Docking Lamb Tails: Why It’s Done and How to Do It Humanely

Most sheep breeds are born with long tails, which might seem harmless at first. However, under the farming conditions in New Zealand, long tails can lead to two significant problems. First, if a lamb experiences diarrhea, the tail can become soiled with faeces, which can cause hygiene issues and attract flies. Second, long tails are an inconvenience for shearers, making the process more difficult and time-consuming.

As a result, the long-standing practice of "docking" – or removing lambs' tails – has become common. At the same time, ram lambs that aren’t intended for breeding are typically castrated. While docking is undoubtedly painful for lambs, it's a necessary procedure. 

The Most Humane Methods of Docking

Fortunately, research has been done to find the least painful methods of docking. The use of rubber rings is widely regarded as the most humane way to dock lambs' tails. This method should be done within the first four weeks of the lamb’s life, ideally within the first two weeks. It's a good idea to have someone experienced demonstrate the procedure to ensure it’s done correctly and as painlessly as possible.

For ram lambs, administering a small amount of local anesthetic into the scrotum before applying the rubber rings can significantly reduce their distress. It’s worth discussing this option with your vet, who can provide guidance on how to properly administer the anesthetic.

Docking, though a necessary procedure, can be done in ways that minimize pain and risk to lambs. Always consult with your vet or an experienced farmer to ensure you're following the most humane and effective practices.

All the best, Euan.
