Does anyone know how the age is being determined for the cwd testing? How accurate is it???
If it is the same as with TB testing it is done at the Rose Lake facility using tooth wear.
Well the age and TB results shows up at the same time. Not sure where the testing is done. Is the tooth wear the visual look or where a tooth is pulled and cut?
DNR Lab does it by visual look.
I never followed the aging process via teeth inspection. Is it normally pretty close say plus or minus 1 year?
I ask because I dropped of 4 heads for testing and some of tbe ages are coming at a complete surprise.
Lots to unpack here, but glad you're interested in aging.
Tooth replacement is pretty darn accurate. That means a trained inspector should not misjudge a fawn (age 0) or yearling (age 1).
Tooth wear has some inaccuracy, but unless you pay for cementum annuli, it's all you have to go on. The one buck I sent in for cementum annuli returned a result of 3YO, confirming what the DNR check station inspector said (along with several respected members of this site), based on wear.
I agree with what many respected posters have said recently -- there is no age:size correlation for does. Some are small and some are large, but it's not a predictor of age.
If you're talking bucks, then I think you need to gather samples from your own area, gather weight, tooth wear and possibly cementum annuli results and determine what each age class looks like. I personally feel the commonly accepted aging on the hoof definitions are off by one year for the ground I hunt in Livingston Co. That is, the given descriptions on the QDMA poster for a 2YO (body shape and antler size) are actually 3YO in my area. I am sure this is not unique to my experience.
What did you drop off?
what are the ages, and why are they a surprise?
I used my new jawbone extractor for the first time this weekend.
These are 3 does. Two were 110-115# and one was much smaller. Noticeably smaller. Didn't ever weigh it, so I guess we'll never know (wish we could have now), but I think it would have been 90# max. These are dressed weights.
I think they are 5YO, 2YO and 3YO (top to bottom), but I might be a little aggressive with the top one. Just wishful thinking because I have never killed one that old .
We'll see what the DNR Lab says. Courier should be dropping them tomorrow...
Ok heres the deer. The bucks were shot after rut. No dressed weights. Clean boneless meat was 57lbs 8pt 54lbs 6 pt. 8pt
Aged at 1.5 yo. For 8pt. 4.5 yo 6pt. Our group figured both at 2.5
The does no dressed weights. But clean boneless meat was 38lbs and 41lbs.
Doe one aged 2.5 y
Doe 2 aged 8.5 yo
