Forty lambs were offered four-way choices among inorganic sources of P and Mg: magnesium oxide in its coarse 1) C-MgO and granular 2) MgO forms and magnesium phosphate: 3) Mag33 (33% Mg and 2.7% P), and 4) MGP (25% Mg and 15% P), and two-way choices between MGP and each of the other minerals, and between MgO and C-MgO (baseline). Subsequently, lambs were randomly assigned to four groups (10 lambs\/group) and fed rations such that the levels of Mg and P were low (LMg_LP), adequate (NMg_NP), low in Mg and adequate in P (LMg_NP), or adequate in Mg and low in P (NMg_LP). After 29 d, choice tests (post-deficiency) were repeated. During baseline, lambs ate and preferred Mag33 &amp;gt; C-MgO = MGP &amp;gt; MgO (P &amp;lt; 0.05). This pattern remained during post-deficiency tests, but lambs in LMg_LP and LMg_NP increased their preference for MGP and C-MgO, respectively, whereas lambs in NMg_LP increased their preference for C-MgO and MGP relative to baseline (P &amp;lt; 0.05). The serum concentrations of P and Mg increased after preference tests, and preference for MgO and MGP in low-Mg groups increased as the serum concentration of Mg declined (P &amp;lt; 0.05). Thus, lambs discriminated among different minerals and some groups modified their preferences based on the basal diets received, which rectified mineral imbalances.<\/jats:p>","DOI":"10.1093\/jas\/skab010","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T14:47:56Z","timestamp":1610722076000},"source":"Crossref","is-referenced-by-count":3,"title":["Preference for inorganic sources of magnesium and phosphorus in sheep as a function of need"],"prefix":"10.1093","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6912-056X","authenticated-orcid":false,"given":"Mariana","family":"Pedernera","sequence":"first","affiliation":[{"name":"Facultad de Ciencias Agropecuarias, Universidad Aut\u00f3noma del Estado de Morelos, Cuernavaca, Morelos, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Mereu","sequence":"additional","affiliation":[{"name":"Yara Iberian, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8868-8468","authenticated-orcid":false,"given":"Juan J","family":"Villalba","sequence":"additional","affiliation":[{"name":"Department of Wildland Resources, Utah State University, Logan, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,1,15]]},"reference":[{"key":"2021020216455862400_CIT0001","volume-title":"Official methods of analysis","author":"AOAC.","year":"2000","edition":"17"},{"key":"2021020216455862400_CIT0002","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1016\/j.livprodsci.2005.09.012","article-title":"Diet selection by growing lambs offered whole barley and a protein supplement, free choice: effects on performance and digestion","volume":"101","author":"Askar","year":"2006","journal-title":"Livest.
