Even at two and a half years old, ongoing data suggests a buck's antlers have likely only grown 25 to 35 percent of their full potential. This first set is usually a spike or fork hornâ. Moose antlers are usually paired and shaped like the palm of a hand with outstretched fingers, thus the expression palmate. Elk antlers can grow as much as 1 inch a day! Pedicles become visible as buttons on males at about 4 to 5 months of age (Figure 3). The primary reason for this is that the amount of daylight is much less than what it will be in June. The reverse is also true. With the boost in testosterone, deer antlers can grow up to two inches per week, and in some cases, bull moose can put on a pound of bone per day during the peak of their growth cycle. Recent research supports this particular theory. Type 2 or more characters into the input search below for suggested results, use up and down arrow keys to navigate through suggest box. Figure 5. One of the most common causes of nontypical antlers happens when the buck or bull damages the pedicle or base where the antlers grow. 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. The antlers that are being produced on deer farms grow much, much larger. They will grow a new set of antlers yearly. The following photos illustrate antler growth for 1 buck from 26 March 1999 through 15 September 1999. It may be hard for novice hunters to determine an age of a buck by its antlers because they grow at different rates depending on the health of the habitat. Antler Development in White-tailed Deer: Implications for Management. 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. How long does it take for a buck to form hardened antlers? In fact, deer antlers are among the fastest growing tissues in the animal kingdom, growing as much as 1/2-inch per day during peak antler growth. Huge antlers also make bucks stand out among their whitetail peers. Moose are the largest living member of the deer family (Cervidae) and fittingly bear the largest set of antlers. Growth of antlers in female whitetail deer. “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. Age, nutrition, and genetics are among the essentials that play a significant role in how strong and fast the antlers grow. A doe is a female deer. The main factors affecting antler size of an individual white-tailed deer are age, nutrition and genetics. That’s why you see the biggest antlers after a deer reaches 4 ½ to 5 ½ years of age. 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. - body growth and maintenance takes precedence over antler growth. Photo Gallery From Ons To Booner Deer Hunting Realtree O. Deer Age Plays a Factor in Antler Growth. While rare, it happens. However, these injuries can develop infections, causing potential health problems. The following photos illustrate antler growth for 1 buck from 26 March 1999 through 15 September 1999. it is now that the velvet will begin to dry and falls off. Antler size is dependent on age, nutrition, and genetics. Pedicles become visible as buttons on males at about 4 to 5 months of age (Figure 3). A deer’s antlers can grow very quickly. Most of the time, these antlers will be spongy, but on rare occasions, they can harden the same as male antlers. Some exceptional antlers can be found on deer in the “middle-age” age structure (3.5 to 4.5 years). Dry matter content of hardened antlers is composed of about 60 percent ash and 40 percent protein. They are typically unbranched and permanently established on the animalâs head. Biologists have determined white-tailed deer antlers can grow as much as one-half an inch (1.27 cm) per day during their peak growth. Factors that Determine Antler Size (listed in order of importance). A deer’s genetic potential is controlled by the genetic makeup of both its parents and can affect antler shape, composition and size potential. It has to be said, stags are far less impressive when they’re without their charismatic antlers. Antlers are made from bone, and they develop from the pedicle on the frontal bone of the skull. When a buck is 1-1/2 years of age and grows his first set of antlers, average he will have four points, a 16 mm or 5/8-inch antler beam diameter (~ dine diameter), and just over an 8-inch outside spread. These defects are permanent antlers and do not shed like other deers. Signal of male qualityBecause they are grown mainly by male deer, antlers are thought to serve as a visual cue signaling health and genetic quality to female deer. Several theories attempt to explain the evolutionary purpose of antlers among some male members of the deer family. White-tailed deer may grow deformed antlers as a result of an injury. However, variation in antler quality among individuals may not be a good predictor of mating success. 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. Figure 8. A red stag starts growing antlers around 10 months old, and for each year the antlers elongate and thicken. However, one modern species (the water deer) has tusks and no antlers and the muntjac has small antlers and tusks. Antlers develop into every size and shape. Deer first begin to grow antlers between early winter and late spring. Antlers reach full growth in late summer usually October. Most importantly, the animal has to have adequate nutrition. 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. The main reason that deer grow antlers and one of the reasons that it is the male of the species that grow them is to attract a female deer for mating. In late August or early September, growth is completed and blood ceases to flow to the antlers. You do need to cover him for tetanus. Velvet is considered to be one of the fastest growing mammal tissue on earth. Healthy males maintain their hardened antlers throughout the breeding season (Figure 7). 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. All deer species shed their antlers in winter, after a … Bucks refers to a male deer and it is prudent that it should have strong antlers as the mating season approaches as they use them to fight off the competition. Genetics, nutrition and age have much to do with antler growth. Until a buckâs bones are completely developed, body development will always take precedence over antler development. During this time, the soft growing antler is covered with hairy skin, called "velvet". Hunters may see a buck’s best antlers anywhere from 5 1/2 to 8 1/2 years of age. The buck will help it along by rubbing his antlers on trees, shrubs and saplings. Oxidized blood/local plants - antler color depends partly on the amount of oxidized blood left over from velvet shedding and partly on a chemical reaction between the blood and sap from plants on which the antlers are rubbed. A What Makes a Big Buck? In bucks 7 years old and older, antlers mass often increases, while overall length of the main beam and … There are also deer, which have extremely rare genetic defects that cause a set of antlers to grow. Figure 2 illustrates the basic terminology for parts of the antler. 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). Of course, the amount of antler growth depends upon nutrition, genetics, and age. To understand the role that genetics plays in antler development it is first necessary to understand the contributions other factors make to a buckâs antlers. Antlers have been prized and pursued by hunters for many centuries. They are one of the fast-growing tissues in the animal kingdom. Bucks usually sport their largest sets of antlers when they’re about five to six years of age. Use Esc key to go back to input search field. Even bucks with healthy diets still lose those minerals in their body while growing their antlers. Antler growth is regulated by hormones, which are controlled by photoperiod (day length). While “in velvet,” antlers are particularly vulnerable to injury, and cuts or bruises suffered at this time often result in deformed antlers. As is the case with most deer species, the whitetail buck grows a new set of antlers every year, and the antlers will typically re-grow bigger every year until it passes its prime at about 5-7 years of age. Without adequate nutrition a buck with the genetic background to become the world record whitetail buck might be less than average. Now the antlers can have a spread even with or outside the ears with decent mass. Male deer begin growing their first set of antlers at about one year of age. In bucks 7 years old and older, antlers mass often increases, while overall length of the main beam and tines declining with each consecutive set of antlers. The mounting point where the antlers attach to the head is called the pedicle, where they break off. During this time, two stumps of bone pop out from the deer's pedicles, wrapped in a thin layer of velvet skin. Figure 4. In fact, deer antlers are among the fastest growing tissues in the animal kingdom, growing as much as 1/2-inch per day during peak antler growth. Figure 10. Most males maximize their antler size at 6-1/2 years of age. That’s why you see the biggest antlers after a deer reaches 4 ½ to 5 ½ years of age. According to the data made from an observation of whitetail deer, almost 90 percent of bucks that lack brow tines by the age of 3-4 years had spikes when they were a year old. Bucks under two years usually sport small, spiked antlers, although the size of a buck's antlers is not a determinant factor of its age. Genetics play as much a part of a mule deer's life as they do … For additional information, refer to MU Extension publication G9487, Nutritional Requirements of White-Tailed Deer in Missouri. 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. Velvet injuries can cause deformations in the hardened antler, including small points known as “kicker” or “sticker” points. 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. Harvesting “management” or “cull” males is a common deer management technique. The antler growth cycle is driven by photoperiod (day length) and hormones. Let’s learn something more about velvet – What is velvet. Female caribou also grow antlers, though not as large as those grown by males.

Do Female Deer Have Antlers: Reasons why Not All Female Deer Have Antlers though all male Deer Have Antlers Except Those Who Are Castrated at Their Tender Age?. 1989. The antler growth cycle coincides with the breeding season, so that males have hardened antlers for fighting other males, subsequently establishing dominance and breeding privileges (Figure 5). Major threats to whitetail deer … It S In The Teeth How To Tell Age Of A Deer . A doe is a female deer. 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. Antlers are unique to cervids. They also grow back the same shape, or close to it, every regrowth. Of course, the amount of antler growth depends upon nutrition, genetics, and age. The whitetail male deer usually reach adult size when they are 5 or 6 years old. This often happens at an early age or right after the animal has shed its antlers in the spring. During this process, the antlers eventually mineralize and harden. In this process, soft tissue is converted directly to bone by the deposit of minerals within the cartilage and blood vessels in the developing antlers. Antler mass and length increases with age until bucks reach 6 to 7 years of age. The skin or tissue that develops at the top of the pedicel reacts to hormones in the deer body and actually causes an antler to grow/develop. The composition of the dry matter portion during this stage is 80 percent protein and 20 percent ash (primarily calcium and phosphorus). Antlers are branched paired structured extensions to the anterior bone of the skull in mammals from deer family (Cervidae). An injury to the body can also influence antler growth because energy is used to grow or repair muscle or tissue before it is used to grow antler.
