Nitrogen is a component of essential nutrients critical for the productivity of ruminants. If
excreted in excess, N is also an important environmental pollutant contributing to acid …

Physical and chemical processing of feed ingredients and feeding management strategies
are major instruments of manipulating amount and site of starch digestion in the …

Movements of N across the gut can be more than double N intake and thus have major
effects on N metabolism of the ruminant. These movements may be associated with net …

Nineteen lactation trials (43 grain processing comparisons) are summarized, in addition to
digestibility and postabsorptive metabolism studies. The net energy for lactation (NEL) of …

The maintenance of an optimum nutrient balance in ruminant animals for growth, pregnancy
and lactation is of key economic importance, requiring a wide range of adaptive responses …

The transport of nitrogen across the rumen epithelium is characterized by absorption of
ammonia from the rumen and by an influx of urea into the rumen. The transport rates of both …

The size of the liver of terrestrial mammals obeys the allometric scaling law over a weight
range of> 3∗ 10 6. Since scaling reflects adaptive changes in size or scale among otherwise …

Summary ― Major functions of portal-drained viscera (PDV) and liver of cattle include
absorption of digestion products and modification of the body's supply of intermediary …

The predictability of diet effects on milk composition is limited by the lack of understanding of
the metabolic transformations that absorbed nutrients undergo within the portal-drained …

Postruminal intestinal barrier dysfunction caused by excessive hindgut fermentation may be
a source of peripheral inflammation in dairy cattle. Therefore, the study objectives were to …
