Tb test

Bugle boy

Hi guys,
Haven’t used this before so hope I work it ok. I had a herd test and had a bull and cow inconclusive. Retested, bull clear cow wasn’t so she went down and I’m locked up now. 2 of my neighbours went down also, rampant around here seemingly. Thing is, I had to have another test before my two clear tests. That (other) test came back clear. The cow that went down, showed up clear in factory as did the bull, he was going anyway his time with me is up. Anyone ever in this senario before?
Thanks in advance

Just because the cow has no visible lesions in the post mortem doesn't mean she doesn't have TB. There is a difficulty in seeing lesions which may be very small and not visible to the naked eye but may still be present.



And there is a period of time where the reactor will react but not show up visible lesions or positive culture tests after infection. Even the culture tests aren't 100% accurate as they only take a sample from a small portion of tissue and the site of the sample might be a distance away from the lesion.


There is a change in restrictions being lifted after 2 clear tests round here anyway. You get a 3 month window after the second clear test to sell any stock you want to sell and then you're restricted again until you get another clear test and a further 3 month selling period and the a 3rd restriction before you're cleared to sell as normal.

Thanks for that. After my second clear test, hopefully, my restriction is lifted. That’s what I was told anyway, but they make the rules up as they go along.

They'll do a check test after 6 months and then back to annual test.

I doing the fool all year with testing here, some pain. I think it's only one third of visible cases of tb are positive when they are slaughtered.

Id actually 4 cracking heifers bought off a friend who was out of test, had his annual herd test last week and failed it. Said it was the first time in 19 years.... 2018 is some gowl of a year.

Any harm to ask what areas above posters are in?

Mooooo

New rules after second clear test seem to be you can sell for 3 months, after that it'll be only calves under 6 weeks can be sold until another clear test is had which can be done 4 to 9 months after the second clear test.

Don't worry from personal experience they'll charge those rules next week and the week after that and again the week after that.

Do you know if these calves are eligible for export. I'm hearing that there is an issue with calves from what was described to me as retention test herds and these calves cannot be exported.

Not sure tbh, a share of the calves I sold last year after that point went thru thw mart so i assumed they were ok at that point?

When I find out more I will let you know.

There are a few neighbours affected with TB in my area.
My test was clear back in July and my next test isn't due till July 2019. Is there a chance that i will be called for a test sooner than that if TB is in my area?

If they are on your bounds ditch and gone down anyway recently you will more than likely have to test. If they went down the same time as you did your herd test you are prob ok

There are various reasons why reactors don't lesions. The No Visible Lesions stats are only really administrative tools. IMO they should never have been made public as they generate the expectation that all reactors should show lesions on PM.
The one-third is the usual proportion I've heard quoted that show lesions too, if a vet/farm is generating a greater proportion then questions are asked as to why. This is its best use.

Basically, you've enough to worry about so don't get caught up uselessly on NVLs.

If you're contiguous, bounding any affected farm, you will be tested again before your herd test

If a neighbour you share a boundary fence with has TB you will have to do another test.
And your herd will be locked up until your test is clear.

I think that applies when your last test was more than four months ago.

Got word back that my cow showed up no visable lesions.

We had our annual test back in Feb all clear. Neighbors went down so we got word that we had to do another test in June all clear. Another neighbor went down, test again last week by the department this time all clear again.
Basically you'll be lucky to get away until June.

If a neighboring farmer has more than 1 reactor then you will be tested once its 4 months since your last test. 3 different neighbors adjoining my land are down at present so for the last 2 years I have 7 test (all clear TG). 1 of the neighbors is a dealer who has a place on a long lease & regular reactors. I sent a 10 year old cow to the factory last year, her card was covered in stamps, TB tested 28 times & 5 Blood tests.

I got a letter 10days ago that the neighbor had gone down in TB test. My last herd test was mid August. Does this mean as I am within 4 months of testing that I will not be locked up and will be ok until my annual retest in August???
It never mentioned on the letter that I’d have to test but I assumed that would follow.

Same in Clare. Pockets of reactors appearing in various locations. Vet thinks increase has to do with a lot of forestry being harvested disrupting badgers habitat.

There's different rules for different areas but I would be fairly sure you will be testing early next year as you're contiguous to a restricted herd.

I don't know, j. The rules here are different to the rules elsewhere because they still haven't control of the outbreak here after 3 years.

One letter won't leave you restricted, but if a couple of others go down in the general area you will be.

Once results have gone through the system your next test is schedules on AHCS. You will not be notified until it comes close but its there and your vet can check it for you.
