I think it's better than nothing so am not sure banning it is the best idea, I do however think that you shouldnt be able to just do 30 and then say you're Johnes free because its rubbish. It's like only tb testing half a dozen cows from one group and saying you're clear when the other half a dozen from a different group are riddled with it!

You either do them all. Or see how your milk buyer likes it when you do none.

Just done my RT health review.
I supplied all the figures to the vet.
Could be easilymanipulated.
Always interests me when it's announced the herd is Johnes monitored.
Chocolate teapot.
Vet told me its illegal to knowingly sell a diseased animal ie with bvd or johnes.

I just put down "other" in that column on the computer!
I used to get the milk recorder to put JD at the end of her name and number now I just her to do DNB.
That way everyone can see she's positive on the mating list so she doesn't get bred and see on the close to calving list she needs to go separate and have a kextone.

used to see quite a lot of johnes cows, late 60's 70's, usually CI, then it just sort of went, 2015 had one, that's a long time, but perhaps a few 'screws' were johnes. Quite agree 30 tests are a waste of time, we test the lot, once a year, not sure that's 'perfect', some times a cows a medium risk, then a low, but better than nothing. We mark cows j on cow name, for any med/hi, 3 j's out. Calving wise, any j snatch calf, and only beef. All colostrum from a j cow dumped, we save all the other colostrum, acidify and store, there is a claim, the acidification kills johnes after 3 days, so a safety net, we have 3 medium risk ones, at the moment. We were asked to save some colostrum for a local farm, they were having 'problems' with johnes, not a problem, they brought 72 x 2 litre containers down, and retail milk. Made us think.

not hawthorn. It's called May blossom for a reason (can start in April though).

Nothing - those are all low and not showing any signs of Johnes.

I can't see the top of your page but if they are J5 then they have had 2 positives in 4 consecutive tests at some point so are 'red' and best gone.

The 30 cow test as long as done randomly will give you an accurate indication.
Not knocking the earlier post as it's the testers fault but what is even more useless is giving a farmer a set of results and not telling him how to interpret them.
We can't comment because we don't know what scale they are recorded on the 1 could actually be 100. Or what test was used.
Several of us get ureas in completely different scales.

My understanding also is that if your positive rate is 2-3% it is likely your are johnes free as that is the natural rate of false positives.

But if a herd says they are Johnes monitored I would then ask more about how seriously. We have Johnes tested every cow on the farm from first lactation at least twice in every lactation anything we regard as high risk gets tested more often. Two positives and they are out. Any daughters of positives or any that had their colostrum (we always keep records of what heifers get what colostrum) are then regarded as high risk.

All Johnes positive cows here can't be sold on to another herd, not even a fattening herd that only sells directly to factories only. Straight from the farm of origin to factory only.
We used pool some colostrum a few years ago so a potential problem down the line from that but we should be able to manage our way clear, hopefully
You only built them silage pits 2 years ago. Now going to cubicles?

Four times a year here. So they’re all done at different points of lactation different points when stress may be a factor. Must admit if I was being ultra critical I don’t really see the point of just doing a whole herd once a season either

Sid, I think that proves my point that every situation is different and the impact on the cows is different. In your situation I would be culling on one positive test.
We lost one cow 10 years ago at the time OMSco first started testing, the bulk test showed we had low incidence, so we began bulk testing and putting prevention measures in place.
The best single piece of advice I have had was tackle the one to many spread routes, such as dirty calving boxes, pooled milk etc. first.
Vet said it is easier to eradicate TB than Johnes. WTF
