Spongy bone is highly vascularized during growth, which allows the transport of nutrients and growth regulating hormones. Shedding typically takes place in mid-February, with variations occurring by locale. You know, the beauties that keep us up at night and we chase in our dreams every fall. They will have achieved 90 to 100 percent of their antler growth potential, and they can have highly stained tarsal glands during the rut with the stain extending well below the tarsal gland. 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. Deer who grow in tropical countries will have a less than exact deer shedding time. Plenty of moisture has the grass growing quickly and food will be plentiful this spring and summer for optimal antler growth for the mule deer as well as the whitetail bucks. The snow storm that just hammered the I-80 corridor, shutting it down for several days, has the area from Rawlins east all the way to Cheyenne sitting in much better shape than it was a month ago. 5 Deer Antler Shed: Climate. Mule deer have antlers with beams that sweep out and up, forking twice. This weakened attachment combined with the weight of the antler causes it to drop off or be cast. 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). Last year, Arizona had an extremely dry winter … I often here the argument that if we just eliminate those ‘bad gene’ bucks or those. Quite often, if the range is in poor condition land mangers have been know to augment antler growth with some sort of mineral supplement. If you are interested in deer hunting and management, this is your podcast! ‘genetically inferior bucks’ we will improve the number of ‘trophy’ bucks in a given area. This means that the deer shed can happen at any time. All summer long we’ve been watching bucks grow antlers. A similar situation occurs in the other direction, in that Sitka black-tailed deer antlers resemble those of white-tailed deer. These examples of antler conformations and their gross and net Boone and Crockett scores are all deer harvested in Mississippi.A) typical: gross 173 7/8, net typical 172 0/8B) typical with sticker points: gross 192 3/8, net typical 171 4/8C) drop tines: gross 214 1/8, net non-typical 201 3/8D) double main beam: gross 192 4/8, net non-typical 178 7/8E) palmated: gross 190 4/8, net non-typical 175 5/8F) cluster points: gross 312 4/8, net non-typical 295 6/8. If a whitetail with 400 inches of antler was a viable model in the wild, it would have a place in the bell curve. There are two types of bone within an antler, spongy bone and compact (cortical) bone. Essential minerals alone are often poorly palatable. We’ve been watching them grow and grow, hoping against hope that this will be the year. Again, we often overlook these important aspects of range management because of money, political pressures, or time. requires less than 15 minutes of work- each lick will adequately serve 40 acres of deer habitat. I maintain that in order to truly grow a big mule deer, you have to have all three. I would guess that most general season areas on average harvest bucks between 2-3 years old. Stages of antler growth.A) one day after antler shed,B) 15 days after shed, scab still attached,C) 30 days after shed, scab is shed (A, B, C same animal),D) about three months after shed by different animal,E) about five months after shed antler growth is completed, with one additional month used to complete hardening and drying of velvet (D and E same animal), andF) hardened antler with shreds of dried velvet on a third animal. Whitetails, mule deer, elk, moose, caribou, and many other antlered animals across the globe are part of the same deer family, known as Cervidae. Extreme care must be taken to assure minerals are in proper balance. Another factor that can affect the antler shed is the climate of the area. Privacy Notice | They fascinate us. Lastly, whitetail does need to be 6 to 8 months old in order to breed, but mule deer does have to be 18 months old to reach sexual maturity. If a buck is mature, look for a substantial frame at this time of year. Antler tissue is the fastest growing tissue known to man. This is perhaps more evident and easy to show on a small scale such as a small ranch or a certain drainage rather than over hundreds of thousands of acres. Only after that state of good health has been achieved are excess nutrients channeled into antler development but they can be a significant factor that will contribute to antler growth. Antlers reach full growth in late summer usually October. Another deer at maturity (C) and the year of his death (D). 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. Basically, there are three different things that contribute to antler growth and all three are important when considering the whys and why ‘nots’. Factors That Affect Deer Antler Growth and Development. An infant grows on average an astonishing 25 cm (10 in) in … Typically, older bucks will almost always have heavier antlers than younger bucks. Abscission line at the antler — pedicle interface. A) showing the rough texture due to attenuated spicules of bone, B) showing a line flush with the antler base, C) showing a line that would have extended from the base into the pedicle, and D) showing the likely effect of a brain abscess or bacterial infection (note dried puss at arrow). June: Antler growth should increase dramatically this month, so look for all the main points on the antler to be growing by the middle to end of the month. When considering antler growth, we must remember that antler growth is secondary to body care and maintenance. This last year was a great example of extreme antler growth throughout the west. Compact bone forms the outer shell of the antler, and its greater density and stiffness provide strength for fighting. As a rule, only male deer grow antlers. Some deer antlers exhibit annual variation in conformation, and a deer's last antler set may be quite abnormal. April: By the end of April brow tines and 1-2 inches of additional antler growth should be visible. Trace minerals are those which have been shown to be needed when supplementing an animal’s diet. Given the liberal harvest that most states employ it’s highly unlikely that general open seasons are going to have many or should I say a majority of older bucks harvested on any given year. As you may already know, all male deer (family Cervidae) grow antlers.They are used for warding off predators, sparring with other deer, and they attract female deer (doe) during the mating season (like a male peacock's feathers). Macro minerals are those minerals which are needed in large amounts of the animal’s diet. May: Look for visible G2’s and antler beams should be at about half their final length. Ethics Line | During this process, the antlers eventually mineralize and harden. By Dan Carlson Hunters understand that the impact of weather on big-game animals is crucial year-round and not limited to the last four months of the year. In Mississippi State University, there is a deer lab. Although described as an abscission "line," the surface of the detached antler base is rough in texture.

As a biologist, I can’t imagine a better way to manage a deer herd. You also mentioned that the weather plays a role in both horn growth as well as during the hunting season. Mule deer can weigh 130 to 280 pounds. This is largely due for the simple fact that game managers don’t have the ability to isolate and control certain genetic traits expressed by antler growth. Antlers are normally branched (except for spikes), and maturity, good nutrition, lack of stress and good genes determine antler size and formation. However, several states are now starting to look at managing their ‘limited’ harvest units to some age class on buck deer. Macro minerals include calcium, phosphorus, potassium, magnesium, sodium and sulfur. In no particular order they are; genetics of both the buck and the doe, age of the buck, and condition of the range or the quality and quantity of available green groceries. Mule deer have no upper teeth, only a hard palate. The seven trace minerals are iron, copper, zinc, manganese, cobalt, iodine and selenium. 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. Maintaining a lick costs an average of only $15 per year and. Contact Us | 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. Some may argue that one is more important than another and in some instances that may be the case. Beneath the wound epithelium are cells which will create the antler growth zones. Antler growth stops in August and then the antlers harden. This is very true. In this case genetics are the missing link. Antler Size and Determining a Deer’s Age November 14, 2018.

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. Age–age is the easiest to control at least in theory. Bucks generally have a total of 8 to 10 points on their antlers. 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. Most anyone who has a basic understanding of genetics knows the major flaw with this argument. Spongy bone makes up about half the diameter of an average antler (McDonald et al. I’ve seen deer sporting racks that could probably already score in the 120’s by early to mid June. These cell types secrete growth-stimulating hormones that act mainly on the antlers and incidentally on the testes. Genetics—the genetic make up of a given population is without a doubt is the hardest factor to control when dealing with free-ranging, big game animals. In some cases it’s a bit later but not too often much earlier in its life. Outside the fence where survival must be earned, a 400-inch whitetail is the inferior deer. According to Missouri scientist Dr. Grant Woods, a buck’s rack will show most of its points by mid-June, though tine length is typically less than half developed at this time. If certain areas are exceeding the age class objective, more permits are usually given, if they are not meeting this age class objective permits are usually reduces the following year(s) until age objectives are being met. If range conditions are poor, animals are usually in poor health and body condition is usually poor and antler growth will never be maximized under these types of conditions. A note on supplements can be broken into two groups of minerals, macro and trace. The enlarged and columnar chondrocytes then begin the process of mineralization. Media | Growth rate slows dramatically during late summer while mineralization of the antler is completed. Another factor here is the females in the population. Continuing to feed deer in the fall and winter is also important to support the nutrient requirements of all classes of deer to support their body weight and body condition to continue to have a successful program the following year. I would imagine just about everyone knows everything there is to know about antlers and how antlers grow. 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. The annual cycle of antler growth is regulated by changes in the length of the day. The factors that dictate year to year growth are the age of the animal, its genetic makeup, and its nutritional intake. If you want to have older bucks you simply control the harvest rate such that you limit your take on younger deer. There is a wide range of mineral supplements available on the market today. Too many animals, whether wild or domestic, will result in decreased antler growth and could reduce the animal’s fitness and reproduction rates as well. This graphic from the Mississippi State Deer Lab shows the entire antler growth cycle…here we focus on spring growth, what is happening right now: New antler growth resumes about 3 weeks after (old) antler drop, on a scab that has formed over the pedicles. Most everyone realizes that genes and nutrition play a major part as well as age but for those of you who don’t—here you go. 2005), although there is considerable variation among animals.

As a hunter these are the areas I want to spend my time and money on. Mule deer females usually give birth to two fawns, although if it is their first time having a baby they often only have one fawn. Antlers. Many of these are managing for a certain age class of bucks which is determined by the average age of buck taken through harvest and tooth analysis. Mule deer antlers are bifurcated; they "fork" as they grow, rather than branching from a single main beam, as is the case with white-tails. Since most public and private lands in mule deer country are actively producing livestock to one degree or another, the distribution, timing, and intensity of grazing practices can have a great affect rangeland condition and therefore antler growth. But now’s the time to stop hoping and start measuring, because antler growth is nearly finished throughout almost all of whitetail country. Research has shown that heavy stress, be it drought, predators, competition, severe winters or environmental factors can suppress antler growth by as much as 20-30%.

Another reason antler growth is slow in coming during April is the lack of quality food because spring green-up doesn’t normally come to the no… The three factors that affect antler growth are well documented and have been studied for centuries. 2005. growth in future years. X-ray of cross sections at the antler base showshows the range of variation in relative amount of spongy (dark center) and compact bone.A) average composition,B) minimal spongy bone, andC) maximal spongy bone. Antler shape or form, known as conformation, is highly variable and depends on age, genetics, and nutrition. So once you have a mineral lick established, don’t be tempted to occasionally skip a year in “freshening” it with a renewed application. All pictures, images, & content are owned by MuleyMadness and cannot be used without permission We love them. Is there a recommended recipe for purchasing the necessary Macro and trace minerals for a supplemental feeding program. n? I have to bite my tongue most of the time when I hear this. Always remember that minerals first into body growth and maintenance. One common thread with mineral supplement is people expect to see overnight results when it often takes years to really make an improvement with your population. The resulting surface may be either flush with or extend beyond the burr or coronet. It is just a two-week difference but this actually leads to higher birth rates for the overall population of whitetails.

There were more than just a handful of 200 class ‘muleys’ and a grundle of 400 class bulls harvested last fall. Beams and tines may grow a quarter-inch or more per day, the process driven by a buck’s hormones and the photoperiod of the summer days. The whitetail deer are also shedding their winter coats but don't have as much hair as the mule deer have , so they don't appear to look as shabby. Range condition—the condition of the range also greatly influences antler growth. 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).
