Antibiotic failures.

Not sure not had any experience of it thankfully.
Had a mate fail last year had the call very quickly after the tanker left his place at 3am may have been coincidence tho.

Had a 2am phone call from fonterra once my heart sank. Turns out the chiller on the 2nd vat failed and they couldn't/wouldn't pick it up was only a few thousand litres so wasn't a big deal but I didn't sleep for the rest of the night....

Had a few inhibs failures over the years and bypassed quite a bit of milk that was too warm. Twice I had a dead bird in the milk vat, the first time it was in the vermin trap on the pickup hose, the second one was floating on the top of the milk when I opened the vat door. Not a cheap exercise for the farmer.

Cheese boys I agree. My experience is with liquid milk. No way you can ask for a retest on anything like FPD, (which is a faulty test anyway) BF, SCC etc. when the milk is already sat in Tesco's fridge before you're told there's a "problem"

Perhaps not on the same sample but you could get a test on the sample the day before and the day after, just arrange it through NML or via your buyer.

We were once informed some days later of a fail, I was so convinced it wasn't ours (we'd not given any milkers ab in months and nothing cassock recently) I asked for a test to find out which ab it was, turned out it wasn't any! If I'd just ruled over and taken there word they were waving a £14,000 bill in my face

How could you get a test on a sample from the day before ?

If the test the day after is fine for, for example FPD, would they ignore the fail?

Saw a thread on here that mentioned a "rogue" 10% BF test-bet they didn't get paid for a month's supply at that rate!

The point I'm making is that the tests that you get paid on, give you no chance to question the results. No control sample for you to get tested, the Dairy has little real scrutiny on the quality of their sampling & testing procedures (as per above post) yet farmers seem to accept it? FPD test is a prime example as milk straight from the cow can fail, but the "industry" still use it.

Image buying a tractor then saying you're not paying for it as it failed the dyno test you did and telling the seller they can't see the test result or do a test themselves as you've paid someone to destroy the tractor-and they have to foot the bill for that as well!

There's no reason whatsoever why two samples can't be taken every time and one left with the farmer in case he wants to get a check test done.

we have had the report back from lab, tetradelta, multiject, and one i have never heard of.
Tetra delta, been unavailable for 10/12 months, multiject, last purchase in jan. Been using ubrolexin LA, and ubro red DC, neither of which could have caused this failure. 1 new mid lac cow, coming from a once a day, herd, with 5 others, tested 'marginal' fail on delva test, and, having come from mkt, day after sale, milked at mkt, gave b-all, anyway.
Subject to vendors vets, confirming vendor, had not used those tubes, how did we end up, with a positive a/b result ?
Further, milk buyer, has said, they have had a spike, in failures ! Where does that leave us ? Haven't been in contact, yet, with buyer, awaiting confirmation from vendors vets. Anyone had similar experience, and how did you resolve the issue ? Our last failure, 2yrs ? ago, we really couldn't explain, and, as no relief milker, couldn't blame him, but very unlikely to have been us, but took the hit, without questioning.

Is this the same milk buyer you had your bacto issues with ?

So the 6 cows that gave a marginal fail. Only the one was purchased. Appears a strong coincidence.
What delvo test did you use. Talking with my fil the delvo he uses for individual cow sampling is different to the one used for bulk sampling.

yes, but we did find the cause of that, though, only by accident. But, it does make you think, what checks do the buyers do, to test the accuracy of NML, or other, lab ? Or is it a case of ' no point, usually works in our favour' !!!!!! It's the same with FDP, that test, isn't 'licensed' for that, but, the bf, pro, bacto general test, measures that, as well, and considerably cheaper. Perhaps, we ought to be asking questions, most of us farmers, just bend over, and take the caning !!!

6 cows from 1 sale, all delvo tested, as soon as we knew a 'fail'. Buyer, came out, and did his test, passed, before pick up, standard millwood test, and as cow probably only gave 7/8 liters, after arrival, and only 2 milkings in tank...........?
 
Laughed out loud when I read that!

Current situation is the farmer has to believe/accept whatever the Dairy says. (Which. looking on here isn't always true)

How's that going to be any worse if the farmer pays a lab to analyse a "control" sample?
I could have bought the control sample in the local shop or milked a single quarter on a cow into the pot.

sounds to me like it's not your sample..... We had an incident where the tanker drivers brought the wrong stickers to our farm for the sample bottles. When we started getting results back like 5.2 BF and 4.1 protein we were pleasantly surprised with our Holstein ladies, but we did ring the dairy and suggest that the next farmer alphabetically who has a jersey/grazing rat herd might be a tad disappointed with THEIR results!

Just have barcoded sample pots from the Dairy that close with a seal that has to be broken to open (like a plastic milk bottle)
Tanker driver takes two samples and if there's anyone around asks them which one they want to keep

or even the other way round, the whole job, is done on mutual trust, which is fine, but how many people handle that sample ? bulk tank to lorry, lorry to collection point, collection to lab, finally, in the lab, handled by ?many in there, with the best will, many delivery drivers, are poorly paid, and have no interest, in the job, likely to be the same, in the lab.
We had a case last year, AHP were going to prosecute us, for failing to state a calf had been treated with a/b, sold at market, picked up in abbattoir, the drug used, zactran, we have never used, and our vets confirmed they had never supplied it to us, 'oh, must be a mistake, fine', the worrying bit, this was 8/10 weeks, after calf had been killed ! So, as they were so 'open', re mistakes, they must occur, and yet, we do not usually challenge, just bend over !!!!!!!

Surely is a test and process is UKAS accredited there will be quality assurance data being taken and you as a farmer could request this at any time? If it isn't UKAS accredited... that could be a bit of an issue if you were to be taken to court I guess.

FPD always rears its head this time of year. I remember farmers on here saying to restrict cows drinking water around milking (which is illegal and has no effect so don't do it!). At some point somebody has to investigate why some farmers see a plunge in FPD around this time of year... particularly for grazing cows.
