Strange antibiotic failures...

Are you with muller by any chance?

Hmm, interesting. Had our first ever dairy notified ab failure around new year with a follow up from the Dairy Inspector. We still to this day do not know how the failure came about.

A neighbour here had bother a few years ago with the tank test showing antibiotics, turned out to be mouldy meal which the mould was similar to penicillin or something along those lines

Penicillin is a Mycotoxin after all - Just a helpful one.

We have had some strange results with muller recently! We have not had a failure for many years! I can't even remember the last! Then 6 months ago we got a failure but by then they had already taken the following days which passed! We are in robots so shouldn't have human error unless imputed wrong, but that would have failed the next day as well. Then about 2 months ago we had another!!!! We asked for a breakdown (which came back with a drug that we have never used) again they had taken the next day which passed! But by then I done a delvo on day 3 which failed!! Done nothing more and following days passed! Doubting delvo and muller testing now!!!!

We had a sample back in September with a AB failure, a FPD of 541 and 0.000 urea and fat and protein both 0.2-0.3 different from the previous test. Tested the next load of milk and it was fine and hadnt tubed/treated any cows for 3 weeks before. Our milk buyer ignored it as the tanker was fine.

Had something similar with them myself a couple of years ago, a couple of AB failures at a time we were sure nothing could have got in, failed one day then fine the next only to have the same a few weeks later. My thoughts were that they must have mixed our samples up but they said that wasn't possible, it was our milk and had AB in it, I was equally sure there wasn't AB in our milk.

A few weeks ago we had rapidly soaring bactoscans, couldn't find a problem so called dairy engineer in but found nothing. Funnily enough I heard the other day that others had been having the same problem, they'd had a tanker not washing properly but were unwilling to admit it. Dairy engineer tells me he knows of similar problem with ARLA and they wrote to all affected farmers to explain/apologise.

It's not a good situation to be in but I'm afraid I don't have faith in Mullers milk testing.

I really don't know why we all don't take a sample and put in freezer for this exact reason

Are you using Cepravin in dry cows?

Also do note that the Delvo test is overly sensitive so will fail milk that is legally fit for sale.....

Have you tried the Cowside kit? its a competitor to delvo
