The antlers of this male is covered by a soft shiny skin known as velvet. This generally happens during the growth of the antlers. The velvet is very sensitive as it is fed by many blood vessels and is vulnerable to injuries. When the antlers grow to take their final shape a ring of bone forms on the base and cuts off the supply of blood to the velvet thus leading to its shedding. During this period many deer can be seen rubbing their antlers on the tree trunk to get rid of the velvet.
Availability of good grass plays a important role during the process of shedding as they need good source of calcium to help the formation of bone (antlers).
