| Abstract | The present study aimed at instigating the buffalo ovarian and uterine response to ovsynch protocol when initiated 21 days postpartum (pp). Animals were arranged into a treated (n = 3) and a control (n = 3) group. The treated group was given the first dose of GnRH on day 0 (day 21 pp) followed by PGF2 alpha on day 7 and the second dose of GnRH on day 9. All animals were allowed a daily ultrasound examination from day 1 to day 9 and then every 12 h until detection of ovulation. The ovarian response of the treated group clearly showed the organized events of follicular growth ended by ovulation in one animal (33.3 percent) of the treated group, the changes in the small, medium, large and total follicle population and area did not differ significantly between the two groups, luteinization of the dominant follicle following the first GnRH injection in two animals (66.6 percent) indicated the reliability of the ovsynch strategy to improve the ovarian function, the uterine response was clearly evidenced by increasing the uterine wall homogeneity, decreasing the uterine lumen (less than 0.3 cm) and clearing contents by day 7-8 in the treated group. In conclusion, the ovsynch protocol has a beneficial effect on the ovarian function and uterine involution when applied 21 days pp in buffaloes. |
