Deer lose their antlers every single year, but do you know why? Depending on the severity, injuries to the leg may result in deformations to the antler in consecutive years or the deer may make a full recovery. Although the effects of mineral levels on antler size has not been documented, calcium and phosphorus levels are known to be important to antler development. Extreme velvet injuries may cause the breakage and subsequent loss of a main beam, point or entire antler. Male deer will often lock antlers and push one another to determine which individual is stronger, therefore establishing a dominance hierarchy between individual animals (Figure 4). But male deer rub off its antler after one year. Leg, pedicle and velvet injuries can all lead to antler deformations. Deer grow and shed antlers annually. Figure 7. Pedicles become visible as buttons on males at about 4 to 5 months of age (Figure 3). Severe injuries to the pedicle can result in antler deformations in consecutive years. White-tailed deer may grow deformed antlers as a result of an injury. The majority of antler growth was completed a week or so ago in early August. Timing of antler-drop may vary, but in an average season, some males shed their antlers in late December and most have shed them by early March. Granted, It may be a little different out here in California, but during turkey, the second week of May, I had a group of 3, where one had them 2 inches over his ears already, with 4 inch forks, and another had them even with his ears. Deer grow and shed antlers every year, requiring large amounts of nutrients and energy. Caribou are the only deer in which females regularly grow antlers.

Antlers reach full growth in late summer usually October. Harvesting “management” or “cull” males is a common deer management technique. Growing day length corresponds to a reduction in melatonin production, which initiates the hormone cycles responsible for antler growth. During peak antler growth periods, bucks may experience a 20 percent decrease in mineral content in other bones. Antlers are among the most identifiable characteristics of species of the deer family, Cervidae, which comprises caribou, elk, moose, mule deer and white-tailed deer (Figure 1). However, variation in antler quality among individuals may not be a good predictor of mating success. The dropping of the antlers may take place within 24 to 48 hours, but the entire shedding process may take as long as two to three weeks before the antlers actually fall … As a rule, only male deer grow antlers. Figure 10. 2011. In late August or early September, growth is completed and blood ceases to flow to the antlers. The composition of antlers change, as hardened antlers are high in dry matter and low in water content. Now during mid- and late August, the antlers start to harden. Other states, such as Kentucky, open their seasons while many bucks are still in velvet. How long will the footprints on the moon last? Populations with an abundance of older males may have a higher proportion of pedicle injuries because of the fighting that normally occurs between older males. Male white-tailed deer grow a new set of antlers every year. Each spring, a buck's antlers start to regrow almost immediately after the old antlers are shed. Males that experience such injuries typically make a full recovery the following year and grow a normal set of antlers. Mule deer, whitetail deer and other ungulates shed their antlers once a year. Velvet injuries can result in deformed hardened antlers. By August, growth slows and the antlers begin to mineralize, or harden. Antlers are pure bone, and grow larger year after year after the animal has shed; Antler Velvet – After deer shed their antlers, they quickly begin to grow them back.

Antler growth of male fawns, or “button bucks,” is generally noticeable at 4 to 5 months of age by the presence of “buttons.” At 1-1/2 years of age (yearlings), males grow their first noticeable antlers, which can range in size from spikes to 10 or more antler points. Once a deer sheds its antlers, new growth starts immediately, though visible antler growth is sometimes not apparent for several weeks. Most antler-based harvest restrictions include at least one minimum antler criteria, such as number of antler points, spread, main beam length or antler score. A deer’s genetic potential is controlled by the genetic makeup of both its parents and can affect antler shape, composition and size potential. Use our feedback form for questions or comments about this publication. However, these injuries can develop infections, causing potential health problems. Why don't libraries smell like bookstores?

Their new set of antlers grows with a cover of skin, called velvet. Every year, whitetail deer, mule deer, elk and various other hoofed mammals shed their antlers. All Rights Reserved. Since only the males typically grow antlers, many believe they are mainly used in territorial battles between bucks. Some wildlife biologists believe that female deer evaluate a buck’s antlers to assess whether he would be a good potential mate. Antlers have been prized and pursued by hunters for many centuries. For additional information, refer to MU Extension publication G9487, Nutritional Requirements of White-Tailed Deer in Missouri. Often, these objectives are enforced by state regulations or voluntary harvest criteria established by landowners or hunters.

Healthy males maintain their hardened antlers throughout the breeding season (Figure 7). What was the weather in Pretoria on 14 February 2013? Secondly, most bucks are still stressed from the long winter so their overall body is in recovery mode. The goal of using antler criteria as a mechanism for determining harvest is to give young males in the herd the opportunity to mature into older age classes. The mounting points on the heads of deer from which the antlers grow are called pedicles. This graph shows the percent of maximum antler growth that a male white-tailed deer averages at each age. We love them. To achieve these deer management objectives, landowners, managers, biologists and hunters often implement an antler point restriction into their management plan. However, factors such as date of birth and condition of the mother can affect antler development. The composition of the dry matter portion during this stage is 80 percent protein and 20 percent ash (primarily calcium and phosphorus). “Culling” is often done to remove “inferior” antlered males from the population in the hope of restricting the spread of “inferior” genetics; however, controlling or manipulating deer genetics in wild populations is virtually impossible. Within the past decade, many Missouri landowners have refocused their white-tailed deer management objectives to allow more male deer in the population the opportunity to reach older age classes and, thus, the potential to produce larger antlers. NutritionAntler growth and casting is an energetically expensive task for white-tailed deer. When do Deer grow back there antlers? Four of these theories are described below. The mule deer's tail is black-tipped, whereas the white-tailed deer's is not. Figure 8. Figure 3. Antlers reflect an individual’s nutrition, especially protein and energy levels. Recent research supports this particular theory. Tab will move on to the next part of the site rather than go through menu items.

Enter and space open menus and escape closes them as well. Leg injuryAntler deformations can also be caused by leg injuries, which often result from deer-vehicle accidents. Deer antlers can grow as fast as half an inch per day. After the breeding season, cells start to de-mineralize the bone between the pedicle and antler, causing the antler’s connection with the skull to weaken and the antler to fall off. Rear leg injuries coincide with antler deformation on the opposite side  — a rear left leg injury will affect the right antler. I’ve often wondered if there’s a certain amount of days once they start growing until the shedding of velvet. In addition to this, they can also branch out better when they are in their top shape. Antler growth is regulated by hormones, which are controlled by photoperiod (day length). They start mating in fall and two fawns are born usually. Young deer grow their first set of true antlers the first spring after they are born, at 10 to 12 months of age. In the spring and summer a mule deer's antlers are covered in velvet. Figure 4. velvet usually stops growing mid August- early September. This deer conservation guide is one in a series developed jointly by MU Extension and the Missouri Department of Conservation. When you purchase mule deer antlers from some of these fly-by-night shops or individual sellers, you simply don't know what you're getting. Antlers that are shed normally have a relatively flat surface at the base (a), whereas antlers shed with pieces of pedicle attached (b) will often result in injury to the pedicle, one of three main causes of deformed antlers. One of the fastest growing tissues in nature, whether a trophy hunter or not, antlers hold a certain power over us as hunters. Demarais, S., and B. K. Strickland. 1989. 7. A difference of 8 percent and 16 percent protein in a deer’s diet at 4 years of age can cause a 20-inch difference in antler size. To learn more about how antler criteria can be incorporated into a deer management program, refer to MU Extension publication G9480, Implementing Quality Deer Management on Your Property. Therefore, removing inferior antlered males will not change the herd’s genetics. We filmed, via time lapse, the growth of a deer antler after being harvested to demonstrate how quickly it can grow back. Males typically begin growing a new set of antlers in late spring. Young deer grow their first set of true antlers the first spring after they are born, at 10 to 12 months of age. On average, males increase their antler size until 6-1/2 years of age, when antler growth is maximized (Figure 10). Figure 6. During growth, a soft, blood-rich skin called velvet covers the antlers. Figure 2 illustrates the basic terminology for parts of the antler. This process initiates drying of the velvet, which is then sloughed or rubbed off, resulting in polished, hard antlers during the breeding season. 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. When do deer antlers stop growing? This velvet has blood vessels to help the antlers grow. Velvet injuryAs mentioned previously, during the growing phase antlers are very soft and, therefore, vulnerable to injury. Velvet injuries can cause deformations in the hardened antler, including small points known as “kicker” or “sticker” points. However, current research does not substantiate antler size correlating with dominance between individual white-tailed deer. The velvet will fall off on its own, but the process is accelerated by rubbing antlers on small woody shrubs or even tall grass. Their rapid growth and deciduous (regrown each year) nature has made them fascinating for hunters and wildlife enthusiasts alike. When a deer is injured, the antlers fall off rather easily. The musk deer, which are not true cervids, also bear tusks in place of antlers.. Antlers are usually found only on males. Growing antlers are high in water and low in dry matter content. Whitetail deer antlers contain bone with the fastest growing tissues in the animal kingdom. If this were true, females could determine the quality of potential mates by evaluating their antlers. In some areas, they shed off antlers in December and in other areas in April. How Do Whitetail Deer Antlers Grow? Once the mating season is over, the shedding process will begin where the antlers become loose around the base and eventually fall off. Antlers are made up of a honeycombed bone-like tissue. Although this theory may be true, it would mean that females are always defenseless and that males are defenseless once their antlers have shed and during the antler growing phase. JavaScript seems to be disabled in your browser. The black-tipped tailed mule deer has bifurcated antlers which grow like a fork. If a deer is in its best health, the antlers are likely to grow bigger. As the antlers harden and the velvet dries up, bucks will begin to rub their antlers. But one female (doe) in several thousand whitetail does will grow antlers because of a hormone imbalance. They're bones that grow extremely fast outside of a mammals body, and every year they fall off and grow back. Male white-tailed deer commonly establish dominance in the breeding season by fighting with other males to determine strength. The biological mechanism controlling this relationship between leg injuries and antler deformations is not fully understood but is thought to be associated with reallocating nutrients toward healing the leg injury, instead of antler growth. The main factors affecting antler size of an individual white-tailed deer are age, nutrition and genetics. Help improve lives, communities and economies throughout the state.

The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. GeneticsA white-tailed deer’s potential for antler development is controlled within its individual DNA, or genetics, although optimum nutrition is required to express this genetic potential. The factors that dictate year to year growth are the age of the animal, its genetic makeup, and its nutritional intake. Up and Down arrows will open main level menus and toggle through sub tier links. However, one modern species (the water deer) has tusks and no antlers and the muntjac has small antlers and tusks. They fascinate us. What you see on a buck’s head right now, is what you’ll get for this year. 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). Antlers are normally branched (except for spikes), and maturity, good nutrition, lack of stress and good genes determine antler size and formation. Male white-tailed deer with antlers in the velvet stage. While “in velvet,” antlers are particularly vulnerable to injury, and cuts or bruises suffered at this time often result in deformed antlers. And even when minerals are abundant in the environment, much of what goes into antlers is mobilized from other parts of the skeleton. Antlers are among the most identifiable characteristics of species of the deer family, Cervidae, which comprises caribou, elk, moose, mule deer and white-tailed deer (Figure 1). Some velvet injuries may result in an oddly bent antler caused by an injury during the velvet stage that was able to maintain its blood supply and hardened into a polished antler (Figure 9). Sambar: 43 Inches. For the best experience on our site, be sure to turn on Javascript in your browser. Sign in to follow this . I’ve often wondered if there’s a certain amount of days once they start growing until the shedding of velvet. Many landowners are becoming interested in allowing more male deer on their land to reach older age classes and express their genetic potential for antler size. Now during mid- and late August, antlers are hardening. To learn more about how these factors affect deer antler and body size, refer to MU Extension publication G9480, Implementing Quality Deer Management on Your Property. Let’s see how it grows. Antler growth depends on an individual deer’s access to quality nutrition, age and genetics. The antlers are very soft and damage can easily occur during this time period. White-tailed deer antler growth cycle coincides with the breeding season so antlers can be used as individual bucks establish dominance. Typically, only male deer grow antlers.
