VAU has the most epiphysiseal content. VAU(or upper region of the deer antler) was most anabolic to longitudinal bone growth. Antler eating and antler growth in wild Axis deer Antler eating and antler growth in wild Axis deer BARRETTE, C. 1985-01-01 00:00:00 INTRODUCTION Except for Moschus sp. Photograph courtesy of Uwe and Hans Kierdorf, Justus Liebig University of Giessen, Germany. That is why You can see a visual difference from year-to-year in individual specimens and certain age groups. Most temperate deer shed their antlers annually.
Numerous bony protuberances (‘antleromas’) can be observed over the antler surface. John D. Williams, Ph.D. Associate Professor Veterinary Medicine, Texas A&M University Reproduced from The Journal of the Texas Trophy Hunters, September/October 1994. Causing calcification to occur and the Antlers to harden. Antler growth, unlike that of horns, is apical (terminal); surgical removal of the apex of an antler prevents further growth (Goss, 1961). The pedicles scab over within a couple of hours and new antler growth begins. If so, then the antler characteristics within a deer herd can be changed through selection. and Hydropotes inermis all Cervidae have antlers (Chapman 1975 ; Goss 1983). [Frontiers in Bioscience E4, 1111-1126, January 1, 2012] 1111 Endocrine relationships between rank - related behavior and antler growth in deer
Decreasing daylight hours stimulates the levels of testosterone in most species of deer. Deer Antler also stimulated osteoblastic growth which the scientists speculated is likely contribute to the longitudinal bone growth. These weights are roughly similar wherever axis deer are found. Despite the framework formation of Roe antlers being different, the antler growth proceeds by endochordal ossification in all three species. A Hog deer (Axis porcinus) stag that has very recently cast his right antler. (C) The antler of a castrated fallow deer. Other deer, including the Indian sambar, Rusa unicolor, can carry a single set of antlers for several years. In Hawaii, bucks weighed up to 250 pounds on Molokai (Graf & Nichols 1967). (B) Antler of a red deer stag that was orchidectomized during the first month of antler growth; this results in retention of the velvet skin. Some exceptions have been noted. Local treatment of deer pedicles with RA prior to growth of the first antler resulted in increased antler size, suggesting that RA increases the proliferation of the mesenchymal cells derived from the periosteum (Kierfodrf and Kierdorf, 1998; Kierdorf and Bartos, 1999). Bucks in India weighed 150-200 pounds, while does weighed 100-125 pounds. Male axis deer are generally larger than female axis deer wherever they occur. Part 2 of Spikes Are Not Inferior - Or, Are They? White-tailed Deer Are Antler Characteristics Inherited?
Note though that growth rate does not always correlate with total growth. Hormonal growth occurs in all species of antlered deer annually.
