The antlers are usually shed in March or April, and begin regrowing in May, when the bony growth is nourished by blood vessels and covered by furry-looking "velvet." Antler growth ceases each year by August, when the velvet dries up and bulls begin to scrape it off by rubbing against trees, in preparation for the autumn mating season or rut.
The individual deer's nutritional needs for antler growth is dependent on the diet of the deer, particularly protein intake. Good antler-growth nutritional needs (calcium) and good genetics combine to produce wall trophies in some of their range. [24]
Now, scientists want to take the cells that power deer antler growth and figure out how to give that same ability to humans. Deer grow antlers anew each spring. Now, scientists want to take the ...
Growth occurs at the tip, and is initially cartilage, which is later replaced by bone tissue. Once the antler has achieved its full size, the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler. In most cases, the bone at the base is destroyed by osteoclasts and the antlers fall off at some point. [6]
Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer such as elk, moose, and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing.
Deer were an important source of food for early hominids. In China, Homo erectus fed upon the sika deer, while the red deer was hunted in Germany. In the Upper Palaeolithic, the reindeer was the staple food for Cro-Magnon people, [94] while the cave paintings at Lascaux in southwestern France include some 90 images of stags. [95]
In fact, argues Phipps, certain nutrients can be tied directly to the stages of hair growth and loss. "The hair growth cycle has 3 phases: anagen, catagen, and telogen," she explains. "Anagen is ...
