“…Lastly, long fasting periods and chronic hunger, together with environmental thermal variations and disease outbreaks, may lead to gastric ulcerations [ 63 , 64 ]. The prevalence of gastric ulcers at slaughterhouses can vary between 32% and 65% [ 64 ], but this figure may be underestimated, as ulcers are often subclinical. Other risk factors for gastric ulcerations include feed particle size, gastric microbiota composition, hormonal changes, Helicobacer suis infections, and low birth weight [ 64 , 65 , 66 ].…”

Preventative measures, such as biosecurity and vaccinations, are essential but not sufficient to ensure high standards of health in pig production systems. Restrictive, barren housing and many widely used management practices that cause pain and stress predispose high-performance pigs reared in intensive systems to disease. In this context, antibiotics are used as part of the infrastructure that sustains health and high levels of production in pig farms. Antimicrobial resistance (AMR) is a global emergency affecting human and animal health, and the use of antibiotics (AMU) in intensive livestock farming is considered an important risk factor for the emergence and spread of resistant bacteria from animals to humans. Tackling the issue of AMR demands profound changes in AMU, e.g., reducing their use for prophylaxis and ending it for growth promotion. In support of such recommendations, we revise the link between animal welfare and AMU and argue that it is crucial to sustainably reduce AMU while ensuring that pigs can live happy lives. In support of such recommendations, we aimed to revise the link between animal welfare and AMU in pigs by analysing stress factors related to housing and management and their impact on pig welfare. In particular, we reviewed critical management practices that increase stress and, therefore, pigs’ susceptibility to disease and reduce the quality of life of pigs. We also reviewed some alternatives that can be adopted in pig farms to improve animal welfare and that go beyond the reduction in stress. By minimising environmental and management stressors, pigs can become more immunocompetent and prepared to overcome pathogenic challenges. This outcome can contribute to reducing AMU and the risk of AMR while simultaneously improving the quality of life of pigs and, ultimately, maintaining the pig industry’s social license.

“…As the aetiology of stomach ulcers in pigs is not conclusively known, 36,48 it is difficult to give specific reasons for this lack of improvement. As an intensive grinding of the components of commercial pig feeds is considered an important contributing factor to pig stomach ulcers, 3,4,16,34,35 one reason for this could be that particle size in commercial pig feed is generally to small and not ideal.…”

“…A similar wave-like pattern of score prevalence, although not evident in the previous Swiss study, 46 was detected in two studies in Denmark. 36,43 While detailed differences between scoring systems and scoring habits may partially explain discrepancies between individual studies, this does not depreciate the value of comparing the prevalence of roughly categorized states (healthy, mild-severe scores) between countries and time points. More detailed studies on the time course of, and influence factors on gastric ulcer development, would be welcome.…”

The development of gastric ulcers in pigs has various reasons. In Switzerland, the last survey on the prevalence of gastric ulcers and possible risk factors was performed in 2005. We aimed to reassess gastric ulcers prevalence today, in 2021. A total of 1005 stomachs from fattening pigs from 136 batches and around 87 herds were evaluated at a Swiss abattoir. The Pars oesophagea of the stomach was scored from 0=healthy to 10=severe ulceration and strictures. Scores were compared between pigs produced under the labels "Integrierte Produktion Schweiz" (IPS, n=242 stomachs, 18 farms) and "Qualitätsmanagement-Schweizerfleisch" (QM, n=649, 58 farms) and others (n=114). The results showed a prevalence of 27.2% mild mucosal changes (Scores 1-3), 14.9% moderate mucosal changes (Scores 4-6) and 19.1% severe mucosal changes (Scores 7-10). Only 38.8% of the stomachs were rated 0 and thus considered healthy. Compared to the results from 2005, there is no difference concerning the lowest scores (0-2) and the highest scores (9-10). However, there was a shift from the medium scores (3-4) to higher scores (5-8). Stomach scores turned out to be herd specific. There were differences (p < 0.01) between labels, indicating that IPS pigs had less affected stomachs. Stomachs that were empty at slaughter showed higher scores (p < 0.001). The mean carcass weight of the pigs in the slaughter groups was negatively correlated (p < 0.05) to their median stomach score. Confiscations were not related to stomach scores. The results suggest that pig stomach health has not improved since 2005. The differences between labels seem to have resulted from different regulations prescribing a minimum particle size of enrichment material in IPS. The reasons for gastric ulcer development, including those on the individual herd within label, still have to be further clarified in order to allow targeted countermeasures. Given apparent farm-specificity, scoring of a limited number of stomachs per farm during the slaughter process could facilitate to establish a feedback scheme.
