| Abstract | ||
| The morphological characters of ovaries were studied in fifty one slaughtered Egyptian pregnant buffaloes including the weight and diameter of corpora lutea, and the number and sim of follicles. Progesterone and estradiol- 17 β concentrations were estimated in both peripheral plasma and feces using Enzymimmunoassay. The results revealed a decrease in number of all sized follicles as pregnancy advanced, Plasma and fecal progesterone concentrations increased and plasma estradiol-17 β levels decreased with the progress in pregnancy. Positive Correlation Coefficients existed between the ovarian weight and weight of corpora lutea in one side, and between the number of follicles and estradiol-17 β levels on the other side. The Correlation Coefficients between the weight of corpora lutea and estradiol-17β levels were negative Seasonal differences in ovarian activity occurred in pregnant buffaloes coincided with the profound effect of season on the progestin and estradiol-17 β concentrations in the peripheral plasma. | ||
