Question:
"Linear haemorrhages between proventricular glands" is the diagnostic significance of which of the poultry diseases?
"Linear haemorrhages between proventricular glands" is the diagnostic significance of which of the poultry diseases?
Show Hint
Hemorrhages in the proventriculus of poultry are a major red flag.
Remember:
- Hemorrhages at the tips of the proventricular glands $\rightarrow$ Newcastle Disease.
- Diffuse hemorrhages throughout the proventricular mucosa $\rightarrow$ Highly Pathogenic Avian Influenza (HPAI).

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Many viral diseases of poultry produce highly characteristic gross lesions on post-mortem examination.
The proventriculus (glandular stomach) is a primary target for vascular lesions in specific systemic viral infections.
Step 2: Detailed Explanation:
Let us analyze the characteristic lesions of the listed diseases:
- Newcastle Disease (ND Ranikhet Disease): Velogenic viscerotropic strains of Newcastle disease virus cause severe vasculitis and necrosis.
A classic diagnostic finding on necropsy is the presence of petechiae and linear hemorrhages on the tips of the proventricular glands or between the glands, along with button-like ulcers in the cecal tonsils.
- Infectious Bursal Disease (IBD): Characterized primarily by an enlarged, edematous, or hemorrhagic bursa of Fabricius, and hemorrhages in the thigh and breast muscles.
- Avian Spirochetosis: Characterized by marked splenomegaly (mottled spleen) and hepatomegaly, with fewer primary proventricular lesions.
- Aflatoxicosis: Characterized by hepatic lipidosis, icterus, cirrhosis, and immunosuppression, rather than acute hemorrhages in the proventriculus.
Step 3: Final Answer:
Therefore, linear hemorrhages between the proventricular glands are highly diagnostic of Newcastle disease.

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Anticholinergic drugs are not commonly used as antisialogogue in ruminants.
Reason (R): Administration of anticholinergic agents make the salivary secretions of ruminants thick and viscid, and thus predisposes them to airway obstruction.
