Overview
Revalor-XH is an implant containing 200 mg of trenbolone acetate and 20 mg of estradiol. It is designed for heifers fed in confinement and provides two doses in a single implant. The first dose, designed to be given when cattle are processed, is effective immediately, while the second dose, shielded by patented X7™ polymer coating, goes to work 70 to 80 days later without the need to re-process the cattle. Each implant consists of 10 small yellow pellets and each cartridge contains 10 implants.
Product Features
Not only is Revalor-XH a long-lasting heifer-only implant, but it is also a fast-acting implant that eliminates the need to re-process the cattle. Revalor-XH will start working immediately with the four uncoated pellets, then the six coated pellets go to work ~70-80 days later and will keep working up to 200 days.
Indications
Revalor-XH is indicated for increased rate of weight gain and improved feed efficiency for up to 200 days after implantation in beef heifers fed in confinement for slaughter. Do not use in calves to be processed for veal. Effectiveness and animal safety in veal calves have not been established. Not approved for repeated implantation (reimplantation) with this or any other cattle ear implant during the production phase(s) identified on labeling [beef heifers fed in confinement for slaughter] unless otherwise indicated on labeling because safety and effectiveness have not been evaluated. Not to be used in animals intended for subsequent breeding, or in lactating dairy cows.
Note: dStudies have demonstrated that the administration of Revalor®-XH can result in decreased marbling scores when compared to non-implanted heifers.
