In recent years, there has been an increase in the number of articles published related to microbiome studies in swine. With respect to sows, microbiome studies mainly focused on the gut, with some studies evaluating the reproductive tract and mammary microbiome. However, studies about urinary microbiome are still lacking. The present literature indicates that the microbiome in the sow’s gut can affect the microbiome in other body parts. Moreover, the understanding of the dynamics and interactions among microbial populations within the sow or the herd has led to improvements in animal health and reproductive performance. This review provides new insights related to sow intestinal, urinary, mammary, and reproductive microbiomes and their relationships with reproductive outcomes, diseases, and early colonization in offspring by gathering the most recent work in this field as well as pinpoints information gaps that require further investigation. This literature review also sheds light on the knowledge regarding the role of microbiomes in the reduction of antimicrobial use.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45090686","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: Pigs were vaccinated with either Fostera PRRS (n = 52), Prevacent PRRS (n = 50), or sterile water (nonvaccinated; n = 47). Four weeks after vaccination, all animals were challenged with PRRSV-2 lineage 1 ORF5 RFLP 1-7-4. Viremia was determined at 3-, 6-, and 12-days post challenge. Body weights were recorded to determine ADG throughout the experiment. Percentage lung lesions were assessed on day 40 (12 days post challenge). Results: Vaccination with either vaccine reduced (P < .001) lung lesions, increased (P < .001) ADG post challenge, and better controlled viremia (P < .001) compared to nonvaccinated pigs.

Materials and methods: Retrospective production records and information on housing methods were collected from 23 farms using pen gestation and analyzed for the removal of 214,254 sows from 2014 through 2020. Statistical analyses were performed to evaluate differences in longevity, productivity, and the impact of housing methods. Results: Lameness was the third most reported cause of removal for sows in the study (13.7%). Sows culled for lameness spent significantly fewer days in the herd (P < .001), resulting in fewer litters (P < .001). The odds of removal for lameness were increased by several farm level factors including using dynamic groups and decreasing square footage (P < .05). Implications: Lameness is one of the top 3 reasons reported for sow removal and those sows are costly as they leave the herd earlier, are less productive, and are more likely to die or be euthanized versus culled. Housing methods play a role in the odds of removal for lameness and should be further investigated.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43769746","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: Pigs were allocated to a 3 × 2 factorial arrangement of treatments (4 pens/treatment combination, 3 pigs/pen) with factors being intramuscular iron (200 mg at birth; 100 mg at birth and weaning [22.4 days of age]; or 100 mg at birth and 14 days of age) and dietary copper (14 [control] or 250 ppm [supplemented]). Blood was sampled at days 0, 7, and 49 post weaning. Results: Pigs receiving 100 mg iron at birth and weaning, but not pigs in the other groups, had hemoglobin concentrations consistent with iron deficiency at day 0 (iron treatment × day, P < .001). For pigs receiving 100 mg iron at birth and 14 days of age, hepcidin concentrations were greater in control pigs than copper-supplemented pigs (iron treatment × diet, P = .06). A diet × day interaction (P = .07) existed for hepcidin, with concentrations greater in control vs copper-supplemented pigs on day 49. Pigs receiving iron at day 14 of age had the greatest (P = .01) weaning weights. Gain from day 0 to 7 was enhanced (P = .03) by 250 ppm copper but nursery performance (day 0-49) was unaffected by iron treatment. Implications: Pigs receiving 100 mg iron at birth were iron deficient at weaning. Treatment with iron at 14 days of age could improve weaning weights and prevent iron deficiency at weaning. Age-related increases in hepcidin were decreased by additional copper supplementation.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45943403","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: In vitro broth microdilution susceptibility testing for minimal inhibitory concentration values were performed using ten antimicrobial agents (ampicillin, ceftiofur, danofloxacin, enrofloxacin, florfenicol, penicillin, tetracycline, tilmicosin, trimethoprim-sulfamethoxazole, and tulathromycin) with A pleuropneumoniae (n = 250), B bronchiseptica (n = 602), P multocida (n = 874), and S suis (n = 1223) following methods and susceptibility breakpoints approved by the Clinical and Laboratory Standards Institute. Results: Actinobacillus pleuropneumoniae isolates were 100% susceptible to ceftiofur, florfenicol, and tulathromycin and P multocida isolates were 100% susceptible to ceftiofur. High rates of susceptibility (95% to > 99%) were observed for A pleuropneumoniae to tilmicosin; for P multocida to ampicillin, enrofloxacin, florfenicol, penicillin, tilmicosin, and tulathromycin; for S suis to ampicillin and florfenicol; and for B bronchiseptica to tulathromycin. Tetracycline exhibited low susceptibility rates against A pleuropneumoniae (0% to 10.6%), P multocida (23.2% to 38.2%), and S suis (0.8% to 2.1%). No susceptibility of B bronchiseptica to ampicillin (0%) and low rates of susceptibility to florfenicol (3.9% to 15.2%) were also observed. Implications: Under the conditions of this study, the predominant pathogens associated with swine respiratory disease in the United States and Canada, A pleuropneumoniae, B bronchiseptica, P multocida, and S suis collected during 2016 to 2020, display high rates of susceptibility to most veterinary antimicrobial agents.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45364579","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}
