NumOcaine is the approved local anaesthetic for Numnuts. It works by affecting the permeability of nerve cell membranes to sodium ions, thus blocking nerve impulse transmission. All nerves are effected but those concerned with pain and temperature are most sensitive. Onset of action is rapid when given by injection.
Engineered to work around your current process for tail docking and castration with elastrator rings. NumOcaine comes in 100mL bottles, giving roughly 65 procedures per bottle
The QCC technology removes the need for cumbersome tubes.
QCC technology enables fast broaching and attachment to the Numnuts device.
The QCC acts as tamper security so you know you’re buying genuine NumOcaine. It also limits access to the local anaesthetic when not attached to a Numnuts device.
It’s designed to be simple and fast. Simply push the orange cap down to broach the bottle and twist the bottle onto the Numnuts device.
To prime, open the tool lightly and press the plunger 2-3 times until you see the fluid chamber fill up.

At the point of assembly, we run each QCC through a test exercise to check it’s fit for purpose before it is attached to a NumOcaine bottles and distributed. We do this with the QCC’s to ensure success on the field.
A farmer’s goal is for their animals to grow as quickly as possible. Setbacks – when animals stop growing or even lose weight – must be avoided or minimised. Well-evidenced veterinary research has highlighted that severe pain can restrict healthy development.
30 years of veterinary research carried out in New Zealand, Australia and the UK has identified injectable local anaesthetic as the preferred solution for pain relief during castration and tail docking with rings. It provides fast acting pain relief in the first 45 minutes, when lambs experience the most acute pain caused by the loss of blood flow.
Local anaesthetics are very fast acting and block this pain.

For many years, veterinary research has shown that pain after marking can be alleviated by local anaesthetic. However, until now, the risk of needle stick injury to the farmer, the time required to administer the drug by needle and syringe, and uncertainty about how and where to administer it have created a barrier to use of local anaesthetics by farmers.
Numnuts is a game changer, enabling sheep handlers to accurately inject local anaesthetic (NumOcaine®) at the same time as ring application.
In trials conducted by CSIRO and the University of Melbourne, Numnuts substantially reduced the number of lambs displaying pain behaviours immediately after marking.
With any assessment of pain there is a massive grey scale. Like with humans, some lambs are very stoic and will just ‘grit their teeth’ and bear it, whereas others show a wide range of pain behaviours.
As with other on-farm pain management practices, Numnuts does not eliminate pain. However, veterinary field trials in the UK and Australia have demonstrated a substantial reduction in pain behaviours compared to lambs marked without Numnuts.
The efficacy of Numnuts has been studied in field trials by CSIRO in Australia, and in pen trials by Moredun Research Institute in Scotland. During Numnuts’ development, more than 1000 lambs have been studied.
