Lysine and Glycyl-L-Sarcosine Absorption Across Ovine Forestomach Epithelium In Vitro
Lysine absorption by ruminal and omasal epithelia was studied using parabiotic chambers that were sampled for 60-min. Lysine appearance in serosal buffers and the accumulation of lysine in tissues increased linearly (P < .001) with time. Lysine appearance in serosal buffers of ruminal tissue …

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
… Collectively, these results indicate that the forestomach epithelia of sheep possess the potential to absorb ruminally derived peptides (relatively large amounts) and free amino acids (relatively small amounts). Also, the ruminal microbial degradation of dietary proteins may influence the …

Absorption of carnosine and methionylglycine by sheep ruminal and omasal epithelia
… was demonstrated. Dipeptide translocation across forestomach epithelial tissues, which has not been reported previously, may be an important route for supplying dietary amino acids to the ruminant.

Demonstration of peptide and free amino acid absorption by sheep forestomach epithelium using parabiotic chambers and identification of H⁺/peptide and free amino acid transport proteins in sheep omasal epithelium and b<sup>o,+</sup> amino acid transport proteins in pig jejunal epithelium by expression of mRNA in Xenopus laevis oocytes
The absorption of methionine and methionylglycine (Met-Gly) across sheep (average BW = 38 kg) ruminal and omasal epithelia was studied using parabiotic chambers. Ruminal tissue demonstrated a greater ability to accumulate both substrates. Omasal tissue demonstrated a greater ability to translocate …

Molecular Cloning, In Vitro Expression, and Functional Characterization of an Ovine Gastrointestinal Peptide Transporter (oPepT1)
… The presence of the peptide transporter in the forestomach at such levels could provide amino acid nitrogen for the ruminant in a nutritionally significant manner. Transport function of oPepT1 was assessed by expressing oPepT1 in Xenopus oocytes using a two-electrode voltage-clamp technique. …

An investigation of the distribution of gastrin-like activity, and its nature, in the gastrointestinal tract of the sheep
… there to be gastrin-like activity present in the forestomach, mainstomach, pyloric stomach, duodenal ampulla and intestine of this mammal. The distribution of gastrin-like activity reported in the present work has been compared to previous reports concerning the distribution of gastrin activity in …

Functional Heterogeneity and Metabolic Adaptation of Fibroblasts In Cancer
… growth, resulting in squamous carcinoma of the forestomach. In our studies, we uncovered a complex feed forward loop, in which the loss of Tgfb receptor 2 in FSP1+ fibroblasts leads to a Smad4-dependent up-regulation of HGF production to induce increased proliferation in neighboring epithelial …

Environmental, Biochemical, and Dietary Factors that Influence Rumen Development in Dairy Calves
… with increased starter intake. Total empty forestomach (P = 0.014) and reticulorumen weights (P = 0.012) were greater in LPSB compared to BUTY. Overall, LPS and sodium butyrate appeared to have synergistically affected some, but not all rumen measurements without affecting calf growth, …

Duodenal and ileal digestibility of dietary nutrients and endogenous protein losses in pre- and post-weaning young dairy calves
… the test ingredient were greater for ESBM. The forestomach and intestinal digestion parameters suggest that an optimal balance of CP and the inclusion of previously hydrolyzed proteins improved the efficiency of microbial digestion and increased AA absorption despite a lower proportion of …
