While conventional interventions, including antimicrobials, have effectively mitigated these sequelae, concerns surrounding antimicrobial resistance necessitate the exploration of alternatives. Fucoidan, derived from brown seaweed, offers promise due to its antioxidant and anti-inflammatory effects. Previous research has been limited to the in-feed supplementation of partially purified fucoidan extracted from brown seaweed. The focus of the present study is assessing the effect of a preweaning drench with highly purified (85%) fucoidan on piglet growth, immune response, and intestinal morphology post-weaning. Forty-eight male piglets at 17 \u00b1 3 days of age (5.67 \u00b1 0.16 kg) were assigned to a saline (control), fucoidan, or antimicrobial group, receiving treatment as a single 18 mL oral drench three days before weaning. Monitoring for seven days post-weaning included body weight measurements, blood sample collection for the inflammatory protein assay, and small intestine morphological analysis. The findings revealed that the preweaning fucoidan drench did not elicit adverse effects on piglets. However, neither fucoidan nor antimicrobial drenches significantly enhanced growth parameters, immune markers, or intestinal morphology compared to that of the control-treated piglets (p &gt; 0.05). The lack of response may be attributed to the high health status of the experimental cohort and the limitation of a single dosage. Future research should consider a more challenging production setting to evaluate the viability and optimal application of fucoidan as an antimicrobial alternative in the pig industry.<\/jats:p>","DOI":"10.3390\/ani14101472","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T11:31:52Z","timestamp":1715772712000},"page":"1472","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Preweaning Purified Fucoidan Drench: Effects on Growth, Immune Response, and Intestinal Morphology in Weaned Piglets"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3694-4155","authenticated-orcid":false,"given":"Bonnie","family":"Homer","sequence":"first","affiliation":[{"name":"School of Animal and Veterinary Sciences, The University of Adelaide, Roseworthy, SA 5371, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7184-0881","authenticated-orcid":false,"given":"Reza","family":"Barekatain","sequence":"additional","affiliation":[{"name":"South Australian Research and Development Institute, Roseworthy, SA 5371, Australia"},{"name":"College of Engineering and Sciences, Flinders University, Bedford Park, SA 5042, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4016-2576","authenticated-orcid":false,"given":"Kiro R.","family":"Petrovski","sequence":"additional","affiliation":[{"name":"School of Animal and Veterinary Sciences, The University of Adelaide, Roseworthy, SA 5371, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0322-7115","authenticated-orcid":false,"given":"Kate J.","family":"Plush","sequence":"additional","affiliation":[{"name":"SunPork Group, Eagle Farm, QLD 4009, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8437-0743","authenticated-orcid":false,"given":"Corinna","family":"Dwan","sequence":"additional","affiliation":[{"name":"Marinova Pty Ltd., 249 Kennedy Drive, Cambridge, TAS 7170, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darryl N.","family":"D\u2019Souza","sequence":"additional","affiliation":[{"name":"SunPork Group, Eagle Farm, QLD 4009, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul J.","family":"Verma","sequence":"additional","affiliation":[{"name":"South Australian Research and Development Institute, Roseworthy, SA 5371, Australia"},{"name":"College of Engineering and Sciences, Flinders University, Bedford Park, SA 5042, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3294-8301","authenticated-orcid":false,"given":"Roy N.","family":"Kirkwood","sequence":"additional","affiliation":[{"name":"School of Animal and Veterinary Sciences, The University of Adelaide, Roseworthy, SA 5371, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2026-2070","authenticated-orcid":false,"given":"Bryony S.","family":"Tucker","sequence":"additional","affiliation":[{"name":"South Australian Research and Development Institute, Roseworthy, SA 5371, Australia"},{"name":"College of Engineering and Sciences, Flinders University, Bedford Park, SA 5042, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1071\/AR02172","article-title":"Lifetime and post-weaning determinants of performance indices of pigs","volume":"54","author":"Dunshea","year":"2003","journal-title":"Aust.
