Serum amino acid levels in young, adult, pregnant (day 12 and 21) and lactating (day 20) rats have been described and compared with plasma concentrations. Serum values systematically overestimate the amino acid plasma content. Changes reported for plasma amino acid levels in midpregnant and lactating rats are well reflected in the serum values. This is not the case for adult and late pregnant rats.
