Developmental changes in free amino acid and low molecular weight peptide of blood from growing cockerel.

Abstract

pattern similarity between 1 or 2 weeks and 30 weeks of age of cockerel showed a relatively low ratio, 0.846 or 0.828 respectively. On the other hand, free amino acid composition in plasma from cockerel did not change in relation to aging, and no significant difference was found among free amino acid compositions in plasma from cockerel, adult male Japanese quail and domestic drake.
