ABSTRACT
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) 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.
ABSTRACT
Objective: To enhance effectiveness of reproduction management in Arabian mares, factors influencing the time of foaling were investigated in this study. Methods: Data were collected at the National Haras of Tiaret in Algeria from 2003 to 2010. The foaling time of 255 Arabian pure bred mares, aged from 3 to 20 years were used for this study. Results:A total of 78.07%of foaling happens between 7 pm and 6 am. Conclusions:The influence of the month of foaling and the sex of the foal, on the time of foaling was statically significant.
