Materials and methods: Sows (n = 244) were allotted in a randomized complete block design to 1 of 2 vitamin supplementation levels. At weaning, 765 progeny from a subset of sows were allotted to treatments in a 2 × 2 factorial arrangement of two sow and two nursery vitamin supplementation levels with 15 pens/treatment. Performance and vitamin status of sows and progeny were measured from farrowing to nursery exit. Results: Reduced vitamin supplementation reduced sow lactation feed intake (P = .01), hepatic vitamin A (P = .001), and serum vitamin D (P < .001), but did not affect sow body weight or litter performance. Regardless of vitamin levels fed to the sow, progeny fed reduced levels post weaning had decreased circulating (P < .001) and stored (P = .03) vitamin levels and a reduction in average daily gain (P < .001), average daily feed intake (P < .001), gain:feed ratio (P = .002), and body weight (P < .001) at the end of the nursery period compared to progeny fed industry levels. Implications: Reduced vitamin supplementation reduced sow feed intake without affecting sow or litter performance, but decreased circulating and stored vitamin levels in sows could impact long-term reproductive performance. Reduced vitamin inclusion levels in nursery diets reduced performance and serum vitamin concentrations compared to industry vitamin levels.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46207608","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}

Materials and methods: Four groups of 10 market weight pigs (40 market weight pigs total) and 1 group of 10 sows were used. Each group of market weight animals received a different oral drench dose of sodium nitrite solution (1× [400-441 mg/kg], 2× [800-882 mg/kg], 2.5× [1000-1102 mg/kg], and 3× [1200-1323 mg/kg]) and was observed for distress behaviors. Two market weight animals in each treatment group were implanted with a monitor to measure body temperature, heart rate, and activity levels. The dosing rate with apparent best behavioral and physiological response was applied to the 10 sows and the same behaviors monitored. After death was confirmed, ocular fluid and skeletal muscle samples were collected from the sows. Results: An increased dosage of sodium nitrite greatly reduced the time to distress with a significant linear relationship. A higher frequency of vocalizations and the most frequent spikes in activity levels were observed in the lowest dosing group. No correlation was found between ocular fluid nitrite and skeletal muscle sodium nitrite concentrations. Implications: Oral drenching of sodium nitrite is a viable method for swine depopulation events. Higher doses of sodium nitrite have better welfare associations. Ocular fluid nitrite anion concentrations do not correlate with sodium nitrite skeletal muscle concentrations.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43511838","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}

Materials and methods: Two hundred and two sows from 5 Macedonian pig farms were clinically examined for PDS 12 to 24 hours after farrowing. Vaginal swabs for bacteriological testing were taken from PDS-affected (PDSA, n = 47) and PDS-unaffected (PDSU, n = 155) sows. In total, 74 isolates of E coli were tested by multiplex polymerase chain reaction for the presence of virulence genes related to specific pathogenic strains. Results: Genes associated with extra-intestinal pathogenic E coli (ExPEC) strains were the most prevalent among all tested E coli isolates. The most dominant gene among all E coli isolates was fimC. The iss gene was more prevalent in PDSA sows compared to PDSU sows (P = .02). Multivariable logistic regression showed that lower parity sows (P ≤ .001) and presence of the iss (P = .003) and astA genes (P = .03) were correlated with the occurrence of PDS. Implications: Lower parity sows vaginally infected with E coli associated with particular ExPEC strains are at higher risk of developing PDS. Positive vaginal swabs for E coli and iss gene found early after farrowing were associated with PDS in sows. Classification of E coli into specific ExPEC pathotype was not possible by virulence genotyping only.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48216667","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}
