For cost of BVD HerdCheck Dairy surveillance scheme please contact the NML office on 01902 749920. 

Please note that testing will also pick up Border Disease Virus (BDV)

Why test your herd for BVD?

The signs of Bovine Viral Diarrhoea (BVD) may go unnoticed on your farm if you have animals infected with the virus. Equally, if you don’t have BVD present then your herd will be at risk from infection and needs to be protected. This service offers a dynamic picture of the BVD status of your herd by assessing both the levels of the virus and the immune response to it.

What are the benefits?

Determining which scenario your herd falls under for BVD status will help assess the need for biosecurity measures, vaccination and further monitoring that are most suited and therefore most effective for your herd.

What is involved?

Quarterly BVD virus tests will be scheduled on spare bulk milk samples that have previously been collected by the tanker driver, that are held within the NML fridge, so there is no need for additional sampling. Where multiple tanks are sampled on one farm, either each sample will be tested and the extra samples charged for, or a composite sample can be provided by the farmer for testing. To complete BVD HerdCheck Dairy surveillance, a minimum of 10 blood samples are required, from animals between the ages of 9 and 18 months old. These samples must represent the management groups on your farm. Additional blood samples over the 10 per year will incur additional costs of £4.24 per sample.

Please ensure that you have discussed BVD surveillance with your vet to make sure this scheme is right for your farm. Your vet’s details and signature will be required on your enrolment form. Once we’ve received the form, we’ll schedule the testing for your bulk milk samples on a quarterly basis. The blood samples can be sent to us at any point in the year, but we would recommend you send them in as soon as possible. The status of your surveillance can be viewed on Herd Companion at any time.
