This study evaluated cow\u2013calf vitamin A status under restricted maternal vitamin A intake during late gestation and early lactation. Beef cows (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009114) were individually fed 14,000 or 29,000\u2009IU\/d of vitamin A (approximately 30% or 75% of recommendations) from 128 days pre\u2010calving to 32 days post\u2010calving. All cows began with high liver retinol concentrations (mean \u00b1 SD: 786\u2009\u00b1\u2009252\u2009\u03bcg\/g DM) from prior grazing. Cow liver and plasma, and calf liver and plasma, were sampled 32\u2009\u00b1\u20097 days postpartum. Cow liver retinol declined to 483\u2009\u00b1\u2009182\u2009\u03bcg\/g DM by 32 days postpartum. Calf liver retinol averaged 51\u2009\u00b1\u200927\u2009\u03bcg\/g DM and plasma retinol 190\u2009\u00b1\u200947\u2009ng\/mL, both below adequacy thresholds. Calf plasma retinol increased with calf liver retinol (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01;\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.22). Maternal post\u2010calving liver retinol explained 9.5% of the variation in calf liver retinol. These results indicate that adequate maternal liver vitamin A stores at calving do not ensure adequate calf vitamin A status when maternal dietary vitamin A is restricted.\n                  <\/jats:p>","DOI":"10.1111\/asj.70175","type":"journal-article","created":{"date-parts":[[2026,4,11]],"date-time":"2026-04-11T05:39:48Z","timestamp":1775885988000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Maternal Liver Retinol Stores Do Not Ensure Adequate Calf Vitamin A Under Restricted Late\u2010Gestation Vitamin A Intake"],"prefix":"10.1111","volume":"97","author":[{"given":"Hannah\u00a0F.","family":"Speer","sequence":"first","affiliation":[{"name":"University of Nebraska\u2010Lincoln  Lincoln Nebraska USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harvey\u00a0C.","family":"Freetly","sequence":"additional","affiliation":[{"name":"USDA, ARS, US Meat Animal Research Center, Clay Center  Nebraska USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary\u00a0E.","family":"Drewnoski","sequence":"additional","affiliation":[{"name":"University of Nebraska\u2010Lincoln  Lincoln Nebraska USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,10]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Official Methods of Analysis","author":"AOAC","year":"2011"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.2218545"},{"key":"e_1_2_8_4_1","first-page":"142","article-title":"Vitamin A Transfer From Cows to Calves","volume":"43","author":"Branstetter R.
