Tail docking in cattle, including Australian breeds, is a husbandry practice performed for several practical reasons, though it remains a subject of animal welfare debate.
The practice is contentious. Animal welfare organizations argue docking causes acute pain and chronic distress, and may impair natural fly-swatting behavior. In many jurisdictions, it is restricted or banned unless performed by a veterinarian for therapeutic reasons. Where permitted, it must comply with strict guidelines (e.g., use of analgesia, age limits) to minimize suffering.
Producers should consult local regulations and veterinary advice before docking.
