Forty-eight newly weaned Angus crossbred beef steers were fed the same total mixed ration ad libitum for 42 days. On day 42, the steers were divided into two groups of lowest (LF: n = 8) and highest ADG (HF: n = 8), and blood samples were obtained from the two groups for plasma preparation. Relative quantification of carboxylic-acid-containing metabolites in the plasma samples was determined using a metabolomics technique based on chemical isotope labeling liquid chromatography mass spectrometry. Metabolites that differed (fold change (FC) \u2265 1.2 or \u2264 0.83 and FDR \u2264 0.05) between LF and HF were identified using a volcano plot. Metabolite set enrichment analysis (MSEA) of the differential metabolites was done to determine the metabolic pathways or enzymes that were potentially altered. In total, 328 metabolites were identified. Volcano plot analysis revealed 43 differentially abundant metabolites; several short chain fatty acids and ketone bodies had greater abundance in HF steers. Conversely, several long chain fatty acids were greater in LF steers. Five enzymatic pathways, such as fatty acyl CoA elongation and fatty-acid CoA ligase were altered based on MSEA. This study demonstrated that beef steers with divergent ADG had altered plasma carboxyl-metabolome, which is possibly caused by altered abundances and\/or activities of enzymes involved in fatty acid oxidation and biosynthesis in the liver.<\/jats:p>","DOI":"10.3390\/ani11010067","type":"journal-article","created":{"date-parts":[[2021,1,1]],"date-time":"2021-01-01T22:35:48Z","timestamp":1609540548000},"page":"67","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Plasma Carboxyl-Metabolome Is Associated with Average Daily Gain Divergence in Beef Steers"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3875-6156","authenticated-orcid":false,"given":"Ibukun","family":"Ogunade","sequence":"first","affiliation":[{"name":"Division of Animal and Nutritional Science, West Virginia University, Morgantown, WV 26506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9256-1280","authenticated-orcid":false,"given":"Adeoye","family":"Oyebade","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bremansu","family":"Osa-Andrews","sequence":"additional","affiliation":[{"name":"Division of Animal and Nutritional Science, West Virginia University, Morgantown, WV 26506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0216-926X","authenticated-orcid":false,"given":"Sunday","family":"Peters","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Berry College, Mount Berry, GA 30149, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1684","DOI":"10.1017\/S1751731114001463","article-title":"The relationship between feed efficiency and the circadian profile of blood plasma analytes measured in beef heifers at different physiological stages","volume":"8","author":"Gonano","year":"2014","journal-title":"Animal"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Alexandre, P.A., Kogelman, L.J.A., Santana, M.H.A., Passarelli, D., Pulz, L.H., Fantinato-Neto, P., Silva, P.L., Leme, P.R., Strefezzi, R.F., and Coutinho, L.L.
