Current NRC recommendations for dairy cattle provide limited guidance to nutritionists for
meeting the fiber and carbohydrate needs of lactating cows. The NRC provides only …

Highly fermentable diets are rapidly converted to organic acids [ie, short-chain fatty acids
(SCFA) and lactic acid] within the rumen. The resulting release of protons can constitute a …

Feeding diets high in grain and other highly fermentable carbohydrates to dairy cows
increases milk production, but also increases the risk of subacute ruminal acidosis (SARA) …

Volatile fatty acids (VFA) and lactic acid can build up in the rumen and reduce ruminal pH.
Low ruminal pH for prolonged periods each day can affect feed intake, microbial metabolism …

The existence and diversity of human cultures are made possible by our species-specific
cognitive capacities. But how? Do cultures emerge and diverge as a result of the …

The Cornell Net Carbohydrate and Protein System (CNCPS) is a mathematical model that
estimates cattle requirements and nutrient supply based on animal, environmental, and feed …

We examined the role of trans-octadecenoic acids in milk fat depression when low fiber diets
were fed. The study consisted of four experimental periods with a 2× 2 factorial arrangement …

Agriculture contributes significantly to the anthropogenic emissions of non-CO2 greenhouse
gases methane and nitrous oxide. In this paper, a review is presented of the agriculture …

The contribution of greenhouse gas (GHG) emissions from ruminant production systems
varies between countries and between regions within individual countries. The appropriate …

The main objective of this study was to develop practical models to assess and predict the
adequacy of dietary fiber in high-yielding dairy cows. We used quantitative methods to …
