Revalor XR

Revalor XR

(trenbolone acetate 200 mg/estradiol 20 mg)

The first delayed and extended release implant licensed in Canada for both feedlot steers and heifers

Revalor®-XR is a delayed and extended release implant designed to increase the rate of weight gain and improve feed efficiency from days 70 to 200 in feedlot steers or heifers.

Long-lasting performance: Get the benefits of a performance-based terminal implant without the hassle of re-handling.

  • Only one trip through the chute for increased growth performance and improved feed conversion from days 70 to 200 after implantation.
  • Equivalent production gains when compared to a non-coated immediate release implant with equal dose of TBA and estradiol (Revalor®-200) administered on arrival (day1) or at day 70 (terminal implant)1,2†

With Revalor®-XR you can handle your steers or heifers when you decide to... not according to a re-implantation schedule

Revalor®-XR is an implant containing 200 mg of trenbolone acetate and 20 mg of estradiol. Each implant consists of 10 small pellets coated with a polymer for delayed and extended release. (See "The science behind Revalor®-XR".)

To increase rate of weight gain and improve feed efficiency during 70-200 days after implantation in feedlot steers and heifers.

Do not use in animals intended for subsequent breeding.

No withdrawal period in cattle is required when this product is used according to the label directions. Do not use in calves to be processed for veal. Do not use in dairy cattle. Implant pellets in the ear only (see "Implanting with Revalor®"). Do not attempt salvage of implant site for human or animal food. Keep out of reach of children.

Store the unopened product below 25°C in the original packaging. Do not freeze. Store the opened product cartridges in the foil pouch protected from light in a refrigerator (2-8°C). Do not use the opened product after 6 months.

†Revalor®-XR was compared to protocol of Revalor®-200 implanted on day 1 or on day 70 in steers and heifers fed for 200 days. Performance results for multiple live and carcass-adjusted endpoints were similar between implant groups (P = not significant).
