Effect of potassium level on in vitro magnesium transport across rumen and omasum epithelium of cattle
… slaughtered at different times and rumen and omasum tissues were removed: The epithelium was separated from the muscle layer and mounted in parabiotic chambers. The tissues were incubated for 2 h in buffer at 39 C and aerated continuously in 95% O₂ 5% CO₂ . The buffers were similar to those …

An investigation of the distribution of gastrin-like activity, and its nature, in the gastrointestinal tract of the sheep
… has been located in the ovine rumen, reticulum, omasum, abomasal body, antrum, duodenum and caecum. The antrum showed the highest concentration of gastrin-like activity, but substantial concentrations were found in the rumen, reticulum, omasum and caecum and proximal duodenum declining …

Lysine and Glycyl-L-Sarcosine Absorption Across Ovine Forestomach Epithelium In Vitro
… absorption of amino acids and peptides by the omasum, and also suggest the mechanism involves mediated as well as possibly paracellular transport.

Tissue Distribution of a Peptide Transporter mRNA in Sheep, Dairy Cows, Pigs, and Chickens
… hybridization was observed with mRNA from the omasum, rumen, duodenum, jejunum, and ileum. The estimated size of mRNA was 2.8 kb. No hybridization was observed with mRNA from the abomasum, cecum, colon, liver, kidney, and semitendinosus and longissimus muscles of either species or the mammary …

Molecular Cloning, In Vitro Expression, and Functional Characterization of an Ovine Gastrointestinal Peptide Transporter (oPepT1)
… in the small intestine, at lower levels in the omasum, and at much lower levels in the rumen, but is not expressed in liver and kidney. The presence of the peptide transporter in the forestomach at such levels could provide amino acid nitrogen for the ruminant in a nutritionally significant …

Ontogenesis of Peptide Transport and Morphological Changes in the Ovine Gastrointestinal Tract
… were taken from the dorsal rumen, ventral rumen, omasum, duodenum, jejunum, and ileum. Villi were about 7% shorter (P < 0.09) in lambs receiving creep feed. Papillary height and width increased linearly (P < 0.001 and P < 0.0001, respectively) with age. Total and keratinized epithelial cells in …

Poly(A)+ RNA From Sheep Omasal Epithelium Induces Expression of a peptide Transport Protein(S) in Xenopus laevis Oocytes
In order to verify the research from this laboratory that sheep omasal epithelium contains mRNA encoding for a peptide transporter (s) and to determine di- to octapeptide transport capability, poly(A)+ RNA isolated from sheep omasal epithelium was injected into Xenopus laevis oocytes. Poly(A)+ RNA …

Observations on the Ruminal Protein Degradation Products and the Absorption of Ruminally Derived Free and Peptide-Bound Amino Acids via Ovine Forestomach Epithelia in Vitro
Production of ammonia N, a-amino N, and peptide N was investigated following in vitro ruminal incubation of solvent soybean meal (SBM), dehydrated alfalfa, corn gluten feed, fish meal, distillers dried grains with solubles (DDG), cotton seed meal, brewers fried grains, meat and bone meal, blood …
