Certainly needs further investigation,hopefully you have reported it to your local Animal Health office......yes?
Interesting. You are right to report it. However I've not seen or heard of TB being like that in deer. Miliary TB ocurs in humans though. I can't tell however, if these lesions are on the surface or deep within the lung. If it was just surface, I'd wonder about lungworm, but it's quite severe. Getting a section done for histology would be great.
Doesn't look like TB to me but I'm far from an expert but definitely something worth getting checked. It would be good to hear the diagnosis when you get it back
This is some form or parasitic infection according to the experts.
If you're shooting badly, you need a new gun. If you're shooting well then you deserve a new gun.
