Proventriculus - Wikipedia
The proventriculus is a standard part of avian anatomy, and is a rod shaped organ, located between the esophagus and the gizzard of most birds. [2] It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [3] The primary function of the proventriculus is to secrete ...

The proventriculus is the glandular compartment, which is functionally equivalent to the mammalian stomach. The proventriculus is a fusiform organ that varies in size and shape among avian species, being relatively small in granivorous species and relatively large in carnivorous and piscivorous species (Figs. 1 and 2) [2].In all birds except carnivore and piscivore species, the mucosal surface ...

2020年12月23日 · These proventriculi were stored frozen (−20 °C) prior to infection. After homogenization of defrosted samples, proventriculi were processed through three freeze–thaw cycles. After centrifugation (2000× g, 15 min), the supernatant was stored and used for the infection. Broiler chickens from the TVP-infected group were inoculated with 5 mL ...

2009年7月9日 · Histomorphology of the proventriculi of nectarivorous, granivorous and omnivorous passerines was studied. The proventriculus consisted of mucosal, submucosal, muscularis and serosal layers. Proventricular wall was thickest in omnivore, thinnest in granivore and intermediate in nectarivore. The openings of mucosal glands had a single spiral-like ...
