The gold standard in calf implants.
For more than 50 years, RALGRO has been known for heavier weaning weights that deliver greater revenue in calf crops.
RALGRO provides cow-calf producers implanting ease, flexibility and most important – results.
IMPLANTS FOR BEEF CATTLE
A single pull of the RALOGUN® trigger delivers the proper 36-mg dose (three – 12-mg pellets per chamber).
RALGRO (zeranol implants) is an anabolic agent that increases rate of weight gain and improves feed efficiency of weaned beef calves, growing beef cattle, feedlot steers, and feedlot heifers. RALGRO also increases rate of weight gain of suckling beef calves.
Increased weight gain through weaning.
A 23-trial summary showed an average 23-lb. weaning weight advantage (over 163 days) in calves implanted with RALGRO over non-implanted controls.1
The most versatile implant on the market.
With non-sex-specific zeranol as its active component, RALGRO can be used in both male and female calves – even replacement heifers.
Easy to get implanting right.
The ergonomic design of the RALGRO RALOGUN®, combined with a small implant size, reduces fatigue while making it easy to administer pellets accurately.
Other Key Benefits

Do not use in bulls intended for reproduction or dairy animals. Do not use before 1 month of age or after weaning in heifers intended for reproduction. Edema of the vulva and udder, teat elongation, rectal and vaginal prolapse, and signs of estrus may occur when heifers are implanted. Delayed testicular development may occur in young males. To avoid difficulty in castration, young males should be castrated at the time of implanting.
