The rumen is lined on the luminal side by a stratified squamous epithelium that is responsible for not only absorption, but also transport, extensive short-chain fatty acid (SCFA) metabolism and protection. Butyrate has been demonstrated to initiate the differentiation of the tissue following introduction of solid feed to the weaning neonate as well as affecting the metabolism of other nutrient...

Numerous studies have been made of the quantitative aspects of the production of volatile fatty acids (VFA) in the rumen, and have been reviewed by Rook (1964), Warner (1964) and Annison (1965). Interest in rumen VFA production has recently been intensified because of the findings correlating body-weight increases with the concentration of rumen VFA in lambs on various pastures (Johns, Ulyatt &...

Using radioactive microspheres, mucosal and muscular capillary blood flow have been measured in the rumen, reticulum, and omasum of conscious sheep. Total forestomach capillary blood flow (7.7 ml min(-1) kg body wt(-1)) was about 7% of cardiac output; 95% of the flow was in the mucosa and only 5% in muscle layers. Blood flow in the rumen was 6 times higher than in the reticulum and 4.4 times hi...

in tannins and gaining optimal adjustment to tannin-rich diet requires time; thus, skilfully, goats prefer to safeguard their advantage in utilizing food that is available to them at all seasons. There is a positive interaction between the enhanced recycling rate of urea and a superior digestion of such food in goats adapted to harsh environment. The rumen plays an important role in the develop...

A comprehensive understanding of ruminal development and metabolism has not yet been achieved. The study of rumen epithelial metabolism during development can facilitate the development of feeding strategies for developing pre-ruminant animals and mature animals. Understanding the effect of the physical form and nutrient composition of the diet on the ruminal epithelium will lead to changes in ...

The use of agriculture by-products is highly demanded for livestock nutrition. However, the employment certain non-degradable materials could potentially induce concretions and lesions in ruminants’ forestomach. Thus, aim this study was to determine morphological showed rumen containing indigestible foreign objects, named bodies, small ruminants. Twenty-two animals (12 goats 10 ewes) presenting...
