The benefits of consistent implanting add up.
Cattle implanted at each stage of production stand to gain up to an additional 195 pounds over the course of their lifetime when compared to non-implanted cattle.1 That’s a lot of extra gain with no additional grazing or feed resources.

Cartridges for Cash Toolbox
Nearly $150,000 Donated Through Cartridges for Cash Program
The concept is simple. Save your empty REVALOR® (trenbolone acetate and estradiol implants, trenbolone acetate and estradiol extended-release implants) or RALGRO® (zeranol implants) cartridges and give them to a participating state cattlemen’s association.
Merck Animal Health will donate 25 cents for every cartridge up to a maximum of $10,000 annually/state to support ongoing youth initiatives.
States involved in Cartridges for Cash are: Florida, Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, Oklahoma, Tennessee and Texas. For more information contact your state cattlemen’s association.
Implant today, impact tomorrow.
There is mounting pressure to be more sustainable, and many worry they will have to sacrifice their bottom line to do it. See how our growth-promoting implants can help you both achieve sustainability and turn a greater profit.
For cow-calf producers, pre-weaning implants have clear advantages.
There’s a perception that non-implanted calves garner a higher premium on sale day than their implanted counterparts. However, data consistently shows no difference in sale price between implanted and non-implanted calves.2
RALGRO® (zeranol implants) increases weaning weight by 23 pounds on average compared to non-implanted calves. With results like that, it’s easy to see how cattle implants at the cow-calf level can result in a favorable payday.3
Implants help stockers perform in the pasture and beyond.
Research has proven that when the right cattle implants are given at the correct stage, cattle will continue to perform in the following stage. That means implanting stocker cattle has no negative impact on future performance at the feedlot.
With an implant designed just for stocker cattle like REVALOR®-G (trenbolone acetate and estradiol implants), stockers on pasture gain an extra 23 pounds on average. And they maintain the added weight during the finishing period.3
For feedlot producers and farm feeders, implants secure valuable gains.
Implanted cattle stand to gain an additional 120 pounds over non-implanted cattle, using the same amount of resources.6 REVALOR®-XS and -XH (trenbolone acetate and estradiol extended-release implants) help optimize productivity throughout the finishing period — with no re-implanting necessary.
The gains of re-implanting without the hassle. That’s the X Factor.
With one-of-a-kind dual-release technology, REVALOR-XS and -XH implants are able to deliver two distinct doses in a single implant. That gives feedlot cattle the right dose they need when they need it with no added stress or loss of feed intake and no extra labor for producers.
It all adds up to big gains in live and hot carcass weight over non-implanted cattle – and can even outperform re-implanting.6,7
Is a feedlot re-implant necessary?
With the right implant now, there’s no need to re-implant later.
While a second dose is desirable to boost performance, re-implanting itself is not – which is why the implant you choose matters. See how REVALOR-XS and -XH can maximize gains at the feedlot.
Implant Today, Impact Tomorrow Producer Panel
At the 2022 NCBA Trade Show, cattle producers came together to discuss the overall impact of implants. Producers who participated in the panel discussed the opportunity for both improved environmental and financial sustainability through the use of cattle implants.
