A adult desi fowl carcasses were presented for post mortem examination with the history of weak and sudden death. External examination revealed ruffled feathers, occluded nostrils and closed beak. The internal examination revealed numerous light white tiny nodules about 1-2 mm in size on the oesophageal mucosa, fibrin layer adhered to the pericardium, congested intestinal mucosa, mild petechiae on the cecal tonsils and congested meningeal blood vessels. Histopathological examination revealed squamous metaplasia of the submucosal oesophageal glands, multifocal necrosis in the liver and necrotic enteritis. Based on the clinical signs, gross and histopathological examination, the condition was diagnosed as nutritional roup and it could be due

Birds maintained with vitamin A deficient diet exhibit clinical signs like cessation of growth, drowsiness, weakness, staggering gait, emaciation, ruffling of feathers, lack of yellow pigment in shanks and beaks, pale comb and wattle, lachrymation, presence of cheesy-like material under the eyelids and xerophthalmia. The present paper reports on the occurrence of nutritional roup in a desi fowl reared under semi intensive system of poultry farming.
Materials and Methods A desi fowl carcasses of one year old with the history of weak and sudden death from a private farm were submitted to the Department of Veterinary Pathology, Veterinary College and Research Institute, Tirunelveli for post mortem examination. The birds were subjected to the detailed postmortem examination and the appropriate tissue samples were collected in 10 per cent formalin. The formalin fixed tissue samples were processed, paraffin embedded sections cut into 4 m thickness and stained with Hematoxylin and Eosin (H&E) for histopathological examination as per the standard procedure described by Bancroft and gamble …show more content…
The farmers were maintained the birds by feeding with own feed preparation and the balanced ration were not followed. Due to unavailability of large land holding, many farmers prefer intensive system of poultry farming even for desi fowls. This is also another reason for low plan of nutrition and Vitamin A deficiency. In the present study, the nutritional roup was recorded in above one year old birds were indicated that the problem was chronic in nature with the birds were kept in low vitamin A diet. Based on the clinical signs, gross and histopathological examination, the death of the bird is due to nutritional roup.
Summary Nutritional roup was recorded in above one year old desi fowl and presented
