Abstract: Ovarian changes determined by daily transrectal ultrasonic scanning, and its correlation with serum progesterone (P4) and estradiol (E2) concentrations were studied in seven cyclic Saanen goats. Estrous cycles were synchronized with 2 injections of a PGF2? analogue 9 d apart. All follicles ?2 mm in diameter and CL were measured each day. One goat showed a longer interestrous interval, associated with development of a cystic-luteinized structure. The mean interovulatory interval for the other 6 goats was 20.8±0.4 d. The incidence of goats with 4, 3, and 2 follicular waves was 3, 1 and 2 respectively; follicular waves emerged on Days 0.5±0.6, 7.2±0 7, 10.7±0.5 and 13.7±0.8 for Wave 1, 2, 3 and the Ovulatory wave, respectively. The largest follicle of Wave 2 was smaller (4.9±0.1 mm) than the largest follicles of Wave 3 (6.2±0.1 mm; P?0.01) and of the Ovulatory wave (7.0±0.5 mm; P?0 01), and tended to be smaller than the largest follicle of Wave 1 (6.3±0.6 mm; P?0 09). Interval between emergence of Wave 1 and Wave 2 was longer than interval between emergence of Wave 2 and Wave 3 (7.3±0.9 d vs 4.0±0.4 d; P?0.01), and between Wave 3 and the Ovulatory wave (3.8±1.1 d; P?0.05). Two days before ovulation, the diameter of the ovulatory follicle was larger (P?0.01) than the first subordinate follicle Serum E2 concentrations increased from the day of ovulation (2 7±0 3 pg/mL) to Day 2 (7.6±0.9 pg/mL; P?0.01), associated with the early-mid growing phase of the largest follicle of Wave 1, and then decreased to basal levels on Day 5 (P?0.01) and peaked again (16 5±2 4 pg/mL) 2 d before ovulation. The CL were detected ultrasonically on Day 3 post ovulation and attained a mean maximum diameter of 13.5±0.8 mm between Days 8 and 14 The following characteristics were observed: 1) ovarian follicular development in goats is wave-like; 2) increased P4 concentrations may be promoting follicular wave turnover; 3) it is suggested that the presence of follicular dominance and the production of E2 are different among waves. While in Wave 1 and in the Ovulatory wave, follicular dominance is present and production of E2 is consistent, no changes in serum E2 concentrations were found in other stages of the interovulatory interval. In the intervening waves, no indicators of follicular dominance could be firmly documented MenosAbstract: Ovarian changes determined by daily transrectal ultrasonic scanning, and its correlation with serum progesterone (P4) and estradiol (E2) concentrations were studied in seven cyclic Saanen goats.
