Microbiology of the Rumen
The fundamental challenge of ruminant nutrition is still optimization of rumen function. Given that ruminant animals consume diets that are primarily made up of carbohydrates and protein, how the rumen converts this substrate into end-products is of critical importance. The major products of nutritional importance are volatile fatty acids and microbial protein. Many ruminant nutritionists agree that microbial and volatile fatty acid yield of individual feeds is not always additive when feeds are mixed. It is suspected that the interactions between microbial communities are fundamental to our understanding of how feedstuffs interact. A limitation has been our lack of knowledge of the microbial diversity of the rumen. It is well know that high producing dairy cows experience metabolic stress largely related to the high concentrated diets that are fed. When dairy cows experience stress related to high concentrate diets significant changes occur in the rumen, many of which lead to pathologies, and potentially reduce the quality of milk.
