2020年12月23日 · Transmissible viral proventriculitis (TVP) of chickens is manifested in decreased body weight gains, poor feed conversion and weight diversity. Although TVP etiology has not been defined, a Birnaviridae family member, named chicken proventricular necrosis virus (CPNV) is considered as a potential factor of a disease.

Transmissible viral proventriculitis (TVP) is an infectious disease reported in the production of all types of chickens and has significant impact on the poultry industry. The typical pathological lesions observed in the course of TVP affect the proventriculus and are described as proventricular enlargement, thickening of its walls and spotty ...

Proventriculitis is a diseased condition characterized by enlargement of the proventriculus and weakness of the gastric isthmus. The disease is associated with retarded growth and low feed conversion.

2007年5月2日 · Proventriculitis was identified by a combination of proventriculus score (based upon size, tone, gastric isthmus dilation, whitish plaques and mottling on the outer surface, flattened papillae, and thickening of the mucosal surface) and increased proventriculus weight.

Proventriculitis in broilers causes carcass condemnation when swollen proventriculi tear during evisceration. The cause of this proventriculitis is unknown, but several infectious agents have been associated with it.

We investigated the occurrence and pathologic findings of transmissible viral proventriculitis (TVP) associated with the chicken proventricular necrosis virus (CPNV) in commercial broiler...

Infectious and non-infectious causes of proventriculitis, with major emphasis on the infectious or transmissible causes, are reviewed. This article reviews transmissible proventriculitis in poultry from 1971 to 2006. The disease is important in commercial broilers worldwide, resulting in …

2019年10月21日 · Transmissible viral proventriculitis (TVP) typically affects broiler chickens and is characterized by specific histological lesions, which include oxynticopeptic cell necrosis, lymphocytic inflammation and ductal epithelial cell hyperplasia of the submucosal glands (Hafner & …

2016年12月1日 · Increasing evidence suggests that a new birnavirus, named chicken proventricular necrosis virus (CPNV), is the aetiological agent of transmissible viral proventriculitis (TVP). The present work aimed to explore the possible presence of …

We investigated the occurrence and pathologic findings of transmissible viral proventriculitis (TVP) associated with the chicken proventricular necrosis virus (CPNV) in commercial broiler chickens in southeastern Brazil.
