Hello, I just wanted to share that while attending OSU farmed deer program last fall I had the opportunity to listen to Dr Brandt Cassidy (laboratory director of DNA Solutions) on collecting DNA samples. He gave examples of collection methods:
-Hair sample (must contain roots) in a paper envelop
-Antler core sample (drilled from hard antler) in a plastic Ziploc bag
-fresh tissue kept cold/frozen or in 70% alcohol
-Semen straws can be used but must contain semen or cotten plug
I guess you can get DNA from all cells including cells of mucle, bone, White blood cells, skin cells, hair roots, and teeth.
Myself I collected hair samples becuase they were easy to get, easy to store,and easy to ship. Also, I kept an extra hair sample in each deers file for future reference. That may be easier for you than messing with blood, Since they will be down anyway.
Hope this helps and have a great day!
