FUNCTIONAL ADAPTATION OF THE RUMINAL EPITHELIUM
… supports that SCFA are absorbed across the rumen epithelium via passive diffusion or protein-mediated transport, however, the rate and degree to which these pathways adapt to a change in diet fermentability is unknown. Furthermore, Na+ flux is partially determined by SCFA absorption, and thus is a …

EFFECT OF LIPID SUPPLEMENTATION ON RUMINAL EPITHELIAL MEMBRANE FATTY ACID COMPOSITION AND SHORT-CHAIN FATTY ACID ABSORPTION
… and lipid type on the FA composition of the ruminal epithelium and absorption of SCFA. Twenty-one Holstein steers (194.1 ± 26.77 kg) were randomly assigned to the control (CON; 2.2% ether extract) or 1 of 2 lipid supplementation treatments (5% ether extract) utilizing saturated (SAT) or …

Influence of feed efficiency ranking and maternal nutrition on gut microbiome, metabolome, and transcriptome in beef and dairy cattle
… experiment was to determine differences in major ruminal bacteria and ruminal epithelium gene expression between most-efficient (M-eff) and least-efficient (L-eff) finishing beef cattle. Results indicated that superior feed efficiency in beef cattle is associated with differences in bacterial …

Absorption of carnosine and methionylglycine by sheep ruminal and omasal epithelia
… marker) absorption and transfer across ruminal and omasal epithelia collected from four (carnosine) and seven (methionylglycine) sheep were studied using parabiotic chambers that were repeatedly sampled over a 240-min incubation. The quantity of dipeptide absorbed or transferred was …

Tissue Distribution of a Peptide Transporter mRNA in Sheep, Dairy Cows, Pigs, and Chickens
To study the mRNA found in sheep omasal epithelium encoding for a peptide transport protein(s), a 446-bp cDNA fragment was cloned from sheep omasal epithelium RNA. The predicted amino acid sequence of this fragment was 85.8, 90.5, and 90.5 percent identical to rabbit, human, and rat PepT1, …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… nutrients. Several of these factors include the ruminal microbiome composition and epithelial tissue function, and nutrient provision in utero. The objective of this dissertation was to evaluate the effects of nutrition on these physiological effects to determine their potential to influence …

EFFECTS OF DIETARY COMPOSITION AND FEEDING MANAGEMENT REGIMEN ON FEEDLOT CATTLE PERFORMANCE
… ear tag (AllFlex), and an indwelling ruminal pH bolus (SmaxTech). Data from the technologies were collected from d 0 to d 150. At harvest, a tissue sample from the subset was collected from the ventral sac of the rumen, adjacent to the cranial pillar, and from the colon. The tissues …

Characterizing Thiamine Status and Mechanisms of Thiamine Supplementation on Subacute Ruminal Acidosis Attenuation in Dairy Cows
… high grain diets increases the risk of subacute ruminal acidosis (SARA), which is characterized by prolonged decrease in rumen pH and high levels of lipopolysaccharide (LPS). SARA challenge has been confirmed to severely impair animal health, production performance and farm profitability, and …
