Bovine Viral Diarrhea (BVD)

Bovine Viral Diarrhea (BVD) is a highly contagious and economically significant disease that affects cattle worldwide. The virus can cause a wide range of clinical signs, including respiratory disease, diarrhea, abortions, and immunosuppression. BVD can also lead to reduced milk production, weight loss, and poor reproductive performance.

BVD Sampling in Northern Ireland

In Northern Ireland, BVD sampling is an important part of the national control program. The program is designed to identify and eradicate BVD from the cattle population.

Who Can Send BVD Samples?

• Veterinary practitioners
• Farmers
• Livestock markets
• Abattoirs
• Other authorized personnel

What Samples Should Be Collected?

• Blood samples: Blood samples can be collected from individual animals or from a pooled sample of animals from a single herd.
• Ear notch samples: Ear notch samples can be collected from individual animals.
• Semen samples: Semen samples can be collected from bulls.
• Milk samples: Milk samples can be collected from cows.
• Fecal samples: Fecal samples can be collected from individual animals or from a pooled sample of animals from a single herd.

How to Collect BVD Samples

The specific method for collecting BVD samples will vary depending on the type of sample being collected. However, there are some general guidelines that should be followed:

• Always wear gloves and protective clothing when collecting samples.
• Collect samples from animals that are showing signs of BVD or that have been exposed to the virus.
• Collect samples from a representative population of animals in the herd.
• Label samples clearly with the animal's identification number, the date of collection, and the type of sample.

Where to Send BVD Samples

BVD samples should be sent to an approved laboratory for testing. In Northern Ireland, there are several approved laboratories that can test for BVD.

Cost of BVD Testing

The cost of BVD testing will vary depending on the laboratory and the type of sample being tested. However, the cost is typically between £20 and £50 per sample.

Benefits of BVD Testing

BVD testing can provide a number of benefits, including:

• Identifying and eradicating BVD from the cattle population
• Reducing the economic impact of BVD
• Improving the health and welfare of cattle
• Protecting the livelihoods of farmers

Frequently Asked Questions

• What is the difference between BVD and IBR?

BVD and IBR are two different diseases that can cause similar clinical signs in cattle. However, they are caused by different viruses and require different control measures.

• How can I prevent BVD in my herd?

There are a number of things that you can do to prevent BVD in your herd, including:

* Vaccinating your cattle against BVD
* Testing your cattle for BVD
* Isolating sick animals
* Practicing good biosecurity measures

• What should I do if I suspect that my cattle have BVD?

If you suspect that your cattle have BVD, you should contact your veterinarian immediately. The veterinarian will be able to collect samples for testing and recommend a course of treatment.

• How long does it take to get BVD test results?

The time it takes to get BVD test results will vary depending on the laboratory. However, results are typically available within a few days.

• What are the consequences of having BVD-positive cattle?

The consequences of having BVD-positive cattle can vary depending on the circumstances. In some cases, the cattle may need to be culled. In other cases, they may be able to be treated and remain in the herd.
