FUNCTIONAL ADAPTATION OF THE RUMINAL EPITHELIUM
Short chain fatty acids (SCFA) synthesized in the rumen from carbohydrate fermentation are an essential energy source for ruminants. Current literature supports that SCFA are absorbed across the rumen epithelium via passive diffusion or protein-mediated transport, however, the rate and degree to …

Characterizing Thiamine Status and Mechanisms of Thiamine Supplementation on Subacute Ruminal Acidosis Attenuation in Dairy Cows
… 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 more and more attentions have been paid to prevent the occurrence of SARA in …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… diet, but these products may negatively impact rumen bacteria at high inclusion levels. Five ruminally-fistulated steers were used in a 5 × 5 Latin square design to determine the effects of increasing dietary fat and sulfur from (CDS) on the ruminal microbiome. Alpha-diversity and species …

Improving the Understanding of Factors Driving Rumen Fermentation
… products. Volatile fatty acids (VFA) produced by rumen microbial fermentation of feed substrates represent around 70% of the ruminant animal's metabolic energy supply. Rumen fermentation profiles may directly impact productivity because the types of VFA produced are utilized at differing …

Determining the added value of coproducts based adaptation diets and the heritability of variation in feed intake in Red Angus cattle
… of steps. This strategy allows time for the rumen epithelium and microbiome to adjust to high grain diets. Although grains are typically fed as the main energy source in a diet, grain coproducts also contain a great amount of easily digested fiber, which can decrease the risk for metabolic …

Effects of ruminal nutrient degradability on volatile fatty acid dynamics, ruminal epithelial gene expression, and post-absorptive system
… VFA concentrations, fluid flux and pool sizes, rumen epithelial metabolic and absorptive genes, and post-absorptive muscle and blood responses. Six ruminally cannulated Holstein heifers (BW=330 ± 11.3 kg) were used in a partially replicated Latin Square experiment with four treatments consisting …

Ruminal Degradation of Polyhydroxyalkanoate and Poly(butylene succinate-co-adipate)
… contain plastic foreign materials in their rumen. These materials are indigestible and accumulate for the lifetime of the animal. As these materials accumulate, they may reduce feed efficiency and production by erosion and ulceration of rumen epithelium, stunting of papillae, blockage of the …
