I had a thought about the spread of CWD the other day. What do deer breeders do with bucks that don't meet their standards? Lets say they breed a proven buck that has a huge rack to doe X whose buck fawns all have huge racks. Out of this union comes buck Y that the breeder realizes will never reach the potential he was bred for. Still good, but not great. What does he do with the inferior buck? No ones going to pay to kill it. It costs the breeder to feed it, so he is losing money. How does he try to make some of his money back? Does he sell buck Y to a landowner that is trying to improve the genetics of the herd in his area by bringing in new genetics? The breeder pops out the ear tags, loads buck Y into the trailer and takes it to its new home. They chase buck Y out of the trailer onto his new low fence/no fence home free to roam the entire area spreading the CWD he was infected with while at the breeder's facility.
One the other side of the same coin is doe X. She has been a proven producer except for buck Y. She has the big rack genetics but she is getting a little older and is fighting a little too much with the subordinate does that are trying to take her place as the big momma. Same scenario, private land owner wants to improve the genetics around their area, buys doe X, pays cash, doe X slips through a hole in the fence right into a trailer, she is whisked off to Sunshine Happy Acres Farm where she is set free to spread the gift of her superior genetics and CWD, both of which will keep on giving to future generations long after her death.
When I look at maps of CWD where there are what seem to be random outbreaks found just by luck (road kill sample in Arkansas) I wonder what the vector was for the spread. The more I think about it the more I wonder if the ForChevDog critter hasn't spread a lot of CWD to low/no fence areas.
But how does the deer breeder get around the required inventory done by the Department of Agriculture? What happened to buck Y and doe X? No paper trail of transfer so that must mean the deer died at the breeding facility. Don't they have to get the head tested for CWD? Sure, but who verifies the heads being tested actually came from the breeder's facility? Perhaps the heads to be tested came from that random rifle shot you heard last night or more likely, as happened in Michigan, the breeder simply went to the local unlicensed butcher and took a couple of heads off his pile.
I have to quit having thoughts.
