This study aimed to evaluate AAB as an animal-based indicator of electrical stunning ineffectiveness, which could be used by official veterinarians during the post-mortem inspection of pigs. Information on 3584 finishing pigs was collected at a Portuguese abattoir that performs head-to-body electrical stunning with horizontal bleeding. Of them, 15.5% of the pigs presented signs of ineffective stunning. AAB lung lesions were found in 27.8% of lungs. Despite what was predicted, a strong correlation was found between well stunned animals and the presence of blood lesions in lungs (p = 0.006). Statistical significances were found between pigs\u2019 lateral recumbency at the conveyor and the presence of blood affecting one lung. Under the conditions of this study, the authors cannot point to AAB lung lesions as an animal-based indicator of electrical stunning ineffectiveness. Further studies should be conducted to establish a better understanding of the causes of aspiration of blood, in particular how horizontal bleeding may affect the occurrence of similar lesions.<\/jats:p>","DOI":"10.3390\/ani13142292","type":"journal-article","created":{"date-parts":[[2023,7,14]],"date-time":"2023-07-14T00:39:41Z","timestamp":1689295181000},"page":"2292","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Agonic Aspiration of Blood: Not Useful as an Animal-Based Indicator of Electrical Stunning Ineffectiveness in Pigs (Sus scrofa domesticus)"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0495-2135","authenticated-orcid":false,"given":"Maria Francisca","family":"Ferreira","sequence":"first","affiliation":[{"name":"School of Agrarian and Veterinary Sciences (ECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1877-8254","authenticated-orcid":false,"given":"Emma","family":"F\u00e0brega","sequence":"additional","affiliation":[{"name":"Animal Welfare Program, IRTA, 17121 Monells, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6330-4560","authenticated-orcid":false,"given":"Isabel","family":"Pires","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5001-801 Vila Real, Portugal"},{"name":"CECAV\u2014Veterinary and Animal Research Centre, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5001-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8588-7071","authenticated-orcid":false,"given":"Maria Madalena","family":"Vieira-Pinto","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5001-801 Vila Real, Portugal"},{"name":"CECAV\u2014Veterinary and Animal Research Centre, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5001-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5001-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,13]]},"reference":[{"unstructured":"European Commission (2022, May 10).
