Effects of implant or intake level on plasma urea nitrogen. Plasma urea nitrogen concentration of steers (Chart A) either implanted (solid line) or not implanted (dashed line) with a long-acting TBA:E2 implant; and (Chart B) fed a common diet at either 2.0 (solid line; HIGH) or 1.0 (dashed line; LOW) × maintenance NE requirements. (Effect of intake P = 0.56; implant P = 0.62; intake × implant P = 0.99; day × intake P < 0.01; day × implant P = 0.33; day × intake × implant P = 0.12. Pooled SE for treatment means was 0.261. a,bmeans without a common superscript differ (P < 0.05).
