Routine livestock procedures including castration, dehorning, and tail docking cause significant pain, yet many are performed without pain relief in standard agricultural practice.
The scale of livestock pain from routine procedures is enormous. Castration and dehorning are performed on hundreds of millions of animals annually, often with no analgesia. Research consistently shows these procedures cause acute and lasting pain: stress hormones spike, animals show pain behaviors, productivity decreases. The cost of pain relief (meloxicam, local anesthetic) is trivial — often pennies per animal. The barrier is inertia, lack of legal requirements, and unfamiliarity. Several large retailers and food companies have begun requiring analgesia as a supply chain standard.
