Observation on Free Amino Acid of Sheep Blood Plasma

Abstract

The concentration of amino acids in the plasma from female sheep was determined. The plasma amino acid pattern was very similar to that of cow which was investigated in authors' laboratory. The concentration of glycine was considerably higher than that of alanine; this is the reverse of the pattern in man and cat. When the animal was fed on the severe low DCP diet, the concentration of glycine in the plasma was higher than that in the normal feeding. The concentration of amino acids among the portal, jugular vein, and carotid artery was compared.
