Eighty crossbred yearling heifers were used to determine the possible benefit of including 2% cement kiln dust in a typical high-concentrate finishing ration. The value of reimplanting with Ralgro during a 151-day feeding period was also evaluated.
Cattle on the cement dust ration gained 13% slower and ate 6.3% less feed per day than control heifers, resulting in an 8.5% poorer feed conversion with cement dust. Carcass quality and yield grades were not affected by cement dust in the ration.
In this study, no benefit was observed from implanting heifers twice during a 151-day feeding period as compared with a single implant in terms of finishing trial performance or carcass characteristics.
