Dear Jeffrey:

We have completed processing on the whitetail deer specimen that you submitted on November 5, 2015 for forensic aging. We promised to have the results back to you by March 5, 2016. The cementum-annuli analysis has determined that the age of “Jeff’s 2015 NJ Fall Bow Buck” is 5.5 years. Nice trophy! We will be sending you a paper copy of this result via the US Post Office. If you have any questions, or if we can be of additional assistance, please do not hesitate to contact us. As always Jeffrey, we appreciate your business. Thanks.

JC,
 
Very nice. I hope it really is legit. I told them I thought my 2015 buck was 6.5 based on pics since 2011 and that's exactly what I just got back last week from same place you used - 6.5. The reality is any buck that lakes it past 2.5 in this state may as well be 8.5 they get the best Hunter education in the world here.
 
Congrats again Jeff and it was a pleasure spending that day hunting with you and helping you get that big boy out
Congrats again on an awesome animal.

I have a very high level of confidence that it is, and I don't rely solely on their results. In this case, long before I got their results I did a comparative analysis of the teeth of this buck against several other sets of 3.5 and 4.5 year olds I own. All of the other sets are from other deer taken in the same general area, and all are cementum annuli aged. Several of those cementum annuli results are also confirmed by the fact that the deer were of known aged based on multiple years of trail cam pics. I concluded from my initial analysis their was zero question this buck's teeth were significantly more worn than were the 3.5s I have. So, I had no question it was 4.5 or older. When I compared the teeth to a known 4.5, again the teeth from this deer were noticeably more worn. Accordingly, I concluded on my own, based on the tooth wear and replacement method that this buck was at least 4.5 and most likely older and 5.5. Therefore, as stated previously, I have a very high level of confidence as this buck was aged by two different tooth methods at 5.5.

Nice going Jeff! I also got the email today for my NY archery buck, mine was also aged at 5.5 years old which is what I was expecting based on molar wear and other physical attributes. Any deer 3.5 or older is a trophy in my book, congrats again.

The teeth on the top belong to this buck. The teeth on the bottom belong to a known age 4.5 from the same area.

Yeah the teeth on mine looked closer to those on the top u just showed. I just heard some people question the legitimacy of cementum annuli, but far more have said it is the most accurate. I will continue to use them, I think it's just another piece to the puzzle to fully understanding whitetail behavior and also proves that antler size and even body weight can have nothing to do with a buck's age. Thanks for sharing

The teeth aging method with whitetail is pretty accurate from birth to 3 years old. After 3 years of age, the accuracy drops in a major way to the point it's not very valid (see below).

The percentage of jawbones and dental casts that were correctly aged by age-class is depicted in Figure 1. Eighty-five percent of the jaws and casts in the 1-2 year age class and 73 percent in the 2-3 year age class were aged correctly. Accuracy dropped dramatically in the older age classes.




EDIT: In before the same 2 or 3 posters who attack me whenever I post data from scientific studies of Whitetail arrive.

You are referring to the "classic" biologist method of jaw/tooth/molar aging. Cementum Annulli analyzes the front lower incisors, similar to rings on a tree. I have seen it stated as being 100% accurate. I hope so.
 
BG - with shipping total cost was about $30. A36 - for me it was confirmation that a buck I had pics of as a 5pt in 2011, 8pt in 2012, then rack went real goofy in 2013, was the same buck I shot. That was the final piece of the puzzle of the buck I called "tripod". In 2013 his injured hind leg finally locked at 45 and that's when the rack went fubar. I was never 100% sure they were same buck so if deerage.com confirmed it was 3.5, I knew it was not same buck, but if it was 6.5 or older, I knew it was same buck.

The intel gathered by knowing the age of a buck you perceive as "mature" is invaluable. Older bucks are different animals and behave entirely different from younger bucks. When you kill a buck based on certain patterns and then you substantiate that it might be a really mature buck 4.5 years or older, then it will help refine your hunting techniques for those older class bucks.
 
I agree with Jack. It may not be important information to all hunters but for hunters that target mature age class bucks, it's very useful information. For me personally, I care very little about antler scores, my goal is killing bucks 3.5 years and older. My NY buck is a perfect example of this. He was only a 6 pt, 20.5 in. inside spread, good mass but not going to score very high at all. However at 5.5, this deer was in his prime and likely as big as he was ever going to be antler-wise. To me, taking a buck in this age class is a true trophy and one that I will proudly hang on my wall. Having my deer aged is confirmation that I am field judging these deer correctly and am hunting for them in the right areas.
