Ruminants take in considerable amounts of nitrogen in the form of ammonia, which is absorbed and converted to urea in the liver. Rising nitrogen intake causes an increase in both ammonia and urea production. This is associated with an increase in the liver clearance of amino acids. The cause of this association is undetermined, but the utilization of aspartate or glutamate in ureagenesis and its connection to other liver functions are implicated. Amino acids are also potential sources of carbon for glucose synthesis, therefore, gluconeogenesis may also contribute to the amino acid clearance rate of the liver.
