Dr.m.suresh India's big problem is that they dont have Rispens.

Caecal droppings (yellow pasty mucoid droppings) in layers can be very common, caused by Brachyspira infections. We found them to be present in most free-range flocks, causing 20% drop in production and an additional 10% mortality if untreated. In cage sheds, flies seemed to be important in the transmission of the infection - faeces - flies - feed - and in many tropical countries they have open-si ...

Brachyspira infection causes few signs except egg production drop and diarrhoea and it can respond to acidification of the water (or antibiotics)Get a pig lab to help you diagnose it - they deal with it every day.

We have been examining vaccinated flocks by DIVA PCR and culture recently in Asia. Here we can not find the MG and MS live vaccines in flocks that have had anti-mycoplasmal antibiotics. We typically find field strains (we suspect they are resistant to antibiotics). The vaccine strains are sensitive to all anti-mycoplasmal antibiotics (even quinolones like enrofloxacin) even if local field strains ...

Ganesh Kumar Dahal I am just in Argentina and one vet is telling me how all antibiotics had stopped working on one client's farm and he was able to get control of mycoplasma again by vaccination. Remember not to forget MS as well as MG

Vaccination in an infected environmentAll vaccines take a little while for the onset of useful immunity (save non specific protection from mechanisms like gamma interferon in viral infections). Mareks vaccination becomes more effective with the current vaccines if challenge can be delayed a couple of weeks.Live Mycoplasma vaccines also take 3-5 weeks to generate immunity and challenge needs to be ...

Other myths are emerging.1) ts-11 only works to 40 weeks (of age or after vaccination). This is a misunderstanding of the seroconversion that often takes place after the peak of lay in vaccinated flocks. Studies on these flocks don't find wild strains and there is no production problems or clinical signs. They only thing they seem to be suffering is antibiotic deficiency syndrome. See Barbour et a ...

INTRODUCTION The simplest approach to decrease dependence on routine antibiotic regimes in animal production is to implement alternative methods to control the bacterial challenges that the antibiotics are modulating (and not look at antibiotics as non-specific production enhancers). The chronic nature of mycoplasma infections and vertical transmission in poultry are the reasons for the strategy ...
