Abstract:

The study was designed to find correlation between antral follicle count (AFC), plasma levels of estradiol and progesterone with superovulatory response and embryo production in Sahiwal cows. Pluriparous Sahiwal cows (n=12) were administered estradiol-17β (2 mg, i.m.) along with intravaginal placement of progesterone implant (TRIU-B) at random day of the estrous cycle (day 0). On day 4, cows were administered Folltropin-V @ 100 or 200 mg of NIH FSH PI, divided in 8 tapering doses administered at 12 hourly intervals. PGF2α was given on day 6 and day 6.5; Implant TRIU-B was withdrawn with last FSH injection. Cows were fixed timed inseminated at 24 and 36 hours of last FSH dose. Results showed that the AFC at start of FSH administration (Day 4) had high positive and significant correlation with superovulatory response (r = 0.863, p = 0.0003). Mean plasma estradiol was non significantly higher on day of estrus (Day 8) compared to the day of start of FSH treatment (Day 4) and day of embryo collection (21.8±3.27, 26.4±3.32 and 21.6±2.99 pg/ml, respectively). The number of anovulatory follicles (>10 mm) present on the day of embryo collection had negative and significant correlation with number of transferable embryo (r = - 0.609; P = 0.0355). Plasma progesterone had a weak negative correlation with >10 mm follicles (r = -0.311, P>0.05) on day of estrus and a weak positive correlation with superovulatory response on the day of embryo collection (r = 0.332, P>0.05). In conclusion, the study indicated that antral follicle count on the day of ovarian stimulation could be used to predict superovulatory response and persistence of anovulatory follicles till the day of embryo collection had adverse effect on embryo quality in Sahiwal cows.
