Hi all,
I'm after a bit of opinion/experience of johnes control.
We supply omsco and they would like us to put in place a johnes control strategy.
After a chat with the vet we decided to blood test our dairy herd, two cows came back positive, both around 250%.
All the rest are very low, both cows have been bought in , one around 4 years ago (from a large herd in looe of some dosh but that's a different tale!) The other 18 months ago from a small herd.
The older one is the best of the bunch we had in, always holds and has nice heifers, the last one born over the weekend, I let her lick it off gave it some saved clean colostrum and took it away.
The first of her heifers should be calving in now but has lost her calf, there is another one somewhere around 12 months now this one, I'm pretty sure the first two would have suckled her.
After a bit of reading up I think the two cows will be going as soon as possible which seems to be about two weeks.
Should I shift on her progeny too? What have others done in this situation?
It seems you can't test until they are two years old so if its gone as it should just before calving.
We have been pretty well closed other than these so I think we shouldn't have a problem once they are gone?
The other younger cow has been difficult to get in calf and is now going back quite fast , looks like a picture of early stages so I think the test is reliable.
Next problem is we've just gone down with tb after four or five years clear, so 60 day testing makes johnes testing difficult
Cheers
