Muhammad Kashif The live vaccines colonise the birds for life - you only need one vaccination. You should also vaccinate for MG and MS. MS can mimic anything MG can do. ts-11 and MSH can be used from 3 weeks of age. Immunity may take 5 weeks to develop and you need to not use antibiotics after vaccination.

Have a look at!Pages/Publications/Documents/DOC-Bulletin-2015-02.pdfthere are at least three different responses by flocks to vaccination especially to ts-11 and they are all normal. Perhaps as Robin Achari says it is very dependant on the time after vaccination what you see but serology is useless after vaccination is my conclusion from 25 years experience. If you ...

Abdulcader titres often increase after 40 weeks and can be very high in normal flocks. The only way to investigate if this is 1) Normal - just high titres after 40 weeks or 2) Field challenge (from a variety of reasons, post vaccination antibiotics, infection before vaccination etc) then you should find field strain. So you need DIVA PCR - it will detect field strain if that is the problem ...

Well, I think that killed avian mycoplasma vaccines make humoral antibody. In fact, to get registration, they only have to show production of antibody - from the monograph. It is just sort of assumed that it is correlated with protection. So I agree that they can decrease systemic pathology, tracheal populations, vertical transmission but they don't seem to be able to stop infection or vertical tr ...

Wijaya Saputra Serology is useless after live vaccination (and probably killed MG vaccination). There are too many normal responses and perhaps these are modulated by factors other than mycoplasma - like using LaSota.!Pages/Publications/Documents/DOC-Bulletin-2015-02.pdf See the bulletin. But in Australia nearly all broiler breeders have no serological response ...

David Baquero we have to stop using antibiotics every 4-6 weeks for human health reasons. In the short and maybe medium term it is effective but it may mean the loss of effectiveness of antibiotics for treating ordinary infections in the long term: it is expensive.
