Abstract
The seeming and the actual absorption of amino acids of three pigs with a body mass of 50 kg was determined by inserting re-entrant cannulas at the upper small intestine and its end. The test ration contained dry curds labelled with 15N. The content of N and of amino acids as well as the 15N-excess in the amino acids were determined in the food and the chyme. This served the ascertainment of the actual absorption of amino acids in the small intestines.
