Microbial activity in the omasum.
In a ruminant the omasum forms a relatively small ovoid chamber connecting the reticulum to the abomasum. The two orifices are fairly close together and connected by a channel in the omasal wall. The internal structure has been likened to a loosely-closed book with sheets of tissue forming the leaves and the spine opposite to the channel. ‘The omasal leaves are of various sizes; all leaves atta...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولCa-sensitive Na transport in sheep omasum.
Na transport across a preparation of sheep omasum was studied. All tissues exhibited a serosa-positive short-circuit current ( I sc), with a range of 1-4 μeq ⋅ h-1 ⋅ cm-2. A Michaelis-Menten-type kinetic was found between the Na concentration and the I sc(Michaelis-Menten constant for transport of Na = 6.7 mM; maximal transport capacity of Na = 4.16 μeq ⋅ h-1 ⋅ cm-2). Mucosal amiloride (1 mM), ...
متن کاملUltrasonography of the omasum in 30 Saanen goats
This report describes the findings of ultrasonographic examination of the abomasum in 30 goats. A 5.0 MHz linear transducer was used to scan the left and right paramedian regions, the linea alba and the right abdominal wall of standing goats. The abomasum appeared as a heterogeneous, moderately echogenic structure with echogenic stippling. The abomasum could be seen from the linea alba in all t...
متن کاملMicrobial Activity in Bovine Rumen
bengal, asparagus agar (Allen, 1951), asparagus agar plus 1:80,000 crystal violet, and asparagus agar plus 1:15,000 rose bengal. The addition of dyes decreased the number of contaminants but also appeared to inhibit the development of the rhizobia. All plates were examined daily for 2 weeks. Smears of colonies which resembled rhizobia were examined. Pure cultures were obtained by the use of bot...
