Dear Wijas,
Thank you for your question. Actually, as we do have other diseases are challenging the flocks, it is difficult to say this signs or other are related to AI, we are also having challenges of ND and IB variants.
Here some signs we believe to it close to the AI problem:
Layer and breeder:
- Drop in production specially when the production going up to the peak and it will be severe when it comes with ND or AI.
Broiler:
- We see yellow material in bifurcation.
- Also we see high mortality and the % depend on what other diseases are playing a role at the same time.
We are strongly advicing farmers to get blood serology tests or FTA card for PCR samples to be sure about what is going on more that clinical signs to avoid miss diagnostics.
Regarding the blood samples we are advising the following:
- Not less that 25 samples on the day of the clinical samples.
- After 2 weeks another 25 samples after you test them for AI or any other disease you are expecting.
Please feel free to ask if you need any further information.
All the best.
Bakri

Dear Wijas,
my opinion is we shall use mg live vac for protection birds and checking AI field H9 genetic for matching the vaccine used or using the homologous vaccine, possibly H9 itself can affect production and mortality even free mg.
Dr Bakri:
Thank you for sharing your expertise. I wonder if you could put me in contact with an expert on Avian Influenza and other main avian diseases in Sub-Saharan Africa Countries or West Africa Region.
Thank you so much.
Fernando.
