Correlations between states of amino acids and hematology or plasma biochemistry in calves within 24 hours after birth

The present study examined correlations between state of free amino acids and hematological or plasma biochemistry, using blood samples acquired from Japaneseblack calves within 24 hours after birth.All of free amino acids demonstrated negative correlations with red blood cell counts, hemoglobins and hematocrits.The most significant positive correlation was recorded between γ-glutamyl transpeptidase and glutamic acid, with a linear regression of y=0.025 x+39.99,where x corresponds to γ-glutamyl transpeptidase and y corresponds to glutamic acid (r=0.88,p<0.001).This suggests glutamic acid concentration may relate to the degree of colostrum intake in Japanese-black newborn calves.
