Objective: To evaluate the energetic profile of fetal fluids and to make comparisons of the concentrations of the constituents present with those in the maternal plasma. Methods: A study was conducted in 102 gravid sheep uteri. The four stages of gestation as Stage I (0-60 days), Stage II (61-90 days), Stage III (91-120 days) and Stage IV (121-145 days) were identified based on the crown anus length of the embryo/fetus. The amniotic and allantoic fluids collected from the gravid uteri of each group were subjected to biochemical analysis of glucose, cholesterol and triglyceride. Results: The levels of glucose and triglyceride in maternal plasma were lower (P < 0.05) on late pregnancy as well as in amniotic and allantoic fluids. No significant variation (P > 0.05) of plasma cholesterol levels was detected between the sampling periods. Contrariwise, cholesterol concentrations of fetal fluids were higher in Stages III and IV of pregnancy when compared with the Stages I and II. Conclusions: The influence of pregnancy on the biochemical composition of fetal fluids was statistically significant.
