Numnuts in Action

Numnuts is entirely unique. No other device exists that allows farmers to provide targeted pain relief to lambs during tail docking and castration. Here are some of the reviews we’ve received from our pioneering customers.

Numnuts Case Studies

Aloeburn owners, Andrew and Jodie Green, pride themselves on providing high quality fleece and meat products while also maintaining high welfare standards.

The Greens have found that by using Numnuts their lambs were back on their feet, and back to their dams, much faster. They have now integrated Numnuts into their regular lamb marking routine for both their Merino stud and main flock.

In 2019, the Patersons completed their first season with Numnuts, having applied one ring to each of their 10,000 lambs: docking tails of breeding ewes and castrating wethers. 

David says that they noticed immediate improvements in their flock’s behaviour after marking, with lambs recovering quickly and mothering up taking far less time.

Numnuts on Farm Videos

Noel Henderson | Avington Merino | Ethical Farming with Numnuts®

Avington Merino owner, Neol Henderson, was one of the first commercial Merino farms in Victoria to use Numnuts in 2019. Before Numnuts existed, a vet would come out and provide a local anaesthetic to lambs being castrated by rubber rings. The emergence of Numnuts has made that process more efficient and his farm team can now provide best practice pain relief with rubber rings.
