Antler velvet removal from farmed deer for traditional medicine markets causes pain and stress, raising significant welfare concerns across the global deer farming industry.
Growing antlers are richly innervated and vascularised. Cutting them without anaesthesia causes acute pain equivalent to cutting a finger. Even with anaesthesia, regrowth and annual removal represent repeated welfare events. Farmed deer also experience chronic stress from confinement, as semi-wild animals have large natural home ranges.
