Feeding antibiotic milk to calves

[it's not over]

What if any are the effects of feeding fresh milk containing various antibiotics to calves.has it any adverse effects on good bugs in the calfs stomach. Does it have any negative or positive effects on calf scour,

Milk containing antibiotics should not be fed to calves it should be dumped in the slurry store !!!

I'd have no problem with giving it to anything bar future breeding stock.

What about colostrum from cows treated with dry cow so?

 

[M-J-G]

If I inject a suckler cow that has a calf at foot it seems to have no ill effect on her calf.

We only use 28 day ab dry cow tubes and aim for a 50/60 day dry period.

The main effect would be the loss of your milk contact.

There's still a withdrawl period after calving though
Isn't the main reason for not feeding antibiotic milk your contract and red tractor?

Yes, 100% agree, but colostrum is a necessity in newborns.

 

[The Agrarian]

Can't be sure about this, but I'd be inclined to think that the digestive system of a new born is not pre-populated with gut flora, and probably take days to weeks to fully stabilise.

Building up Ab resistance?

 

[som farmer]

most contracts have a clause re colostrum, 4 days withdrawal, as said, antibiotic treated milk, should not be fed to replacement calves. The other side, calves need colostrum, which with dc tubes, is a/b. So very probably a grey area, we acidify our colostrum, and store, to feed to calves. A case where not feeding a/b milk, looks good on paper, by a s/mkt nerd, but not practical, concerning colostrum.

As far as thread title’s go this would be better deleted

 

[Fergieman]

Feeding colostrum that is generally past the withdrawal date is somewhat different to feeding fresh treated mastitis milk which is generally only 12hrs after treatment and well within the withdrawal period. I am more than happy to feed the colostrum but all treated milk goes to slurry tank.

we delvo test fresh cows, before putting in bulk tank, it is suprising how many fail, at day 3/4. So where does that leave us ? Also, some young calves, are tested for a/b at slaughter, we found that out, when we had 1 fail, luckily, we were able to show it was an a/b we have never used, perusal of vet/med book, and letter from vet, confirming we hadn't ever bought it.

doesn't say much about the testing

I think there is some research about bench-marking calves fed antibiotic milk which leads to ineffective treatment later, as the later treatment was below the benchmark.

Developing the digestion system of a baby calf is a delicate process and should be treated as such. All whole milk should really be pasteurised first.

In addition:

2. Do not feed waste milk
Waste milk from cows being treated with antibiotics should not be fed to calves, because of the risk of antibiotic resistant bacteria developing. Milk from cows with mastitis often contains large numbers of bacteria and feeding this milk can potentially spread infection from your herd to the calves. Mycoplasma bovis often manifests as mastitis or high SCC in cow and is another reason not to feed waste milk to calves.


How would you fancy a mouthful of diseased milk ?

What rubbish!!

 

[som farmer]

if calves require colostrum, which by definition, is the cows first milk, and that colostrum fails the delvo test, because it contains a/b, how do you overcome that, only those which haven't been treated with dc tubes, qualify, the % of cows not treated with d/c tubes, fairly low ?

Building up Ab resistance?

We had to switch to Tylan because our first-calvers mastitis was resistant to everything else, makes milk powder look f**king cheap really.

Plenty do it, also plenty moan about mastitis!
