Two commercial feedyard experiments evaluated implant strategies for feedlot heifers. In both experiments, implanting heifers with Synovex Plus increased ADG compared to heifers implanted with Finaplix-H and fed MGA. In Experiment 1, implanting heifers with Synovex Plus improved feed conversion and increased live basis net returns, and the use of MGA with Synovex Plus increased carcass merit basis net returns and had similar marbling scores compared with Finaplix-H and MGA
