The objectives of this study were to: (1) evaluate the feasibility of ultrasonic biomicroscopy (UBM) for imaging ovarian follicles in vivo in cows and heifers, (2) compare the transvaginal to the transrectal approach, (3) compare the number of follicles detected by UBM to conventional ultrasonography (US), and (4) identify cumulus-oocyte-complexes (COC) within follicles by UBM. Mature cows (n = 5) and peri-pubertal heifers (n = 5) were examined once using conventional B-mode US (Aloka 900) with a 7.5 MHz transrectal, and a 5 MHz transvaginal transducers. A second series of examinations was performed using UBM (Visualsonics Vevo 660) equipped with a 30 MHz transrectal and a 40 MHz transvaginal transducer. A three- to four-fold increase in the number of small follicles (<3 mm) was detected using the transvaginal approach with UBM compared to conventional US in both heifers (32.4 ± 4.24 compared to 7.2 ± 1.4; P < 0.0001) and cows (35.0 ± 13.8 compared to 10.7 ± 7.5; P = 0.0013). However, fewer follicles (all sizes combined) were detected using the transrectal approach with UBM compared to conventional US in both heifers (8.6 ± 5.6 compared to 17.6 ± 4.9; P = 0.02) and cows (5.3 ± 6.1 compared to 20.3 ± 7; P = 0.04). In heifers, COC-like structures were identified in 39 of 202 (19.3%) follicles examined. In conclusion, UBM using a transvaginal approach is feasible and may be used for in vivo assessment of early antral follicles as small as 0.4 mm, and COC within follicles. |
