The defined production phases for beef cattle left some lingering questions for many in the beef industry, especially with the production phase of dry lot and how it differs from growing on pasture and the confinement for slaughter production phase. GFI #191 and associated documents from FDA have helped define the dry lot production phase. The dry lot phase is an opportunity for beef producers to add value to the cattle in their care. Earlier this year, Zoetis received an additional label indication for its Synovex Choice® implant in the dry lot production phase, as well as gained approval on a new implant product for the dry lot, Synovex® PrimerTM. These are the first TBA-containing implants approved for the dry lot production phase, and it gives producers in the dry lot phase more options.
