What is Numnuts?
Numnuts® is a 2-in-1 device that administers an Elastrator® ring (refer to your vet) along with a pre-calibrated dose of local anaesthetic (refer to your vet). This device makes giving fast-acting targeted pain relief for castration and tail docking of lambs easy, fast, and safe. No other device exists that allows farmers and vets to provide targeted pain relief to lambs during tail docking and castration.
The Numnuts® Device allows farmers and vets to provide best practice without compromising on safety and efficiency. The device is robust, blood-free, and needle-safe. The modular design allows for parts to be changed to maintain good hygiene and efficient function. Numnuts® is a Scottish designed and developed product that has proven its reliability over five lambing seasons – Numnuts has been used by thousands of pioneering sheep farmers and vets and has been used to administer over 3 Million doses in Australia and New Zealand as of January 2024.
“Numnuts is a fascinating product… I used myself first hand tailing lambs and I’m totally converted with the ease of use and very clear improvement in lamb behaviour.”
Ivan Holloway, Technical Veterinarian

Durability Testing
During development, Numnuts worked with farmers to define key elements such as ergonomics, function, weight, etc. They also gave us the challenge of making it last at least 100,000 cycles. So, to meet that challenge, we built a rig to test and improve the durability.
“We marked our lambs this year with Numnuts and the improvement in our lambs’ recoveries was huge! Our lambs were on their feet, walking off and feeding from the ewes almost instantly. We will be using Numnuts next season!”
Sally Paterson, Farmer and Vet Nurse, Geelong
Please note:
you must source your bottle of local anaesthetic through your own veterinary practice. The calibrated dose through the device is 1.5ml of anaesthetic.
Recommended for lambs 4 weeks and older.
The Numnuts device requires maintenance to ensure it remains reliable – please replace your needles & Fluid Junction regularly. Spares of these are readily available.
