What is Infectious Bovine Rhinotracheitis (IBR)?
IBR is caused by a bovine Herpes virus. It is highly contagious disease which is associated with abortion and inflammation of the respiratory pathways.
Transmission of IBR can be via nasal/oral secretions or from bull semen. Animals can produce a successful immune response but can continue to shed the virus throughout their life, especially during stressful events such as entering a new herd or through calving.
- Airway inflammation and Pneumonia
- Milk yield loss
- Inflamed eyes
Prevention and management of IBR can involve:
- Vaccination (please consult your farm vet)
- Increase biosecurity and only purchase cattle from IBR-free herds
Ensure boundaries with neighbouring farms are secure
NML Testing Services
- Bulk milk antibody ELISA (for dairy herds)
- Individual cow milk antibody ELISA
- Individual cow blood antibody ELISA
- GE antibody ELISA (to differentiate between native infection and GE-deleted vaccines)
N.B. Some multivalent Pneumonia vaccines can contain IBR viral components so be aware of this when using marker vaccines for IBR.
Individual Milk tests can be performed on one milk sample through to a whole herd test. NMR recording customers can request individual cow tests on their normal milk recording samples taking the hassle out of testing. For non-NMR recorded herds we will send kits enabling you to take the required number of samples and submit them to the laboratory for testing.
Bulk tests for IBR can be done on an ad-hoc or quarterly basis. The bulk samples can be tested on samples held in the NML fridge or by requesting a bulk milk sample kit.
To order Individual milk tests for IBR simply ask your NMR milk sampler to fill out a blue form to be included in with you recording samples. For Non NMR herds please call customer services to request sampling pots on 042 96 75 353 or email email@example.com.
To order a IBR bulk milk test please call the NML office along with your Milk Buyer ID on 042 96 75 353 or email firstname.lastname@example.org
To order a blood test just ask your vet to take a blood sample and submit it to the NML laboratories.
Results are available through normal notification methods. These include post, fax, email or online via the milk quality monitor on Herd Companion.
