Manipulating rumen fermentation to improve performance

The process of rumen fermentation can easily be manipulated to improve animal performance and/or to better suit a given type of production. Here we review strategies to achieve these targets under different feeding and management conditions. Diet composition With the increased ratio of roughages-to-concentrates in the diet, the ratio of acetic acid-to-propionic acid in the rumen will increase, and the contrary will happen when the roughages-to-concentrates ratio decreases. The changes in the
