Conteúdo: 	Abstract: Concentrations of amino acids, urea, glucose, fructose and corticosteroids were measured in maternal and fetal plasma from nine Scottish Blackface ewes during the last 35 days of pregnancy. During this period maternal plasma levels of most amino acids did not change significantly. In fetal plasma the concentrations of most amino acids decreased or remained relatively constant until about 20 days before birth (day -20) and then increased as term approached. Glucose levels in plasma from both sources did not change, but urea concentrations rose to maximum values about day -20. Except for valine and isoleucine, the concentrations of amino acids in fetal plasma varied independently of levels in maternal plasma up to day -20, but thereafter 10 amino acids, including seven essential amino acids, showed a significant positive correlation with maternal values. Possible causes of the observed variations in fetal plasma composition are discussed.
