How to Photograph a Deer Jawbone for Aging

One of the most important skills for any deer manager involved in a Quality Deer Management (QDM) program is the ability to age deer after harvest. Without knowing the deer’s age it is unfair to compare deer by body weight, antler size or reproductive output. It is also important to know the age structure of …

VIDEO: Jawbone Aging Part 2 – Tooth Wear

One of the most important skills for any deer manager involved in a Quality Deer Management (QDM) program is the ability to age deer after harvest.

Without knowing the deer’s age it is unfair to compare deer by body weight and antler size. It is also important to know the age structure of your deer herd to know where your program is and where it is going to set realistic goals and expectations.

The most commonly used technique to age deer after harvest is the tooth replacement and wear technique. As the name implies, this technique involves two processes – tooth replacement, simply the replacement of teeth over time as with humans, and tooth wear, the erosion of teeth over time.

In part one of our jawbone aging series, QDMA CEO and wildlife biologist Brian Murphy examines tooth replacement to classify deer ages into three groups – fawns, yearling (1.5 year old deer) and adult deer (2.5 or older).

Here in part two of the series, Brian demonstrates how the tooth wear technique can be used to age deer into the older age classes.

The final installment in the three-part series allows viewers to apply what they’ve learned with a jawbone aging quiz.

Estimating Deer Age with Cementum Annuli

The cementum annuli (CA) aging technique is based on the annual addition of cementum, a specialized calcified substance deposited on the roots of teeth in many mammals. Layers of cementum produce “rings” similar to those in trees. A darkly stained ring, or “annulus,” is formed during winter stress, whereas lightly stained rings are formed during …

Like me, deer are slaves to their stomachs, they feed many times each day, and food is what drives their movement. Identifying deer movement patterns results in successful hunts. To …
