Shortly thereafter, the antler growing process begins again. The rate of antler growth varies according to conditions, but may be as high as six centimetres (2.5 inches) per day in mature stags living in good conditions. Specifically, growth centers around the changing light across seasons. Minerals work like spokes on the wheel of a bicycle. Over his career as the wildlife biologist at the Comanche Ranch in southwest Texas, he’d spent a lot of time and the ranch’s money on such efforts. He was now a typical 5X6. Donnie Draeger used to believe in culling deer to improve antler genetics. Deer have no control over the growth of their antlers, instead relying on a synchronization with nature. … Read More. … Read More. Photo credit: Candiss Ager . Deer require a diet rich in protein, phosphorus, calcium vitamins. Instead, the removal of the best bucks merely affects the genetics of the deer that are still on hoof, the standing crop so to speak. Liveweights, growth rates, and velvet antler measurements were recorded for three cohorts of red deer (Cervus elaphus L.) stags (n = 97) from 3 months to 3 years of age and for one of these cohorts (n = 36) to 5 years of age to provide benchmark data. 6).In the first month to 6 weeks, the branches of a regenerating antler form (Fig. Most bucks will have 8 to 10 antler points when they reach maturity, but there are often deer that have non-typical antler development which results in more. During the Spring and Summer months when bucks are growing antlers, fawns are nursing and does are producing milk, deer crave and need high amounts of protein in their diets to maintain their health and to maximize body and antler growth. For more on the role of nutrition, see the section on Mississippi’s Lower Coastal Plain contains the lowest quality habitat, while the Delta region features the highest quality habitat. While this particular buck is in the Kerr Wildlife Management Area Deer Pen Research Facility, its antler development is representative of whitetails throughout the Texas Hill Country. The factor responsible for stimulating antler growth is insulin-like growth factor 1 ('IGF1'). As you can see his antler size has made a dramatic jump since June 15, and in the next few weeks his antler growth will continue rapidly during the peak growth period of mid-June to mid-July.

Fecal samples were collected every month for a period of eighteen months from male sambar deer in different stages of the antler growth cycle, feeding in the wet patana grasslands of the park, and the fecal testosterone level was estimated by radioimmunoassay. This was one of the greatest increases in antler growth I’ve witnessed in 40 years of photographing whitetails. For example, during the spring there is more daylight, which triggers an increase in testosterone. First, the idea that deer antler spray contains a meaningful amount of IGF-1 is completely ridiculous. The size and formation of antlers vary widely among deer in general. Then the results of a years-long scientific culling study at the ranch started to become available. Deer antler velvet also contains growth hormones, including Insulin-like growth factor I (IGF-1 or somatomedin C) – a hormone that’s produced in the liver as a response to growth hormone stimulation. Calcium, Phosphorus and Magnesium are the three most common minerals in an antler, so when choosing a mineral, make sure you’re using a complete mineral that offers all of the various minerals important for antler growth, like Antler King® Trophy Deer Mineral. The body uses glucosamine to manufacture glycosaminoglycans that are found in cartilage tissue. While the rate of antler growth is affected by nutrition, the actual causative mechanism is not known.

This factor is responsible for the release of sufficient quantities of growth hormone in the body. White-tailed deer antler growth usually begins during the month of March or April, and by August or early September antler growth has ceased. Antler growth depends on an individual deer’s access to quality nutrition, age and genetics. Within a month, the first tine or brow tine will have begun to form or split off. Below is a shed found this past season and the horns from that same buck harvested a few months later. Then the results of a years-long scientific culling study at the ranch started to become available. Antler growth is extremely rapid-an adult red deer can produce a pair of antlers weighing approximately 30kg in three months, and involves both endochondral and intramembranous ossification. Bucks who aren't meeting their nutritional needs may suffer from shorter, less complex antlers. Today’s photo shows what he looked like on July 1. You’d probably find more IGF-1 in a glass of milk. Donnie Draeger used to believe in culling deer to improve antler genetics. Ten animals were randomly selected from each antler stage for the experiment.

High-grading bucks on a property, however, will not change the genetics of a deer population. Approximately a month later, the second tine (G2) will have begun to form. The timing of the peak of IGF1 production is regulated by day length but the key factor influencing the amount of IGF1 production is nutrition. Deer antler velvet may be a natural source of hormones for those seeking aid to muscle growth and development. Antler growth begins by a bud forming on the pedicel. Antlers elongate with a typical S-shape growth curve (Fig. The antler’s growth cycle typically starts in spring when a buck is about age 1.

A video timelapse of a whitetail buck growing a big set of antlers throughout the summer. Buck at 4 1/2 years old–164 B&C. IGF-1 doesn’t last very long in water (unless it’s frozen), so how it’s supposed to remain stable after being sat in a bottle for months on end I have no idea. 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. Exploding Antler Growth. This may happen simply due to a lack of easily accessible food sources, it can occur from a deer eating the wrong types of food. Older animals tend to cast and clean their antlers first. However, it seems likely that the influence of nutrition is mediated by hormones. Male white-tailed deer will often grow "buttons" as fawns. Figure 3. Antler Growth.
