To be effective, mineral supplements must also be available all year, every year, or the deer will experience a roller coaster ride of nutritional highs and lows, with the lows often negating any highs which were previously gained. 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. 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. One of the positive thing about range condition is quite often it can be improved and even controlled some what that is if you take out the drought factor, nothing we can do there. Abscission line at the antler — pedicle interface. During this process, the antlers eventually mineralize and harden. Once the antler is cast, the top of the pedicle can be considered an open wound. Beneath the wound epithelium are cells which will create the antler growth zones. Canadian Whitetail Deer Antlers. A pelletized feed is your best assurance against nutrient and mineral sorting. Deer who grow in tropical countries will have a less than exact deer shedding time. Always remember that minerals first into body growth and maintenance. Antler shape or form, known as conformation, is highly variable and depends on age, genetics, and nutrition. Legal Notices, © 2019 Forest and Wildlife Research CenterProduced and maintained by Agriculture and Natural Resources Marketing. Maintaining a lick costs an average of only $15 per year and. 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. An infant grows on average an astonishing 25 cm (10 in) in … From the time antlers begin growing in late March through the end of April, growth is minimal. n? During summer, deer antlers grow rapidly within two to four months and – according to Peter Yang, PhD, associate professor of orthopedics at Stanford University School of Medicine, they can grow up to 2 cm per day. 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. Mule deer have antlers with beams that sweep out and up, forking twice. Technical problems, contact the webmaster - Last modified: 12/05/2020 04:03:46 pm, Division of Agriculture, Forestry and Veterinary Medicine. In some cases it’s a bit later but not too often much earlier in its life. 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. 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. 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 … Each spring, a buck's antlers start to regrow almost immediately after the old antlers are shed. Extreme care must be taken to assure minerals are in proper balance. Shedding typically takes place in mid-February, with variations occurring by locale. Spongy bone makes up about half the diameter of an average antler (McDonald et al. 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. Ethics Line |
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. 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. Most anyone who has a basic understanding of genetics knows the major flaw with this argument. If a whitetail with 400 inches of antler was a viable model in the wild, it would have a place in the bell curve. The deer appeared to be in poor condition (ribs, hips, and backbone were showing) and upon field dressing showed little or no body fat. Factors That Affect Deer Antler Growth and Development. Antler Size and Determining a Deer’s Age November 14, 2018. Once mineralized, chondroclasts resorb the cartilage, and bone is laid down on the remaining "scaffold" by osteoblasts. 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. Mule deer antlers fork once 6-10 inches from the base and then each branch forks again in the classic mature form. So why the drastic change and why so different from last year? 2005. “DW” was just about done shedding his winter coat, and already showing good antler growth about 1 1⁄2 months into the process on June 25th. The buck came from a good genetic area he was a 6 year old deer but range conditions were poor it had been overgrazed and was in a drought year. As a rule, only male deer grow antlers. A perfect example of this is a deer my dad shot a few years ago. As a biologist, I can’t imagine a better way to manage a deer herd. We love them. 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. In this case genetics are the missing link. Quite often, if the range is in poor condition land mangers have been know to augment antler growth with some sort of mineral supplement. For more details on this process see the review by Price et al. Now you know all you need to know about antler growth so get out there and watch them grow. Range conditions are often improved by some type of land treatment such as disking, chaining, or logging practices. Moreover, when the weather is hotter, the deer antler … What’s happening right now in the atmosphere will have considerable influence on both the quality of horn and antler growth … Trace minerals are those which have been shown to be needed when supplementing an animal’s diet. 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. The annual cycle of antler growth in the mule deer is initiated and controlled by changes in day length acting on several cell types of the anterior pituitary. On July 19th, less than a month later, he was showing incredible growth and was already a very impressive deer! The further south towards the Colorado border you go, the better off you should be for elk and deer antler growth. The seven trace minerals are iron, copper, zinc, manganese, cobalt, iodine and selenium. Too much of one interferes with absorption of another. Most studies have show that a mule deer buck reaches its prime somewhere around 5-6 years old. growth in future years. A normal-sized newborn typically increases in length by 30 percent in the first five months and by more than 50 percent by their first birthday. Antlers. 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. Diagram of a growing antler tip illustrating the main anatomical regions. April: By the end of April brow tines and 1-2 inches of additional antler growth should be visible. Macro minerals are those minerals which are needed in large amounts of the animal’s diet. All pictures, images, & content are owned by MuleyMadness and cannot be used without permission I live in North Central Washington state, Copyright © 2000 - 2020, MuleyMadness.com 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. This means that the deer shed can happen at any time. Antlers reach full growth in late summer usually October. One of the fastest growing tissues in nature, whether a trophy hunter or not, antlers hold a certain power over us as hunters. 2005), although there is considerable variation among animals. 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. The frequency of abnormal points increases with age, and are rarely seen at 1 and 2 years of age. 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. Spongy bone makes up the inner portion and is less dense, softer, and weaker. Advertise With Us. I maintain that in order to truly grow a big mule deer, you have to have all three. 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). What does this mea. 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. Typically, older bucks will almost always have heavier antlers than younger bucks. Range condition—the condition of the range also greatly influences antler growth. 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. It is; if you don’t know what genes are being expressed or can’t control what genes are being contributed by the does (does usually out number the bucks 8 to one on average) then there is no way you are going to be able to get rid of those ‘bad gene’ bucks, unless you eliminate all the does as well. Another factor here is the females in the population. 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. So much of an animal’s life is dependant on its ability to obtain the vital nutrition it needs from the range. The buck had some mass but spread, tine length and main beams were short and the buck squeaked out a mere 160 B&C. 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). We are an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, disability status, protected veteran status or any other characteristic protected by the law. Antler growth stops in August and then the antlers harden. 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. If you are interested in deer hunting and management, this is your podcast! Although described as an abscission "line," the surface of the detached antler base is rough in texture. Certainly there are areas where no matter how old a buck gets and no matter how much you feed him, he’s just not going to be a 200 class buck. The 2019 fall hunting seasons could produce some massive racked bulls and trophy antlered deer. Mule deer can weigh 130 to 280 pounds. Mule deer have no upper teeth, only a hard palate. Before diving into the nitty-gritty of antler growth, we should get one thing straight. Basically, there are three different things that contribute to antler growth and all three are important when considering the whys and why ‘nots’. 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. I’ve seen deer sporting racks that could probably already score in the 120’s by early to mid June. Antler tissue is the fastest growing tissue known to man. The annual casting and growth of new antlers is an important part of the whitetail's mystique. Beneath the wound epithelium are cells which will create the antler growth zones. This weakened attachment combined with the weight of the antler causes it to drop off or be cast. 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. Spongy bone is highly vascularized during growth, which allows the transport of nutrients and growth regulating hormones. When considering antler growth, we must remember that antler growth is secondary to body care and maintenance. 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. Bucks generally have a total of 8 to 10 points on their antlers. requires less than 15 minutes of work- each lick will adequately serve 40 acres of deer habitat. Beneath the velvet and perichondrium lies the mesenchyme growth zone, an area of rapid cell generation and growth. 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. Secondly, most bucks are still stressed from the long winter so their overall body is in recovery mode. In the chondroprogenitor region these young cells begin to differentiate into chondrocytes and to form the columnar structure characteristic of cartilage and bone. Well after the breeding season, cells called osteoclasts de-mineralize the bone along an abscission line where the pedicle meets the antler. You know, the beauties that keep us up at night and we chase in our dreams every fall. Another deer at maturity (C) and the year of his death (D). When it comes right down to it, you either already have good genetics in the local population or you don’t. The resulting surface may be either flush with or extend beyond the burr or coronet. This last year was a great example of extreme antler growth throughout the west. These cell types secrete growth-stimulating hormones that act mainly on the antlers and incidentally on the testes. 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).
