deer
Male white-tailed deer (Odocoileus virginianus).
The time required for a deer to grow its antlers varies by species, but generally, the process takes up to 150 days.123
During this period, the growing antlers are covered in "velvet," a highly vascularized, nerve-filled skin. Once the growth phase is complete, the velvet dies and is removed as the deer rubs its antlers against trees and branches. Antlers are grown annually as an energy-intensive process, requiring significant amounts of protein and minerals. While most deer shed their antlers after the mating season, some territorial tropical species may retain them for more than a year.231
