This study aimed to assess the impact of EO blends (oregano, cinnamon and lemon oils) on growth performance, meat physicochemical parameters, intestinal health and lipid metabolism in the small intestine of weaned Bamei (a kind of obese\u2010type pig) piglets. One hundred and forty\u2010four male 60\u2010day\u2010old weaned Bamei piglets were randomly assigned to three groups of six replicates each: CON (basal diet), T1 (basal diet\u2009+\u2009250\u2009mg\/kg EO), and T2 (basal diet\u2009+\u2009500\u2009mg\/kg EO) over 28 days. The results showed that T1 trended to improve the average daily gain and feed intake to body gain ratio (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.1), reduced water loss (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), and increased the redness of meat (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) compared to the CON. In addition, a significant change in the proportion of C17:0 and C20:1 was observed in the meat of T1 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Improved intestinal health was evidenced by the reduced crypt depth, improved villi\u2010to\u2010crypt length ratio, and better superoxide dismutase activity in T1 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Further study on intestinal lipid metabolism showed that duodenal lipase activity and the mRNA expression levels of lipid transport\u2010related genes in the jejunum (FABPs, APOA1, APOB and ACSL3) were significantly reduced, alongside diminished serum lipid metabolites (Total protein and triglyceride) in the groups fed with EO (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). In short, EO supplementation especially at 250\u2009mg\/kg improved intestinal health and inhibited lipid metabolism, which had a positive effect on the overall performance of Bamei piglets. This new evidence contributes to understanding the early regulatory role of EO in obese pigs and their potential to alleviate adolescent obesity.<\/jats:p>","DOI":"10.1111\/jpn.14074","type":"journal-article","created":{"date-parts":[[2024,11,21]],"date-time":"2024-11-21T04:29:53Z","timestamp":1732163393000},"page":"574-583","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effects of Essential Oil Blends Supplementation on Growth Performance, Meat Physiochemical Parameters, Intestinal Health and Lipid Metabolism of Weaned Bamei Piglets"],"prefix":"10.1111","volume":"109","author":[{"given":"Jian","family":"Du","sequence":"first","affiliation":[{"name":"Research Centre for Livestock Environmental Control and Smart Production, College of Animal Science and Technology Nanjing Agricultural University Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqi","family":"Dai","sequence":"additional","affiliation":[{"name":"Research Centre for Livestock Environmental Control and Smart Production, College of Animal Science and Technology Nanjing Agricultural University Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cuiguang","family":"Li","sequence":"additional","affiliation":[{"name":"Research Centre for Livestock Environmental Control and Smart Production, College of Animal Science and Technology Nanjing Agricultural University Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chala","family":"Adugna","sequence":"additional","affiliation":[{"name":"Research Centre for Livestock Environmental Control and Smart Production, College of Animal Science and Technology Nanjing Agricultural University Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Analysis and Testing Center, Corporate Research Institute Nanjing Well Pharmaceutical Group Co.
