Materials and methods: A total of 70 pregnant gilts were enrolled and allocated into 4 groups. Group 1 was given NPE at 5, 4, and 3 weeks prefarrowing (WPF); Group 2 at 5 and 3 WPF; and Group 3 at 5 WPF only. Group 4 (control group) did not receive any NPE. Samples from 46 gilts and litters (5 piglets/litter) were tested at 12 sample times. Piglets were sampled weekly from 24 hours of age until 6 weeks of age and tested by quantitative reverse transcriptase-polymerase chain reaction for RVA, RVB, and RVC. Results: There was a significant improvement in weaning weight of piglets born to gilts that received 3 NPE administrations compared to fewer or no NPE administrations. Shedding of RVA and RVB from piglets were well controlled in the farrowing room regardless of treatment group, but RVC was observed as early as 1 week old. This study was conducted on a single farm, and the results should be carefully interpreted with knowledge of variations in farms and systems. Implications: Three administrations of NPE to gilts prefarrowing had valuable production and economic benefits for the producer. Circulation patterns of RVA, RVB, and RVC appear to correlate; interventions for one have value against the others.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49214925","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: Prospective, observational cohort studies of the water use patterns within each day were conducted in 5 pig buildings using either a turbine or ultrasonic water flow meter attached to the main water pipe entering each building. Water use data were collected from multiple batches of pigs (second-stage weaners over eleven 48-day periods and grower-finishers over 4 periods of 21-43 days). Semi-parametric models of pig water use patterns within each day were estimated using the brms software package in R. To estimate the interacting effects of time and pig body weight on water use by pigs, we used tensor product smooths for time and pig body weight. Results: The water use pattern within each day varied between the cohorts, and the pattern of many cohorts changed as the pigs gained weight. Some patterns were unimodal and others were bimodal, with the main peak in water use occurring early afternoon to late afternoon. Implications: Water use patterns of pigs within each day varied between and within cohorts. The water use pattern of one cohort cannot be used reliably to predict that of other cohorts, even if they are reared in the same building. Water use pattern data may be valuable for optimizing in-water antimicrobial dosing regimens.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41537405","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: Eighteen commercial crossbred pigs received an epidural to induce a nonambulatory state. The HMH sked rescue system, revised deer sled, and ice fishing sled were tested as handling tools by 2 employees for time to place and move the pig, pig vocalization and struggle scores, and tool durability. Results: Time to place the nonambulatory pig from the start pen floor onto the handling tool, time to secure the nonambulatory pig on the handling tool, and total time were not affected by the handling tool (P ≥ .12). There was a trend for time to move the handling tool with the nonambulatory pig from the start to end pen, which included removing the pig from the handling tool and placing them onto the end pen floor (P = .06). The ice fishing sled was the most durable with no creases, rips, or holes. There were no handling tool differences for pig vocalization or struggle scores (P > .10). Changes in pig respiration rate and pig body temperature did not differ between handling tools (P ≥ .71). Implications: Under study conditions, the sked, revised deer sled, and ice fishing sled were all humane tools to move nonambulatory grow-finish pigs. Caretakers need to evaluate the best choice for their farm.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42287573","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}

Brockmeier","doi":"10.54846/jshap/1298","DOIUrl":"https://doi.org/10.54846/jshap/1298","url":null,"abstract":"Objective: Introduction of Streptococcus equi subspecies zooepidemicus strains into naive populations results in field mortality rates of 30% to 50% over 5 to 10 days. Because of the rapid disease progression, our goal was to determine whether antibiotic intervention could control S zooepidemicus disease in a group of animals following development of clinical signs. Materials and methods: Thirty-two pigs were challenged with S equi subsp zooepidemicus. Following the development of clinical signs, 16 were treated with long-acting, injectable ceftiofur. Seven unchallenged pigs served as controls. Clinical signs were monitored following challenge and survival was compared between groups. Antibody titers were measured on day 0 and day 30 post challenge. On day 30 post challenge, 3 contact pigs were commingled with 2 treated animals to evaluate S equi subsp zooepidemicus transmission. Results: Ceftiofur treatment eliminated clinical signs in 15 of 16 animals. However, multiple treatments were required to control disease in treated animals (2-3 doses providing 12-18 days of coverage). Antibody titers to S equi subsp zooepidemicus increased in challenged animals treated with ceftiofur, indicating sufficient exposure for immune stimulation. No contact pigs developed clinical signs of S equi subsp zooepidemicus following exposure. Implication: Rapid application of injectable antibiotics is a viable method to reduce losses due to the introduction of S equi subsp zooepidemicus into a naive group of pigs and may help prevent transmission to contact animals following recovery.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47467243","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: Forty-eight healthy pigs of different stages of production were used for sampling of different tissues. Seven sows and a minimum of 10 animals from each phase of production (suckling, nursery, and finishing) were selected for sampling. A blood sample was collected via sterile venipuncture for serum vitamin and mineral analysis. After euthanasia, the diaphragm and liver were collected. Samples were submitted to the Iowa State University Veterinary Diagnostic Laboratory for analysis. Data were analyzed using SAS (version 9.4; SAS Institute Inc) and presented as minimum and maximum concentrations with standard error. The experimental unit was the animal. Results: Levels of vitamin A, vitamin E, copper, zinc, selenium, iron, and manganese were higher in liver tissues than in serum and diaphragm tissues. Diaphragm muscle had similar levels of phosphorus as the liver tissue. Serum had similar levels of calcium as the liver tissue. Implications: These data provide a sampling of vitamin and mineral levels present in tissues and serum of commercial pigs and suggests that vitamin and mineral levels differ between sampling sites.","PeriodicalId":17095,"journal":{"name":"Journal of Swine Health and Production","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46668809","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}
