Provedor de dados: 77
Autores: Wang,Jinbao; Li,Haiyan; Zhang,Lu; Zhang,Yuan; Yue,Mingxia; Shao,Baoping; Wang,Jianlin.
Six forestomachs of yaks (Bos grunniens) were studied with gross dissection and histological methods. It was found that the forestomach of yak consisted of the following three parts, rumen, reticulum and omasum, which were composed of the mucosa, submucosa, muscularis and serosa. In addition, the mucosal epithelium was covered with stratified squamous epithelium, with part of keratinized the shallow cells. Rumen, the mucosa of which formed ligulate papillae varying in size and shape, was no muscularis mucosa. Reticulum, consisted of a surface epithelium that invaginated to various extent into the lamina propria, formed various folds in shape, namely, grid-like small rooms. Furthermore, there are many secondary folds densely covered with keratinized...

Gross Anatomy of the Stomach of the Cervus Elaphus barbarus
Provedor de dados: 77
Autores: Jerbi,Hassen; Pérez,William.
The barbary stag is an intermediate feeder ruminant of the Cervidae family. The macroscopic anatomy of the stomach in one adult barbary stag was described. The stomach of the barbary stag was composed of the four classic compartments of the ruminants. The weight of the full stomach was 10.5 Kg. The ruminal papillae were distributed unevenly in the rumen. The maximum height of the cristae reticuli was 0.2 cm. The cellulae reticuli were mostly undivided. The curvatura omasi measured 15.0 cm and the omasum had 15 primary, 10 secondary, 10 tertiary and 17 cuaternaryLaminae omasi. The abomasum had about 12 plicae spirales abomasi.We concluded that the stomach morphology of the barbary stag had characteristics of other intermediate feeder ruminants.

Gross Anatomy of the Stomach of the Dorcas Gazelle (Gazella Dorcas, Linnaeus, 1758)
Provedor de dados: 77
Autores: Jerbi,Hassen; Bayoudh,Mohamed; Clauss,Marcus; Pérez,William.
The macroscopic anatomy of the stomach in four adult dorcas gazelle was described. Four adult, two male and two female dorcas gazelle (Gazella dorcas) of the Frigya Zoological Park, Enfidha, Tunisie, were used in this study. The ruminal papillae were distributed unequally in the rumen, and were larger and more abundant within the atrium and in the two saccus cecus. The papillae were absent in dorsal part of the dorsal sac. The ruminal pillars had no papillae. The cellulae reticuli were divided and contained secondary and tertiary crests. The curvatura omasi measured 12.1±0.1 cm. A comparison with literature data for sand gazelles (Gazella subgutturosa marica) emphasises that differences between closely related species that fill similar niches cannot be...

Gross anatomy of the stomach of the pampas deer, Ozotoceros bezoarticus (Artiodactyla: Cervidae)
Provedor de dados: 103
Autores: Perez,William; Ungerfeld,Rodolfo.
The macroscopic anatomy of the stomach of the adult pampas deer, Ozotoceros bezoarticus (Linnaeus, 1758), a cervid species considered to ingest high quantities of grass in its natural diet, was described. Fourteen deceased adult pampas deer of both sexes from a captive breeding station were used for this study. There were no differences in the absolute or relative size from the different compartments of the stomach in relation to gender. Compared to measurements in other ruminants, pampas deer appeared anatomically capable of feeding on a variety of diets as an 'intermediate feeder'.

Absorption and metabolism of volatile fatty acids by rumen and omasum
Provedor de dados: 64
Autores: Daniel,João Luiz Pratti; Resende Júnior,João Chrysostomo de.
Volatile fatty acids (VFA) absorption and metabolic capacity of rumen and omasum were compared, in vitro. Fragments of rumen wall and omasum laminae were taken from eight adult crossbred bovines. An isolated fragment of the mucosa was fitted in a tissue diffusion chamber. Valeric acid and CrEDTA were added to ruminal fluid and placed on the mucosal side and buffer solution was placed on the serosal side. Fractional absorption rates were measured by exponential VFA:Cr ratio decay over time. Metabolism rate was determined as the difference between VFA absorbed and VFA which appeared on the serosal side over time. Mitotic index was higher in omasum (0.52%) than in rumen epithelium (0.28%). VFA fractional absorption rate was higher in omasum (4.6%/h.cm²) than...
