Plasma Zn tends to respond to implant and Zn treatments throughout study. Steers received either no hormonal implant (NoIMP) or were implanted with Component TE-IS on day 0 followed by Component TE-200 on day 57 (IS/200; Elanco) and fed 70 mg Zn/kg DM from ZnSO4 + 30 mg Zn/kg DM from basic ZnCl, Zn glycinate, or ZnSO4 (ZnB, ZnG, and ZnS, respectively). Blood was collected on days −1, 15, 56, 71/72, and 125 for plasma trace mineral analysis. Data were analyzed using repeated measures of the mixed procedure of SAS.
