“…The concentrations of phosphoserine, taurine and ornithine had significant correlation coefficients for all of the fluid compart¬ ments tested. The total FAA in bovine fetal serum reported here is greater than the FAA reported for the adult cow by Verbeke et al (1972) and by Love & Wiygul (1969), who used the same methodology. Threonine is 3 and alanine is 6 more concentrated in the fetus than in the adult.…”

Summary. Thirty ninhydrin-positive compounds were determined in the sera, amniotic fluid, stomach content and allantoic fluid from 29 bovine fetuses of various gestational ages. Fetal serum was found to contain about 3-fold higher concentrations of free amino acids (FAA) than maternal serum, and allantoic fluid contained about 3-fold higher concentration of FAA than fetal serum. Decreasing concentrations of FAA were found in serum as a function of the crown-rump length for the amino acids taurine, aspartic acid, threonine, serine, ornithine and lysine. Decreasing concentrations of FAA in allantoic fluid were found for threonine, alanine and ornithine, whereas increasing concentrations were found for phosphoserine and methionine as a function of the crown-rump length. Correlations were found between the concentrations of most amino acids in amniotic fluid and stomach content, but fewer correlations were found between the other fluid compartments. The transport of amino acids between compartments is discussed.
