What is Numnuts?

Worldwide, more than 100 million lambs are castrated and tail docked each year without pain relief. The patented Numnuts® technology is a practical, farmer-friendly method for alleviating the pain suffered when lambs are castrated and tail-docked (known together as 'marking'). Numnuts® lets the farmer apply a rubber ring and inject local anaesthetic, quickly, safely and effectively. We intend to launch Numnuts® for the 2019 lambing season.

Ergonomic Banding Tool

For the first time, a banding tool that is easier to use, reducing operator RSI whilst providing super fast ring application, without bruising the animal

Injection Mechanism

An operator safe, 2-stage injection mechanism ensures you dispense the right dose of anaesthetic to the right location each and every time.

Pain Relief

The core reason to get involved with Numnuts. Our patented technology is scientifically proven to reduce tail docking and castration pain by up to 65%.
