Interpretive Summary:

Technical Abstract: Optimal rumen function is pivotal to health, production, and profit in dairy systems. Achieving that function requires an understanding of feeds and systems of nutritional evaluation. A key influence on optimal rumen function includes dry matter intake. The function of feeds in the rumen depends on other factors including chemical composition, rate of passage, degradation rate of the feed, availability of other substrates and co-factors, and individual animal variation. We discuss carbohydrate, protein, and fat metabolism in the rumen and provide practical means of evaluation of rations in the field. Conditions whereby rumen function is suboptimal (i.e., acidosis and bloat) are discussed, and methods for control are examined.
