Deer antler in velvet is a live, richly innervated structure; its removal in deer farming and the natural rubbing of antlers in wild deer both have welfare implications.
Deer antler welfare spans both wild and farmed contexts. In velvet antler farming, the removal of the blood-filled, innervated velvet antler for the traditional medicine market is performed on animals restrained in crushes, causing acute pain without sedation in countries where this is not regulated. New Zealand's requirement for sedation before velvet removal represents a significant welfare improvement. In wild deer, the rut involves antler combat that causes injuries ranging from minor to fatal; individual deer welfare during this period is significantly affected by fight outcomes. The natural shedding of hard antler each year is not a welfare concern as it occurs through a natural dissolution process.
