[Selected factors of metabolism in ruminants fed with increasing doses of urea in the food. I. Liver function in cows in the light of the activity of selected enzymes and the levels of indicators of protein metabolism].

The authors studied the influence of urea added to diet in an amount of 150 grams daily per 1 cow on the function of the liver by means of: determination of the activity of the following enzymes: arginase, ornithin-carbamyl-transferase, leucyloaminopeptidase, gamma-glutamyl-transferase, phosphatase alkaline, determination of the level of total protein, albumins and globulins, urea, sodium and potassium in the serum of dairy cows. No significant changes were found in the activity and in the content of the above mentioned blood constituents. The dose of 150 grams of urea added to diet did not show any disturbances in protein metabolism in the liver and in the health of the cows.
