For sampling, the tissues of the brain, trachea, lung, caecal tonsil, liver, kidney, spleen, heart, proventriculus, intestine, and thymus were fixed in 10% buffered formalin.
Diagnosis: The pharynx has 6 teeth with a lateral plate on each side and the proventriculus extends about fifteen segments with approximately sixty muscle bands.
The samples collected from the dead birds included tracheal swabs, cloacal swabs, caecal tonsils, spleen, brain, proventriculus and Payer's patches.

Next, the animals and their organs (yolk sac, heart, gastrointestinal tract [GIT], duodenal loop with pancreas, proventriculus, and ventriculus) were weighed using a scale (WeighMax[R] W-3805-100G, China) with a precision of [+ or -] 0.01g.
Haemorrhages at junction of proventriculus and gizzard were observed (Fig.
Significant differences in proventriculus were observed among the varieties at 12 weeks of age where Mushki variety had the maximum (5.180.7g) and Lakha variety had the minimum (4.10.5g) weight, whereas, non- significant differences were observed in proventriculus at 15 weeks of age.
After the birds died or were euthanized, we collected tissues aseptically from the brain, trachea, lung, kidney, spleen, heart, cecal tonsil, liver, leg muscle, intestine and pancreas, and proventriculus for virus recovery.
