Actinobacillus pleuropneumoniae serotype 15 was identified as the causative agent of the clinical disease. Given that A pleuropneumoniae serotype 15 has been infrequently diagnosed in the United States, an outbreak investigation was conducted to explore biosecurity hazards and epidemiological aspects associated with the surge of cases. The investigations revealed that all farms had significant gaps in biosecurity and relied heavily on third-party service providers, which may have contributed to the pathogen spread.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":"7 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139458339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most severe problems occur when a pig is rehydrated with unfettered water access. The high concentration of sodium in the brain draws water in and the brain swells inside the rigid calvarium causing neurologic clinical signs and ultimately, death. Rehydration must occur as a slow process over a period of many hours to prevent brain swelling. Water introduction must occur over a period of hours with slow water introduction to allow for the sodium ion exchange.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":"10 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135371871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analyses demonstrated a genetically close relationship with SVA isolates from the United States detected in 2017, sharing a 98.3% to 98.4% nucleotide identity.

Materials and methods: Heads from 64 market-age pigs (32 barrows and 32 gilts) were collected from a federally inspected slaughter facility. Heads were randomly assigned to one of 4 caliber and ammunition combinations: .22 long rifle (LR), .22 Magnum (Mag), .38 Special, and 9 mm. The fully jacketed ammunition was discharged from each of the 4 unique firearms (each with a 16-in barrel length) while ensuring a consistent muzzle to forehead distance of 12.7 cm. Results: The 9 mm bullets traveled further through the head and into the ballistic gel (P < .001) and the furthest total distance (P < .001). Bullets from the .38 Special traveled further into the ballistic gel and a further total distance than both the .22 LR and .22 Mag (P < .001). The trauma area of the brain was greater for the 9 mm and the .38 Special bullets when compared to .22 LR or .22 Mag, respectively (P < .001). There was no difference in the trauma area of the brain for the .22 LR bullets compared to .22 Mag bullets (P = .12). Implications: This proof-of-concept study generated data to define efficacy and safety considerations when using a firearm to euthanize market-weight pigs and demonstrated that the .22 LR full metal jacket bullet could provide predictable euthanasia in market-weight pigs with minimal risk of contralateral emergence.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":"16 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
