A cattle disease, Bovine Viral Diarrhea, which supresses the immune system and causes a variety of symptoms, and significant economic loss globally, including 5000 in Germany where over 500 were killed, was probably spread by vets, farmers and cattle traders according to one of the first research articles published in the new open access journal Heliyon. The authors of the study, from Friedrich-Loeffler-Institute, Germany, say farmers and people who visit farms should take biosecurity measures.
Read these lines from the article and see if it scares you:
Because of its biological and economic significance, an attempt has been made to eradicate BVD in Germany. This has in some farms resulted in a cattle population that has neither been exposed to the virus nor vaccinated, making it more susceptible to infection.
Think of the parallel between this and the movement to eliminate chondro from the Dexter herd. Unknown consequences, for sure!
"an attempt has been made to eradicate BVD in Germany. This has in some farms resulted in a cattle population that has neither been exposed to the virus nor vaccinated, making it more susceptible to infection."
This just means that if your herd hasn't already lived through a BVD infection, then it doesn't yet have immunity.
That's true of most all viruses.
For example, if you haven't already had ebola, then you are more susceptible to ebola than someone who had it years ago and survived, since they now have some degree of immunity.
I wouldn't encourage anyone to run out and get ebola, just so they can work on developing immunity to ebola.
PS. I'm happy that my herd has immunity to the lethal Chondrodysplasia gene.... herds get that immunity by testing and culling any lethal gene carriers.
I fear the influx of Angus disorders, like curly calf syndrome and the other 13 types of dwarfism present in some of them and the Dexters that were crossbred with them. The people who raise those junk cattle are exposing the rest of us.
Why do misinformed people think they are smart enough to pick out a trait they like from another breed and then dumbly believe they can steal that trait without suffering the others.
Just look at the incidence of dystocia due to the oversize calves found in the descendents of the outcrossed cattle that have found their way into our breed. It causes more problems than PHA ever did and runs up more vet bills.
Dexters are famous for their trouble-free births. The cow wanders away from the herd and lies down. She gets up, shakes her horns, and starts licking the calf. Nobody there and nobody needed. Compare that to the slick headed crossbreeds with their fancy regimen of birthing pens with a retinue of people standing by to pull, pull, pull.
It's not the cattle's fault. They didn't do this to themselves. It is misguided people who put their own wants and fears ahead of good sense that did it. If they were so afraid of the horns on the gentlest breed of cattle they should have bought some of the hornless cattle from other breeds instead of corrupting the wonderful Dexter breed.
There is no immunity to this condition. You can't get a shot to make you smart enough not to do this. Some people are just way too much into immediate gratification. They want something, so to heck with how badly they harm the breed for all time.
Once these idiots succeed in breeding the horns off of all our Dexters, the only way we can get them back is to outcross with a different horned breed that the slick head people haven't corrupted yet. Every flaw that belongs to that breed will come along this time, just as it did the last time, when they were outcrossed to take the horns off.
It sickens me that there are people who consciously do this.
The number of dystocia birth losses associated with polled cattle has risen to the point that it could be proper to call it the lethal polled gene.
Think about that the next time you read a web page that brags "100% polled". That's one of the people. The first person who did it might be able to claim stupidity, as in "I didn't know what would happen." The current crop goes far beyond that, to mean and greedy.
