Wild Deer Loosing Antlers
Deer (and other ungulates, like elk) shed their antlers every year, then grow a completely new set. This shedding procedure takes two to three weeks to complete, while the regeneration takes an entire summer to complete — before the cycle starts all over again. Bucks shed their antlers between January and April, depending upon many factors including the animal’s age and the latitude at which it lives, after the mating season concludes.

Antlers are made up of a honeycombed bone-like tissue. The mounting points on the heads of deer from which the antlers grow are called pedicles. The antlers break off (are shed) from these pedicles. Pedicles appear on a young deer's forehead during his first year. The next year, he will develop small shafts, and by year three the first "branch" will appear. As the deer matures, the antlers will lengthen and thicken and often develop additional branches. While in the growth phase, the antlers are covered in a soft membrane referred to as "velvet," a layer of skin that supplies the growing antlers with the nutrients needed to build the bone mass. This velvet contains many substances such as amino acids, minerals, proteins and Growth Factor-1 (a protein hormone similar in molecular structure to insulin).
