Abstract

A 145-day finishing trial was conducted to evaluate implant strategies on performance and carcass characteristics of yearling steers. Implanting steers with Synovex® C initially and then reimplanting with Synovex® Plus 75 days prior to slaughter improved feed efficiency compared to a single implant of Synovex® Plus or a reimplant program using Synovex® S. Carcass quality, as measured by the percentage USDA Choice carcasses and marbling scores, was unaffected by implant strategy. However, implanting steers with Synovex® PlusTM as a single implant or in a reimplant program increased profitability because feed efficiency and carcass weight were increased without decreasing carcass merit.
