Product information
RALGRO®
(zeranol implants)
IMPLANTS FOR BEEF CATTLE
A single pull of the RALOGUN® trigger delivers the proper 36-mg dose (three – 12-mg pellets per chamber).
Indications
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.
Key Benefits
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
- Doesn’t affect post-weaning and finishing performance.2
- Reaches effective levels within the first day of administration.3
