Early in October we undertook our annual bTB test and were relaxed going into reading day as we are a housed herd with no wildlife carriers (as far as we know) within 5 mile radius, nothing bought in within last 18 months and then from Denmark and are in a supposed clean area with no pre movement testing
So the surprise was great when we had two “reactors”
These have been duly culled as per rules and lo, no lesions or sign of bTB.
However Welsh Government have a policy of blood testing all animals over six months if two or more reactors show on the skin test. This will be a gamma interferon test that captures all micro viruses including Johnes so we have been told to expect “false positives” which will also be culled regardless. Potentially we could lose a large number of cows and heifers despite our Johnes management plan.
Further we cannot restock until we have a clear skin test so a minimum of 60 days of lost income from any milkers taken.
Sheer madness causing unbelievable stress
