What is ADAM?

ADAM (courtesy of Joe Brownlie and Richard Booth, RVC) is an easy to remember acronym on the steps required to eliminate and protect against BVD entering your farm.

The four step process

  1. Assess the herd
  2. Define the BVD status of a herd
  3. Action plan for control of BVD
  4. Monitor progress

How do I assess the herd?

Look at your Biosecurity measures and consider the 3B’s (Buying, Borrowing and Boundaries) in areas of; disease history, vaccination programmes and the risks of disease on the farm/entering the farm. If you feel all these areas are satisfactory, then proceed to step two -defining your herd status.

If, however any of these areas require action, seek advice from your local veterinary practise who can advise you.

How do I define the BVD status of a herd?

Take a sample number of young stock to establish your BVD status, test between 5 or 10 animals that are 9 to 18 months old by; tag & test or blood testing. Dairy producers can opt for a bulk milk sample.

What is my action plan for control of BVD on the farm?

If BVD is not present in your herd, look at your Biosecurity measures and consider the 3B’s (Buying, Borrowing and Boundaries) in preventing BVD introduction.

If BVD is found, screen by tag & test and remove all PI’s as soon as they are found. Eliminate them by culling immediately. After your final PI discovery, tag & test all calves for one year after. Any more PI’s that are subsequently found, then tag & test all newborn calves for 1 year thereafter.

How do I monitor progress?

Be relentless and vigilant in your Biosecurity. Repeat Step two to retain BVD free status (every 7-12 months for young stock). Consider joining an accreditation and surveillance programme.
