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.

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.

Debunking the Myths of Implanting

For an investment of approximately $1.50 per head, implants like RALGRO® result in a $30-$50 increase in calf value.5 So why don’t more calves receive one? Some common misperceptions may be to blame.
