title: [Alanine and aspartate transaminase and acid and alkaline phosphatase activities in the blood serum in relation to the protein and energy levels in the pigs' feeds].
abstract: The activity of alanine and asparagine transaminase and of acid and basic phosphatase was studied in blood serum of 72 porkers of the Polish large-white breed, fed with PT-2 feeds of various protein and energy levels. It was found that the activity of both transaminases in blood serum depended on the protein-energy level of the diet. The activity of transaminases was not found to increase at the protein content compatible with the standard and at increased energy value of the feeds, whereas the same protein level and decreased energy amount caused a decrease in the activity of alanine and asparagine transaminase. At a decreased protein content in the diet the activity of transaminases in plasma was lower than in the porkers on a diet containing protein according to the standard. An increased amount of energy with a decreased protein content in the diet did not affect the activity of asparagine transaminase but slightly stimulated alanine transaminase, whereas a decrease in the amount both of energy and protein in the diet caused an increase in the activity of both transaminases. Acid and basic phosphatase were not adequate indices of changes in the organism of the porkers in relation to the protein-energy level of their diet.
