The current study aimed to report the baseline amino acid (AA) profiles and blood gas concentrations in newborn, Merino single and twin lambs. From 120\u2009days of gestation, 50 single\u2010bearing and 50 twin\u2010bearing, naturally mated Merino ewes were monitored for signs of approaching parturition. At birth, blood samples of the progeny were collected, and birth weight, rectal temperature, and meconium score were recorded. Blood plasma samples were analysed for AA profiles and blood gas concentrations were determined using an i\u2010Stat Alinity. Single\u2010born lambs had a higher birth weight (5.05\u2009kg) compared to twins (4.24\u2009kg;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05). Birth rank also affected rectal temperature and AAs aspartic acid, isoleucine, leucine, and phenylalanine, all being lower in twins compared to singles (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05). These baseline data provide insight into the physiological differences between single and twin lambs at birth from dams where there has been no treatment or intervention imposed.\n                  <\/jats:p>","DOI":"10.1111\/asj.70107","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T03:45:34Z","timestamp":1757562334000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluating Amino Acid Profiles and Blood Gas Concentrations Between Single and Twin Merino Newborn Lambs"],"prefix":"10.1111","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9019-6470","authenticated-orcid":false,"given":"Leesa\u2010Joy","family":"Dunstan","sequence":"first","affiliation":[{"name":"Davies Livestock Research Centre, School of Animal and Veterinary Sciences The University of Adelaide  Roseworthy South Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle\u00a0L.","family":"Hebart","sequence":"additional","affiliation":[{"name":"Davies Livestock Research Centre, School of Animal and Veterinary Sciences The University of Adelaide  Roseworthy South Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Forbes\u00a0D.","family":"Brien","sequence":"additional","affiliation":[{"name":"Davies Livestock Research Centre, School of Animal and Veterinary Sciences The University of Adelaide  Roseworthy South Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sue\u00a0A.","family":"McCoard","sequence":"additional","affiliation":[{"name":"AgResearch Grasslands  Palmerston North New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6997-2391","authenticated-orcid":false,"given":"Mariana","family":"Caetano","sequence":"additional","affiliation":[{"name":"Davies Livestock Research Centre, School of Animal and Veterinary Sciences The University of Adelaide  Roseworthy South Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0301\u20106226(98)00192\u20104"},{"key":"e_1_2_10_3_1","first-page":"428","article-title":"Maternal Amino Acid Supplementation for Intrauterine Growth Restriction","volume":"3","author":"Brown L.
