Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.
