Not here. I tested one calf for BVD a few years ago. It was negative. Not a bad idea if your herd was exposed.

We test a few every year so they can be sold as bvd free. Never had a positive.

How do i know if the herd was exposed from an outside source?

Think about it from time to time, but with a live vaccination program across the entire herd, I really have nothing to worry about.

Was the calf that tested positive a transient infection or a persistently infected case? If it was diagnosed as PI, then the calf may have exposed other members of the herd with shed viruses.

There is no way to know without testing each member.

It tested as PI but was one of the best calves I had this year. I'm gonna test the herd for sure.

I would work with your vet and test the entire herd.

I do. Would only test if you test them all and plan to weed them out. Had several positives with no symptoms but infect to whole woodpile.

 

[True Grit Farms]

What do you do with the one's that test positive?

I will weed them out for sure. But from what I read some of the pregnant cows that test negative may have a positive calf. And where did i pick it up to begin with. I can test calves I buy, no big deal but testing the cows may not solve the problem.I
The positive one has been disposed of. I will send the buyer a refund.

Why did you test the one infected calf? Or did the buyer test it?

 

[kenny thomas]

The buyer tests every calf.

 

[Bright Raven]

The buyer tests every calf.

Ok. And they identified it as a PI and not a transient infection?

 

[kenny thomas]

The buyer tests every calf.

Ok. And they identified it as a PI and not a transient infection?

Yes, but it weighed 395 and was a #1 calf. Born late and i was selling other calves from there so just took him also.

A PI animal is not necessarily diseased. They have a reservoir of viruses that keep shedding in their body fluids.

All I know is the buyers darn sure don't want one that's PI.

"A PI animal is not necessarily diseased. They have a reservoir of viruses that keep shedding in their body fluids."
BR-could you please explain what you mean by 'not necessarily diseased'?

BVD-PI stands for Bovine Viral Diarrhea-Persistent Infection. BVD-PI occurs when an animal is infected with BVD before birth (in utero). The animal will remain infected with BVD for life and will shed virus continuously.

They have the BVDV in their cells and the virus replicates and sheds in body fluids but they are not exhibiting disease such as conjunctivitis, nasal discharge or pneumonia.
