No Jim, the yearlings lose the tusks just like kids lose teeth you can just go out in the bush and pick them off the ground.
Biggest I ever had was 90lbs,world record (which I have seen in person) is 220 Kg for the pair.
Wow, didn't know that Bill. Curious, what would a full grown tusk measure out to in length, and what would it weigh ........ on average ?
