Dear Dr. Kashif,
There are many causes of failure of MD Vaccination.
Improper storage of cell associated vaccine in liquid nitrogen ( Tepm. -196 degree C) is one of them.
No doubt MD is a horizontally transmitted disease, but because vaccination is always done in DOC in the hatchery, this is why the commercial farmers mostly concentrating on this part.
The 2nd most important part is the prop ...

Usually commercial broilers are not being vaccinated against ILT. If you are in Karachi, you may visit my lab (MICRO LABORATORIES, Shahra-e- Faisal, 522, Anum Blessings.
Tel. 021- 34385807)
Pl. bring 4-5 fresh dead birds for diagnosis.

Dear Orobiyi Jubril,
Infectious Larynotracheitis ( ILT) is a viral infection and there is no treatment for this. It can be control by vaccination of ILT vaccine in Layers & Breeders during rearing period at around 4-6 weeks & 10-12 weeks of age via Intra Ocular route.

Based on your knowledgeable work, force moulting could be a good way to save the life of egg producing birds during AI outbreak. I do not have any experience in this connection.
Usually I am recommending to vaccinate the flock against specific type of AI with inactivated oil base vaccine for the protection of uninfected birds of exposed flock.
I like to add in your work that durin ...

Dear Authors,Thanks for providing good information to overcome the heat stress in Broilers.Further to this I like to add that supplementation of Sodium Bicarbonate (NaHCO3) @ 0.4% in feed or (0.2% by weight) in water is helpful during heat stress in broilers. Actually panting of birds to fight with high temperature causes loss of Carbon dioxide (CO2) and Respiratory Alkalosis raises pH of blood of ...
