Two other proven techniques - examining tooth replacement and wear on deer jaws and annual growth ring aging - provide more accurate estimates of an animal's age. The bulls in the record book from the 1900’s and 2000’s all could have resulted from good genetics, excellent nutrition and age. Adult elk weigh 600 to 800 pounds, and adult cows typically weigh 400 to 500 pounds. 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. The buck or bull's energy is focused on growth. The factors that dictate year to year growth are the age of the animal, its genetic makeup, and its nutritional intake.

Each antler grows from a point in the skull called a pedicle. This buck’s frame remains remarkably similar from year to year. As a general rule, though, large antlers come with big bodies and old age. 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). After a male (Bull) moose reaches his prime the antlers start … Were there 400 inch elk back then? In fact, antler growth is one of the fastest known types of tissue growth in mammals, and a deer’s antlers can grow at a rate of ¼ inch per day. Yearlings normally have a pair of single spikes, while bulls with three or four times on each side of their antlers are typically two years old. The individual variation comes into play here as well as the genetic makeup of the animal. Antlers. But I would point out that those seem to be the only two of that category.

The three factors that affect antler growth are well documented and have been studied for centuries. Genetic antler anomalies such as a mature bull elk that remain 5x5s, eight-point whitetails, or 3x3 muleys typically occur due to genetic factors. Antlers emerge as cartilage, with bone replacing the cartilage from the pedicle up as the antler grows. I don’t think the hall of fame would be calling. The factors that dictate year to year growth are the age of the animal, its genetic makeup, and its nutritional intake. Counties that have historically produced Boone and Crockett class animals are assumed to have some superior genetic qualities, but strong genetics do not always spell big racks. They fascinate us. goHUNT is a registered trademark of goHUNT, LLC. Of the 34 white-tailed deer biologists surveyed to test this method, 60% failed to correctly age known-age jawbones that were 2 years old or older. Elk have two large, permanent incisors in the front of their mouth by the time they are 18 months old. Animals that tend to roam far and wide put themselves through more stress each fall than do the relative homebodies. From a logical standpoint there should have some super big bulls before the era of Conservation (1900’s and early 2000’s) since there are a couple of things that usually lead to bigger antler growth. Checkers may be a great game but checkerboard-like land ownership patterns are often not so great for wildlife management or public access. Some elk bucks grow antlers with up to 10 points on each side, weighing up to 40 lbs., and measuring up to 5 ft in length. Mature bulls average 800 to 1,100 pounds, stand 5' to 5'6" at the shoulder, and are 7 to 8 years of age. Monsoon season officially starts about the 4th of July which would leave at least 4-5 weeks of growth remaining before the more mature bulls start shedding. LIMITED TIME ONLY!

If there are good groceries, both body size and antler growth will reflect excellent conditions for the bull. Below we will examine these factors further as well as look at the year to year growth of a couple different bucks and bulls. Rough estimates of deer age, such as whether the animal is mature or juvenile, can be obtained from overall body development and antler growth.

The areas that are well known for producing trophy quality animals have one major factor in common: productive soils that produce quality forage year round. This buck has some extremely unique genetic features. Individual deer and elk exhibit personalities as variable as that of people.

The Wisconsin Department of Natural Resources (DNR) is now accepting public input on […]. Without water, quality forage does not grow and antler growth is not maximized. The highest-scoring and lowest-scoring bucks in each age class will still be rare compared to those with average scores, but their actual score potential will be higher. Elk Antler Retention is Testosterone-Driven. As you know, elk antlers don’t change much after the bull dies, so there should have been more winter kill, cripple loss bulls and others that would have been found from earlier days or even in archaeological digs.
