vaccination in poultry industry

Can you tell me something about thermo-stable vaccine? because,maintaining cold-chain is sometimes difficult here in least developed countries like Ethiopia. so, the role of thermo-stable vaccine is critically important.

Really good & comprehensive article. It will particularly help in effective immunisation of poultry against high peeve lance of disease.

vaccination and biosecurity play any important role in poultry production.If you vaccinate birds that are in a contaminated envroment it will useless as this will increase your mortality and poor performance of the whole flock leading to stunted growth and low returns in your enterprise.Before vaccination make sure you are vaccinating health flock and correct vaccine and correct age of vaccination.Vaccines are not all made for all arears in world but are made based on the epidemiology and out breaks of the disease in a particular area .so dont introduce vaccines that are not a problem in your area/ flock

good article thank you very much on your effort ,but in disease preasure of newcastle in broiler chicks which vaccine they should use

this is a good article that will help the poultry industry to improve in their production. but disease like mareks why can it be given booster.

It is written in this article that Vaccination of poultry younger than 10 days (5-7days) of age cannot be expected to produce uniform or lasting immunity, even in the absence of maternal immunity. Exception is that vaccination for Mareks disease is ordinarily given on the day of hatch.

I want to share one thing that there is a vector vaccine against IBD that is administered in day old broiler chicks.It produces immunity through out the birds life.Even the titre cross 6 at 3rd week from administration.

Here in Pakistan,farmers get vaccination at hatchery,through spray method,( nd+ib) become satisfied that i have done my vaccination at hatchery,but u claim that vaccination b4 10 days does not produce uniform & good immunity,can u add up me that vaccination at zero day is feasible,although soon after vaccination bird have to travel to farm ,in my opinion traveling is great stress for bird, &vaccine done is eliminated during traveling stress,any body can correct my concept,thanks

Vaccine done is not eliminated during travelling. This is the type of vaccine done that shows good or bad results.
Vector vaccine is a special type of vaccine done on day zero. It does not interfere with maternal antibodies.therefore the titre goes upto (6.5) on 3rd week.There is no need to revaccinate the bird throughout its life.
So far vector vaccine of IBD is available in Pakistan.This vaccine has shown tremendous results.This is aqueous based vaccine and given through S/C route.
Vector vaccines of ND or IB are not available in Pakistan. Thats why vaccines against these two diseases have poor results.Out break of ND or IB occurs inspite of spray at hatchey.

i want to comment on things.
1) I am from Nepal and here we vaccinate broiler and layer birds before day 10 against IBH and ND, and in both the cases the number of outbreaks is reduced. what may me the logic behind that??
2) According the author vaccination during outbreaks of ILT and Fowl Pox are beneficial. I have never practiced vaccination during such outbreaks but in case of ND, live F or B1 strain oral vaccination is very effective and popular here. why vaccination of sick birds produces immunity?

Vaccination with B1 or lasota works on the principal of receptar blakade at the cellular level and is quite effective in controlling the Newcastle diease. Vaccination with a F Pox vaccine during a F pox outbreak is also effective in reducing the intensity of the diease.

Its a nice and informative article, hope to have more of such articles in future.

Would you please comment the followings:

1. What is the role of disease spreading by back yard poultry (esp NCD)?
2. Can we reduce outbreaks with NCD vaccination to Backyard poultry?
3. What could be the storage temparature of NCD vaccine, is it differ with different manufacturer or same for all?
