Implant success in your herd and your bottom line

Getting the most out of every head in today’s beef industry is crucial to profitability. Implanting is one of the most researched and proven technologies to drive efficiency and growth. With over 30 years of implant expertise, Merck Animal Health offers a trusted line of implants for your operation’s needs.

Boosting cattle performance at every stage

cow calf

Maximize weaning weights and beyond

Implanting calves at branding with RALGRO® (zeranol implants) achieves higher weaning weights and sets them up for productivity at each stage throughout their lifetime.

Studies show:

  • RALGRO increases weaning weight by 23 lbs. on average 
compared to non-implanted calves.1
  • A study showed that calves implanted with RALGRO entered the grower phase 19 lbs. heavier on average. 2

STOCKER

Take implant performance to the pasture and beyond

An implant designed and dosed for stocker calves, 
REVALOR® -G (trenbolone acetate and estradiol implants) 
provides proven results and ROI on the pasture and beyond. 
See why it’s the #1 choice in stocker implants4:

  • Stockers implanted with REVALOR-G gain an average extra
23 lbs. on pasture.5
  • REVALOR-G matches the hormone level with the production
setting to achieve maximum productivity throughout the
grazing period.

FEEDLOT

The gains of re-implanting without the hassle

Feedlot success depends on weight gain and labor efficiency. The extended-release technology of REVALOR® -XS and -XH (trenbolone acetate and estradiol extended-release implants) deliver the performance of two doses in one, eliminating the need to re-implant —saving time and resources.

  • On average, steers implanted with REVALOR-XS gain an additional 120 lbs.
live weight or 75 lbs. in carcass weight average.6,7
  • On average, heifers implanted with REVALOR-XH gain an additional 83 lbs.
live weight and 59 lbs. in carcass weight average.6,7
  • No re-implantation means no additional processing stress and
loss of feed intake.

The benefits of implanting add up

With the proper implanting protocol, cattle stand to gain up to an additional 195 lbs. over the course of their lifetime.8

For an investment of approximately $1.50 per head, implants like RALGRO result in a $30-$50 increase in calf value.8

Implanted cattle in the feedlot are proven to increase margin by $100-$200/head depending on the implant program, DOF and cattle type.8

A shared commitment to industry-wide sustainability

Producers in the United States are the global leaders in sustainable beef production. The National Cattlemen’s Beef Association (NCBA) has doubled down on the industry’s commitment to sustainability by outlining tangible goals for the future.

Merck Animal Health supports the NCBA sustainability-driven goals:

  • Demonstrate climate neutrality of U.S. cattle production by 2040.
  • Create and enhance opportunities that result in a quantifiable increase in producer profitability and economic sustainability by 2025.
  • Enhance trust in cattle producers as responsible stewards of their animals and resources by expanding education opportunities in animal care and handling programs to further improve animal well-being.
  • Continuously improve the industry’s workforce safety and well-being.
