One-and-done implants deliver pounds with less labor, stress

Dr. Brandon Nuttelman

Implanting checks a lot of boxes for cattle producers, enhancing beef cattle performance both sustainably and profitably. Growth-promoting implants have long been a staple in successful operations to maximize resources.

By “doing more with less” – using the same resources while enabling cattle to gain anywhere from 75 to 140 pounds of additional weight over non-implanted cattle1 – producers realize improved margins. And with the right implant, these results can be achieved without reimplanting.

Implementing a one-and-done approach with delayed-release implants – REVALOR®-XS for steers or REVALOR-XH for heifers (trenbolone acetate and estradiol extended-release implants) – achieves the performance benefit of a reimplanting program without the extra time and labor involved with reimplantation during the feedlot production phase.

These implants are a great option for their ease of use, cattle performance benefits and labor savings.

Two doses with one implant

REVALOR-XS and -XH were developed using novel, delayed-release technology, so they deliver two doses in a single implant. Each implant consists of four uncoated pellets that go to work immediately, plus six coated pellets that start working 70-80 days later. The coated pellets have a patented coating that allows the second dose to release slowly, working like a reimplant.

No feed intake loss

Reprocessing cattle can result in a feed intake decrease that can take 38 days to return to pre-reprocessing levels.2 With REVALOR-XS and -XH, there is no drop-off because cattle don’t have to be reimplanted, eliminating the need to put cattle through added stress and the reduction in feed intake after.

Time and labor savings

Labor savings are significant. Both REVALOR-XS and -XH eliminate the need to rework cattle for reimplantation, reducing the risk of working in extreme weather and allowing pen riders to stay focused on cattle health.

The bottom line is that a one-and-done implant procedure gives feedlot steers and heifers the dose they need, when they need it, and it carries them through the feedyard.
