In this episode of RaboTalk’s Growing Our Future, host Katie speaks with agri‑innovator Leon Spurrell about an implant technology that manages udder health and antibiotic use. Backed by Lincoln University trials and strong farmer feedback, the implant works by strengthening cows’ natural defences, helping prevent mastitis, maintaining milk quality and extending an animal’s productivity.
Leon shares how the technology is delivering promising results and offers a cost‑effective alternative to traditional treatments for dairy systems. For farmers and growers interested in practical innovation and reduced antimicrobial reliance, this episode offers compelling insights into the future of animal health and welfare.

Show Notes:
In this episode of Growing Our Future, host Katie sits down with Leon Spurrell, founder and agri-innovator, to discuss a pioneering implant technology that could change how farmers approach udder health and longevity in dairy cows. Developed through extensive research and supported by Lincoln University trials, the implant offers a sustainable alternative to antibiotics - extending cow lifespans, improving productivity, and leaving no residue in milk.
A New Frontier in Udder Health
Leon explains how his team’s implant technology helps prevent mastitis by strengthening the cow’s natural defences rather than relying on antibiotics or teat sealants. The goal is simple yet ambitious - to help cows stay in the herd for several extra lactations while maintaining milk quality and animal welfare.
Early trials have shown strong results. “We’ve seen implants still working beautifully after two years,” Leon says. “If we can extend a cow’s life by a couple of lactations without antibiotics, that’s a win for everyone - farmers, processors, and consumers.”
Backed by Research and Farmer Feedback
Independent studies with Lincoln University have confirmed promising levels of activity in the implants, validating their performance under New Zealand conditions. Farmers involved in early trials have also been enthusiastic, describing the results as “game-changing” and the costs surprisingly low - around $120 per cow.
With production currently spread across the United States, Canada, and China, Leon hopes to bring full-scale manufacturing home to New Zealand. “We’ve got the capability now,” he says. “If we find the right partner, we can produce everything locally.”
Innovation with Global Potential
While initially designed for dairy cows, the implant’s benefits may extend further. Leon, who even trialled it on himself for joint inflammation, says the technology shows promise in reducing inflammation and improving metabolic function. “It’s working beautifully,” he laughs. “It could have applications beyond animal health - maybe even for people.”
As demand grows, automation and robotics are being integrated into production to ensure scalability while maintaining quality. Leon stresses the importance of partnering with organisations committed to reducing antimicrobial use and supporting sustainable farming systems worldwide.
Overcoming Industry Barriers
Despite the strong potential, Leon acknowledges that disruption comes with resistance. “The biggest barrier will be existing players in the industry,” he says. “But innovation has to move forward. My goal is to get this technology into the world - not to see it shelved.”
He believes that collaboration, transparency, and a focus on shared value will be key to success. “If more people benefit from it, then we’re winning,” he concludes.
Key Takeaway
Leon Spurrell’s work highlights how farmer-led innovation can deliver practical, science-backed solutions for animal health and sustainability. His vision - reducing antibiotics, extending productivity, and improving welfare - reflects the future of responsible, resilient dairy farming.
