Mycoplasma vaccibe
- Thread starter HarryB97
- Start date
If that’s the one I think our vets used to have to get an import license to bring it in. I used it a few years ago when we reared a lot of calves. They had quite a severe reaction to the vaccine. From memory 48 hours of 40degrees plus temps. I stopped using it as I felt i wasn’t gaining anything. Although my in-laws who are dairy farmers. Started vaccinating the cows with it and felt it showed some improvement in the following replacements that were born. Unfortunately there is no magic cure for M. Bovis. It’s a vicious thing when it takes hold in a group of animals.

We used to use a mycro b vaccine but found it knocked them about too much, have used the zoetis mycro b this winter so far very happy with it, they have to have two injections but neither have upset the calves, wouldn’t know they’d had an injection, and so far haven’t touched a calf! Had a huge outbreak of mycoplasma earlier in the year so hopefully this will make a lot of difference!

I use it.had a bad go a month ago thought it would be mycoplasma but it came back as RSV .the lab results showed very low mycoplasma so the vaccine was doing its job.
It is hard on them but nothing you can do about it

I get passive immunity from it into my calves because I use it when I’m drying off my cows, I’m having great success with my calves that are being fed colostrum from vaccinated cows

What did you do for the RSV?
We're they not/out of vaccination?

Intranasal same as I used on the spring Calvers an I've not had to Jag any of them so far.
It was bang on the middle of the cover so not sure what's gone wrong.
All bought in. They all have an intranasal vaccine and bavalto 4 so don’t want to vaccinate more but we do get sudden pneumonia deaths and some really aggressive quick pneumonia cases

Is Bavalto 4 the two injections 3 weeks apart?
When do you give them that? Presumably the intranasel is given soon after arrival
Intranasal is given before they arrive. The Bavalto I give once they have been here 3-4 weeks then the second dose at weaning.

Not possible to give the Bovalto too young?.
Ours are intranasel when arrive. Then first bovalto at about 8/9 weeks and 2nd 3 weeks later. So all vaccinations are utilised.
Just wondering about going earlier with the bovalto, protect against a wider range earlier

I give myco-b to the cows to pass immunity on to calves.
Has your vet spoken about why myco might be affecting the calves? Are the calves coming from a few sources or a single farm? If those farms are keeping any calves on themselves, are they having problems with myco or pneumonia?
My understanding is that an infected cow is brought in, which goes onto infect the entire herd. Calves can then get it through close contact with the cows or from unpasteurised or waste milk. Some herds can be infected but the bacteria stays as subclinical and never affects them, whereas others can have frequent/severe outbreaks of one or a few of the illnesses it causes.
Good nutrition, ventilation, milk feeder hygiene, viral pneumonia vaccines like bovalto, disease status (BVD free etc) and stress can all minimise the risk of myco pneumonia, but you could have just been unlucky to buy calves from a farm that unfortunately has a myco infection that doesn't just stay subclinical - like other people on this thread. Could you have bought an infected calf in the past and the myco spreads at your's through batches? Or could you be repeatedly buying in infected calves? If it's the latter, might be best to talk to the seller. If they're having problems too, them vaccinating their dry cows would help your job and save you the cost of another vaccine, and one that might knock the calves

That's good advice
.The calve with mycoplasma would had brought the infection with in onto your farm. It can then affect close contact animals.
We rear in pens of 3. Usually if one has mycoplasma, one more of the 3 would suffer (don't recall ever all 3 succumbing).
Imo the cost of vaccinating against it would out weigh the cost of an occasional calf with in. It is just another risk of buying calves through market.
Just best to keep a close eye out for the signs - head tilt the main. Isolate and hit hard with Draxxin.
