Feeding antibiotic milk to calves

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,

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.

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 ?

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 ?
 

Get ready for pest monitoring, advises PGRO

The Processors and Growers Research Organisation (PGRO) has issued new advice to help growers understand the importance of measuring pest populations before any decisions are made on insecticides. Charlotte Cunningham reports. Ahead of the trapping season, the PGRO has produced a new masterclass video to help growers understand how to trap and assess pest populations. The key advice is that using a range of preventative tools will be crucial for farmers looking to reduce cases of pea and bean weevil, pea moth, and silver Y moth this spring, while finding more sustainable ways of farming in line with new agricultural policy, according to the PGRO’s research and...
