haptoglobin during that period would indicate an increase in the inflammatory level of the pigs, and oxidative stress can also result from inflammatory situations [28]. However, during the late post-weaning period, PEN occurrence and severity was decreasing particularly in the second batch and all the more in one room without any treatment or change in management practices.…”

Background Porcine ear necrosis (PEN) is a worldwide health issue and its aetiology is still unclear. The aim of this study was to describe the prevalence and the severity of PEN in a commercial farm, associated with pig behaviour and health biomarkers measures. On two consecutive batches, PEN prevalence was determined at the pen level. PEN scores, blood haptoglobin concentration and oxidative status were measured on two pigs per pen (n = 48 pens) 9, 30 and 50 days (D) after arrival to the post-weaning unit. Social nosing, oral manipulation and aggression of pen mates and exploration of enrichment materials were observed on two to three pigs per pen twice a week from D9 to D50. Results At the pen level, the higher the time spent nosing pen mates, the lower the percentage of pigs affected by PEN during both the early and the late post-weaning periods (P < 0.002) and, in the opposite, the higher the time spent orally manipulating pen mates during the late post-weaning period, the higher the percentage of affected pigs (P = 0.03). At the pig level, the higher the increase in hydroperoxides and haptoglobin during the early post-weaning period, the higher the PEN scores on D30 (P < 0.001). Conclusions This study suggests that a high incidence of social nosing, which can be an indicator of good social cohesion in a group, was significantly associated with less frequent lesions of PEN. In opposite, high incidence of oral manipulation of pen mates may increase the percentage of PEN-affected pigs. According to these observations, PEN is a multifactorial condition which may have social causes among others.

“…The animal capacity to mitigate oxidative stress is critical for the maintenance of egg production and hens’ health, especially in the prepeak period of laying, which can have long-lasting beneficial effects across the production period ( Finkel and Holbrook, 2000 ; Eid et al, 2021 ; Durand et al, 2022 ). Furthermore, it has been recently shown that the PP inclusion used in this work resulted in a consistent expression increase of cytoprotective genes and improved intestinal total antioxidant capacity ( TAC ), as well as an enhanced liver, breast meat and thigh meat TAC in broilers ( Mountzouris et al, 2019 , 2020 ).…”

“…It has even been established that any (environmental) stressor which induces dysfunction of the gut barrier will trigger inflammation ( Lambert, 2009 ). Most of these stressors will cause oxidative stress to the intestinal epithelial cells ( Durand et al., 2022 ). One such stressor which is of particular importance in poultry production is heat stress ( Ahmad et al., 2022 ).…”
