whitetail deer antler growth by age

Improving the age structure of bucks will lead to better-antlered bucks because it requires no physical or monetary inputs. White-tailed deer antlers usually have more prominent brow tines and lack the bifurcated branching present in mule deer. Spongy bone is highly vascularized during growth, which allows the transport of nutrients and growth regulating hormones. Ultimately, they resemble a doe with antlers. Deer Antler Growth Over Years The buck reaches antler maturity at six years. 1 1/2 years of age = 29 percent of buck’s antler growth, 2 1/2 years of age = 61 percent of buck’s antler growth, 3 1/2 years of age = 79 percent of buck’s antler growth, 4 1/2 years of age = 91 percent of buck’s antler growth, 5 1/2 years of age = 98 percent of buck’s antler growth, 6 1/2 years of age = 100 percent of buck’s antler growth. Culling for larger antlers — which many deer biologists agree is a pointless task — is among them. 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). Then pictures of bucks can be studied at length, and from many different angles, to estimate the age of a buck. The key to proper buck harvest management is being able to accurately age deer on the hoof. One of the best ways to ensure proper buck harvest is through the use of motion-triggered game cameras. It grows fully until 6 years. Your email address will not be published. For example, when hunters consistently shoot the biggest-antlered bucks when they are young and do not allow them to mature into older bucks, the herd is left with a larger percentage of bucks with lower antler growth potential. Whitetail antler genetics has long been a hot-button topic among deer hunters. Restriction of blood supply around the autumn equinox causes the velvet's death; when dry enough, velvet is removed in as little as 24 hours by thrashing on vegetation. Secondly, most bucks are still stressed from the long winter so their overall body is in recovery mode. His body size fits the mold of a 3 1/2 to possibly 4 1/2 year old deer. Itchy trigger fingers will postpone long-term goals. 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. 8 Years Old and Older. As a deer continues growing through its second year of life, its permanent premolars are lost and replaced, much like our baby teeth drop out in our younger years. They will grow a new set of antlers yearly. The covering of the growing antler takes on the appearance of shiny velvet because sparse hairs grow straight out and are coated with oily secretions from the hair follicle. For older age classes, however, you can forget it. After six years, antler growth generally decreases. Beneath the wound epithelium are cells which will create the antler growth zones. Antlers from the same deer at ages 3, 4, and 5 years showing consistency of general conformation, annual variation in presence of tines (a), and abnormal points increasing at older ages (b). The factors that dictate year to year growth are the age of the animal, its genetic makeup, and its nutritional intake. There are two types of bone within an antler, spongy bone and compact (cortical) bone. Age, diet and health are determining factors in the size, shape and color of the whitetail deer's antlers. Once mineralized, chondroclasts resorb the cartilage, and bone is laid down on the remaining "scaffold" by osteoblasts. Antlers grow rapidly from their pedicle (base) while in velvet during the spring and summer, as fast as 3/4 inch/week for yearlings and 1 1/2 inches per week for adults during peak growth (Jacobson and Griffin 1983). 3 1/2: When a whitetail reaches 3 1/2 years of age, its skeletal frame is done growing. 5 1/2 years of age = 98 percent of buck’s antler growth. Spongy bone makes up the inner portion and is less dense, softer, and weaker. With proper nutrition equal, antlers will get larger each year until about six years of age. High-grading is one of the most common white-tailed deer management mistakes made when the goal is grow bigger-antlered bucks. They generally have loose skin on their face, neck and shoulders – usually visible as a “chin flap” – and they may have pointed shoulder and hip bones. At 1½ years, bucks are all legs. The early antler growth on these bucks was obvious and aroused the curiosity of my deer breeder / biologist friend. 6 1/2 years of age = 100 percent of buck’s antler growth. After disclosing the Mass XL story he went on-line and ordered 8 jugs for himself. On average, bucks grow bigger antlers each year up to about 6 1/2 years of age, and then it's flat from there. 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.

The enlarged and columnar chondrocytes then begin the process of mineralization. A few free-ranging bucks make it to the post-mature age category. Once he peeled velve… Lingual crests, or the pointy ends of molars, are sharp when the teeth fi… This area reacts like any wound, bleeding for a short period and developing a scab-like covering called a "wound epithelium" within 2-3 weeks. Points or tines are classified as typical (points generally symmetric and arising from the top of the main beam) and abnormal or non-typical (points arising from other than the top of the main beam or asymmetrical with the other side). Your email address will not be published. Spongy bone makes up about half the diameter of an average antler (McDonald et al. Growth rate slows dramatically during late summer while mineralization of the antler … Whitetail bucks will often increase antler points as they get older, but their antlers will peak and begin to decline if the buck is allowed to get really old, becomes ill, gets injured or if nutrition falls off. The deer may not be observed while deer hunting, but cameras do allow management-minded hunters to classify deer as “mature shooter” or “don’t even think about it” before the season even begins. Brain abscesses, resulting from secondary infection following injury to the frontal bone or pedicle, may result in a jagged abscission line projecting deep into the pedicle and frontal bone. There is very little we can do about genetics. And this is some great info to have in your pocket when talking deer hunting and management around the campfire. The annual casting and growth of new antlers is an important part of the whitetail's mystique. As a result, the local deer herd may have a 3 1/2 year old and a 5 1/2 year old buck that both score around 125 inches. Over its lifetime, the deer will develop and shed antlers, with new, uniquely-shaped antlers appearing each time. Abscission line at the antler — pedicle interface. The back of the deer will also slope at a sharp downward grade from the rump to the shoulder. 4.5-Year-Old Bucks and Older Once you get to a 4.5-year-old buck, in most people’s minds, you have a fully mature whitetail.
