Steers (n = 239; 128\u00a0\u00b1\u00a014 d of age) were assigned to a 56-d weaning treatment: drylot weaning (D) or pasture weaning (P). Pasture steers grazed mature, native tallgrass range (89.2% dry matter [DM], 9.08% crude protein [CP]), without supplementation. A concentrate-based diet (18.7% CP and 1.15 Mcal NEg\/kg) was fed to D steers. Later, all steers were transitioned to a receiving, then a finishing diet and fed to a common endpoint. Body weight (BW) after and average daily gain (ADG) during weaning were greater (P &amp;lt; 0.01) for D than for P. Incidence of undifferentiated fever during weaning tended to be greater (P = 0.10) for D steers than for P steers. Conversely, incidence of keratoconjunctivitis was greater (P &amp;lt; 0.01) for P than for D during weaning (40.2% vs. 0%, respectively) and receiving (P &amp;lt; 0.01; 14.3% vs. 1.6%, respectively). At the start and end of receiving, D steers had greater (P &amp;lt; 0.01) BW compared with P steers. Drylot steers had greater (P = 0.03) ADG compared with P steers during receiving. Pasture steers tended to have greater dry matter intake (DMI) (P = 0.09) during receiving than D steers. In contrast, gain:feed (G:F) was improved (P &amp;lt; 0.01) for P steers than for D steers during receiving. Incidence of undifferentiated fever was not different (P = 0.99) between D and P steers during receiving. At start of finishing, D steers were heavier (P &amp;lt; 0.01) than P steers; however, finishing ADG was greater (P &amp;lt; 0.01) for P compared with D. Conversely, hot carcass weight of P steers was less (P &amp;lt; 0.01) compared with D steers. Drylot steers had greater DMI (P &amp;lt; 0.01) than P steers during finishing, whereas P steers had improved G:F (P &amp;lt; 0.01) compared with D steers. There were no differences (P \u2265 0.19) between treatments in DOF, carcass characteristics or United States Department of Agriculture yield grade. Growth and health during a 56-d weaning period and a 56-d receiving period were improved when steers were weaned in a drylot environment and fed a concentrate-based diet compared with non-supplemented steers weaned in a pasture environment. We interpret these data to suggest that, under the conditions of our experiment, steers preconditioned on mature, native, warm-season pasture for 56 d without supplementation were unable to compensate for previous nutrient restriction during finishing.<\/jats:p>","DOI":"10.1093\/tas\/txac030","type":"journal-article","created":{"date-parts":[[2022,3,7]],"date-time":"2022-03-07T17:30:21Z","timestamp":1646674221000},"source":"Crossref","is-referenced-by-count":1,"title":["Effects of weaning method on postweaning performance by early weaned beef calves"],"prefix":"10.1093","volume":"6","author":[{"given":"John R","family":"Jaeger","sequence":"first","affiliation":[{"name":"Western Kansas Agricultural Research and Extension Center \u2013 Hays, Kansas State University, Hays, KS 67601, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garrett W","family":"Preedy","sequence":"additional","affiliation":[{"name":"Department of Animal Science and Industry, Kansas State University, Manhattan, KS 66506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin W","family":"Waggoner","sequence":"additional","affiliation":[{"name":"Western Kansas Agricultural Research and Extension Center \u2013 Hays, Kansas State University, Hays, KS 67601, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith R","family":"Harmoney","sequence":"additional","affiliation":[{"name":"Western Kansas Agricultural Research and Extension Center \u2013 Hays, Kansas State University, Hays, KS 67601, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K C","family":"Olson","sequence":"additional","affiliation":[{"name":"Department of Animal Science and Industry, Kansas State University, Manhattan, KS 66506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,3,7]]},"reference":[{"key":"2022041207072691100_CIT0001","doi-asserted-by":"crossref","first-page":"596","DOI":"10.1016\/j.meatsci.2008.10.017","article-title":"Effects of vitamin a supplementation and weaning age on serum and liver retinol concentrations, carcass traits, and lipid composition in market beef cattle","volume":"81","author":"Arnett","year":"2009","journal-title":"Meat Sci"},{"key":"2022041207072691100_CIT0002","first-page":"25","article-title":"Effect of weaning method on welfare and performance of beef calves during receiving.","volume":"63","author":"Bailey","year":"2012","journal-title":"Proc.
