| Abstract | Two hundred sixteen Angus crossbred steers (230 kg ± 5.6) purchased from sale barns were utilized to determine the impact of trace mineral source and concentration on performance, tissue metabolites, and lipid metabolism. Treatments during the 27-d receiving phase consisted of 1) inorganic trace mineral (125 mg CuSO^sub 4^/d per head, 360 mg ZnSO^sub 4^/d per head, 200 mg MnSO^sub 4^/d per head, and 12.5 mg CoCO^sub 3^/d per head) or 2) organic trace mineral (iso-amounts of Cu, Zn, Mn amino acid complexes, and Co glucoheptonate). On d 0 and 27, blood samples were collected from 3 steers per pen (pen = experimental unit). On d 28, steers were transitioned to a high concentrate finishing diet containing different concentrations of Co. Treatments during the finishing phase consisted of 1) control (no supplemental Co); 2) 0.10 mg Co/kg DM from cobalt glucoheptonate; and 3) 1.0 mg Co/kg DM from cobalt glucoheptonate. The same 3 steers per pen were bled on d 84 and 224 of the finishing phase. During the receiving phase, red blood cell superoxide dismutase activity was greater (P < 0.03) for organic- vs. inorganic-supplemented steers. During the finishing phase, overall ADG tended (P < 0.06) to be greater for steers receiving 1.0 mg Co/kg DM. Steers receiving 1.0 mg Co/kg DM had greater YG (P < 0.04) and back fat thickness (P < 0.04) than steers receiving 0.10 mg Co/kg DM. Serum, liver, and LM B12 concentrations increased (P < 0.04) as dietary Co concentration increased. [PUBLICATION ABSTRACT] |
