Deer farming for velvet antler — sold as a nutritional supplement — involves practices that cause significant pain and distress to the animals.
Velvet antler harvesting represents a case where an animal product with questionable human benefit is obtained through a procedure that causes significant pain when done without adequate analgesia. The antlers at velvet stage are living tissue with active nerve supply — their removal is equivalent to a significant surgical procedure. Requiring veterinary supervision and appropriate anesthesia represents a minimum welfare standard, but the justification for the practice itself warrants scrutiny given the limited evidence for human health benefits.
