Abstract

One hundred seventy-nine steers were used in a 2 &#;&#;2 factorial experiment to determine if DiaFil, diatomaceous earth, enhances finishing performance. Treatments were: control; 3% DiaFil; Rumensin® and Tylan® (R/T) fed at 25 and 10 g/ton, respectively; or DiaFil + R/T (DM basis). Feeding DiaFil alone reduced daily gain compared with control and DiaFil+ R/T, while gain of steers fed R/T was intermediate. Compared with control, efficiency was reduced 8% when steers were fed DiaFilalone. Steers fed R/T or DiaFil+R/T were 9% more efficient than those fed DiaFil alone. The addition of DiaFil alone reduces dietary energy concentration.
