The bulls in the record book from the 1900’s and 2000’s all could have resulted from good genetics, excellent nutrition and age. His mainframe from 3.5 to 5.5 years old did not change tremendously despite the addition of significant mass, some tine length, and more overall “character.”. …of growth recorded for the elk is 2.75 centimetres (1.05 inches) per day. When the antlers have reached their full extent, the blood supply is constricted, and the skin, or velvet, peels off, thus revealing the hard, dead, bony antlers produced by the male deer in time for the autumn… His point configuration remained much the same as he added mass each growing season. 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). The average growth of antlers is more than 2 inches per day in an adult buck.

Increasing levels of testosterone, in addition to decreasing daylight hours, are among the major factors contributing to antler growth during the summer months. The third is age. Shortly thereafter, the antler growing process begins again. For most bulls, extra years can mean larger antlers if the nutrition holds up and the previous winter was not too severe. An elk’s velvety antlers are developed enough to harvest when the animal is between one to two years of age. They are capable of breeding at two years of age. Although the antlers are regrown each year, their size varies with the age of the animal in many species, increasing annually over several years before reaching maximum size. Every year bulls that gross over 360” plus are harvested and found to be under the age of seven. Bulls will typically reach their peak antler development somewhere between the age of 8 to 12 years. Deer Antler Growth Cycle. When the new antler comes up they push the old antlers off. 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.

Five-to-7-year-old animals have the largest headgear. Antlers are not horns. Some bucks are homebodies, staying in their 300 to 400 acre home range throughout the year. In the world of the whitetail (and some mule deer and elk), agricultural crops play a major role in nutritional intake. A buck with antler spread well outside the end of the ears is normally a mature or older buck. Without water, quality forage does not grow and antler growth is not maximized. Animals that tend to roam far and wide put themselves through more stress each fall than do the relative homebodies. 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. April through May (Spring) Antler growth begins from the permanent bases on the male cervid's skull. Mature bulls average 800 to 1,100 pounds, stand 5' to 5'6" at the shoulder, and are 7 to 8 years of age. Below we will examine these factors further as well as look at the year to year growth of a couple different bucks and bulls. All of those things were probably present prior to Europeans settling the country. If you do, taking the time to identify a buck’s home range and some of his “personality traits” can make year to year hunting a lot of fun. That is part of what makes each year so much fun.

The genetics they got from their father (sire) and mother (dam) make that determination by the way the genes are passed on from one generation to another. But I would point out that those seem to be the only two of that category. There is one more factor that should be considered with regard to antler growth: individual variation. For older age classes, however, you can forget it. By the age of 6 or 7, a healthy bull can start carrying around a good-size rack, usually with six prominent points on each side.

The only problem with that theory is that magnum bulls are typically not found in museum mounts nor were they found in attics and lofts in barns so that they could be measured once the scoring systems were developed by Boone and Crockett and Pope and Young. Antlers emerge as cartilage, with bone replacing the cartilage from the pedicle up as the antler grows. He thinks that elk conservation has grown elk big recently within the past hundred years and the were no +400 inch elk before elk conservation. We once again fell back on our resident biologist and Director of Private Lands Stewardship, Tom Toman. Antlers will continue to grow each year that the buck lives and will reach its full-size potential until around four years of age. LIMITED TIME ONLY! A genetically gifted animal with a poor dietary intake will not reach his potential. We often see less antler growth after really tough winters as it take quite a bit of energy to regain body conditions which steals some energy that would normally go to antler growth. Keep in mind, many factors play into this creature’s antlers, including their diet and growth rate. The same is true with bull elk. They don’t seem to exist. Limiting hunters means less hunting pressure and more opportunity for bulls to escape the hunters and live another year. Antler growth can suggest a bull elk’s age. Older animals grow bigger antlers.
