Abnormalities include kicker points projecting laterally from a tine or beam, drop tines projecting downward from a main beam, extra main beams, palmation of the main beam or between tines, and clustered tines. Beneath the velvet epidermis and dermis of the growing antler is a thick, fibrous protective membrane, called perichondrium when it covers the cartilagenous growth stage and periosteum when it covers the boney stage of the growing antler. Some deer antlers exhibit annual variation in conformation, and a deer's last antler set may be quite abnormal. A buck will likely make his greatest leap in antler size, as a percentage of his lifetime potential, from 1½ to 2½ years of age – nearly doubling his antler size and expanding from only 30% of his potential to 60% of his potential. Studies have showed the average Whitetail Buck achieves only about 10 percent of his potential antler development by age 1.5 years (at the completion of his first set of antlers as an 18 month old buck). 2005), although there is considerable variation among animals. Managers must also be able to age deer by teeth in order to verify the harvested deer. However, the antler growth potential of these deer will vary, as the 3 1/2 year old would score about 150 inches given the chance to reach 5 1/2 years old. A similar situation occurs in the other direction, in that Sitka black-tailed deer antlers resemble those of white-tailed deer.

Deer hunters and manager can use this information to avoid removing the younger, larger-antlered bucks. One of the best ways to ensure proper buck harvest is through the use of motion-triggered game cameras. Antler pedicles start developing on the frontal bones of male whitetail deer fawns during late fetal development. At 3 1/2 this buck was again an 8-pointer, but now he is beginning to show antler potential. Buck Harvest Management: Bigger Antlers Await. Antler growth begins shortly after completion of the wound epithelium in white-tailed deer and most members of the deer family; in contrast, moose antlers do not begin growth until two — three months after antler casting. In the chondroprogenitor region these young cells begin to differentiate into chondrocytes and to form the columnar structure characteristic of cartilage and bone. Over its lifetime, the deer will develop and shed antlers, with new, uniquely-shaped antlers appearing each time. Spongy bone makes up about half the diameter of an average antler (McDonald et al. Another deer at maturity (C) and the year of his death (D). This is a crucial stage in a whitetail’s life.

Some individual bucks will stray from that average, gaining antler inches after that age, or losing antler inches when they're younger than that, depending on factors like annual nutrition, weather, injuries, etc. White-tailed deer antlers usually have more prominent brow tines and lack the bifurcated branching present in mule deer.

With proper nutrition equal, antlers will get larger each year until about six years of age. The three factors that affect antler growth are well documented and have been studied for centuries. 6 1/2 years of age = 100 percent of buck’s antler growth. Beneath the wound epithelium are cells which will create the antler growth zones. They will grow a new set of antlers yearly. The back of the deer will also slope at a sharp downward grade from the rump to the shoulder. Topics that surround how fast deer antlers grow, what elements are essential for trophy deer antler growth, what States provide the basic ingredients needed for antler growth of deer, conservation programs to assist in antler development of whitetail deer, and much more. Generally, antlers grow in about 120 days. The primary reason for this is that the amount of daylight is much less than what it will be in June. Antler shape or form, known as conformation, is highly variable and depends on age, genetics, and nutrition.

Once the antler is cast, the top of the pedicle can be considered an open wound. However, abnormal points arising from the second tine, similar to the bifurcated branching of mule deer, are relatively common in mature whitetails, perhaps indicative of the close taxonomic relationship of the two species. Antlers. Compact bone forms the outer shell of the antler, and its greater density and stiffness provide strength for fighting. He exhibited typical yearling buck behavior when he grew his first set of antlers, in that he shied away from older bucks when encounters took place in prime feeding areas. The enlarged and columnar chondrocytes then begin the process of mineralization. Your email address will not be published.

Beneath the velvet epidermis and dermis of the growing antler is a thick, fibrous protective membrane, called perichondrium when it covers the cartilagenous growth stage and periosteum when it covers the boney stage of the growing antler. Some deer antlers exhibit annual variation in conformation, and a deer's last antler set may be quite abnormal. A buck will likely make his greatest leap in antler size, as a percentage of his lifetime potential, from 1½ to 2½ years of age – nearly doubling his antler size and expanding from only 30% of his potential to 60% of his potential. Studies have showed the average Whitetail Buck achieves only about 10 percent of his potential antler development by age 1.5 years (at the completion of his first set of antlers as an 18 month old buck). 2005), although there is considerable variation among animals. Managers must also be able to age deer by teeth in order to verify the harvested deer.

Antler growth begins shortly after completion of the wound epithelium in white-tailed deer and most members of the deer family; in contrast, moose antlers do not begin growth until two — three months after antler casting. In the chondroprogenitor region these young cells begin to differentiate into chondrocytes and to form the columnar structure characteristic of cartilage and bone.
