I'd like advice regarding an identified inconclusive reactor

Hi
 
I recently had the annual tb test done on my cattle and the results showed that there was one reactor and one inconclusive reactor. The reactor was sent off several days ago to be slaughtered. However, the results of the lab testing showed that the bullock had visible lesions. Does that mean now that the inconclusive reactor on the farm will also have to be culled? I can't understand why because there was hardly any difference between the size of the top and bottom lumps on her and I thought she would get another tb test. However, I am sure that because the reactor was showing visible lesions, she will have to go also. She is due to calve in a few days and is one of my best in the herd. Any advice about whether she will get another chance to pass the tb test? How will the calve survive?
 
Is it possible that she can be taken away prior to her calving? If not, how long after she calves, will she have to leave the farm?
 
Thanks

You will need to get Animal Health to explain. I am not sure if you are in England, Wales or Scotland and procedures may vary. Sadly this policy is a sledgehammer to crack a nut. The rules are being increasingly tightened for cattle owners. In many other countries, including some of those often quoted as being TB free, if any animal proves to be a reactor or lesions are found at slaughter the whole herd is depopulated - thankfully not generally practiced in the UK (unless reactors are over a certain number) - yet.

THE AHVLA sent a letter to state that the reactor had visible lesions. However, I can't understand why the IR also has to go. Can't she be re-tested instead because she was hardly showing anything? They say that she has to go as well, I don't know why.

Hi Guest, really sorry to hear you have had a reactor and IR. You will need to contact Animal Health so they can advise. You should have their details on the correspondence you will probably have received regarding testing or your vet should be able to let you have details.
 
It is well known that the test is not that reliable, identifying both false positives and false negatives.
