Supplemental Trace Minerals (Zn, Cu, and Mn) as Sulfates or Hydroxy Trace Mineral Sources for Beef Heifers
<p>Crossbred heifers (n = 286, 255 ± 4.5 kg initial BW, 295 ± 16.5 d of age) were used over a 2-yr period to determine the effects of mineral source on beef heifer development at 2 locations (n = 71 and n = 72, Fayetteville, blocks 1 and 4; n = 72 in each of 2 breeding groups, Batesville, blocks 2 …
