Treatments were MCFA supplementation levels at 0.0%, 0.4%, 0.8%, 1.2%, and 1.6%. The 2% soybean oil in the basal diet was replaced with MCFA (a 50:50 blend of free caproic and caprylic acids) on a weight-to-weight basis.</p><p><strong>Results: </strong>Increasing MCFA levels tended to linearly increase the final body weight (p = 0.06) and average daily gain in the overall period (p = 0.06), with no difference in overall average daily feed intake. The gain-to-feed ratio increased linearly in d 7-14 (p = 0.06, tendency) and 14-21 postweaning (p<0.05). Fecal score linearly decreased in d 0-7, 7-14, and 14-21 (p<0.05) postweaning, resulting in a linear reduction in the overall period (p<0.05). Plasma malondialdehyde levels at d 28 postweaning showed a quadratic decrease with increasing MCFA levels with the lowest value at 0.8% (p<0.05). Plasma free fatty acid levels at d 14 postweaning linearly decreased with increasing MCFA levels (p<0.05). Fecal total short-chain fatty acid (SCFA) concentrations tended to be lower (p = 0.09, tendency) in the MCFA treatments (0.4%-1.6%) than the control treatment (0.0%). There were no differences in plasma superoxide dismutase activity and fecal ammonia concentrations among dietary treatments.</p><p><strong>Conclusion: </strong>Increasing MCFA supplementation levels up to 1.6% could improve growth rate, feed efficiency, and fecal consistency without affecting feed intake and have the potential to reduce oxidative stress and free fatty acid levels in weaning pigs, while fecal SCFA concentrations could be slightly reduced by MCFA supplementation.</p>","PeriodicalId":7825,"journal":{"name":"Animal Bioscience","volume":" ","pages":"2173-2184"},"PeriodicalIF":2.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12415358/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
