Gene expression profiles in ruminal tissue from cows fed high or low concentrate diets

ABSTRACT: Cattle are often fed high concentrate diets to increase energy intake and improve overall animal performance. Such diets also cause changes in fermentation patterns and epithelial function. However, the molecular mechanisms involved in regulating epithelial function for cattle fed high concentrate diets have not been elucidated. In this study, we aimed to gain a broad overview of the involved molecular mechanisms by detecting differentially expressed genes (DEG) in rumen tissue from dairy cows fed a low concentrate (LC; 8%) compared to a high concentrate (HC; 64%) diet using a bovine-specific microarray platform containing 16,846 unique gene loci and 5,943 ESTs from the bovine genome. Feeding the HC diet increased the total volatile fatty acid concentration and markedly reduced ruminal
