[Ammonia metabolism in tissue of newborn animals in health and in digestive disorders].

Ammonium nitrogen was studied for its metabolism in the tissues of ruminants in transition from pre- to postnatal development in norm and with disorders in gastroenteric digestion. It is established that the intensity of ammonium genesis and glycolysis processes as well as a cycle of tricarbonic acids change in newborn calves as compared to adult animals. The ammonium toxicosis development in sick animals, which is confirmed by an increase of the ammonia level and intensification of the reactions of ammonium- and ureogenesis in tissues of the gastroenteric tract, liver and kidneys.
