Anabolic implants are used to reduce the cost of beef cattle production. Implant products are available for suckling calves, grazing cattle, and finish- ing cattle. Improvements of 6, 15, and 20% in average daily gain can be realized in calves, stockers, and feedlot cattle, respectively, with implanting. Producers have numerous choices available today when using implants to lower production costs. In the current segmented beef industry, implanting decisions are dictated by phase of production in which the cattle are marketed. General recommendations have been to use implants predomi- nately in the finishing phase, and some feedlots cur- rently offer premiums when purchasing unimplanted cattle. However, in totally integrated beef production systems, traditional implant schemes may not be opti- mal. The primary objective of an integrated system is
