Sheep mastitis

The Maedi Visna virus (MVV) can cause chronic mastitis, several studies have reported an association between presence of MVV in a flock and mastitis. There is a blood test to check whether MVV is present in a flock, if it is then the impact on ewe health is considerable.


Test for Maedi visna virus in your flock

To reduce the risk of MVV:

  • Avoid buying in replacements
  • Test replacements before purchase or buy from a flock where the seller certifies that the flock is free from maedi visna.
