This study was performed to investigate the FSH levels for superovulation procedure in Korean Native Cattle (Hanwoo).
The effectiveness of 200 mg and 400 mg of FSH to initiate superovulation was examined in Hanwoo. Donors, at random stages of the estrous cycle, received a CIDR. 7 days later, 200 mg FSH group was treated with 40, 30, 20, 10 mg FSH levels in declining doses twice daily by intramuscular injection for 4 days. Also, 400 mg FSH group was treated with 80, 60, 40, 20 mg FSH levels. On the 3rd day administration of FSH, 25 mg PGF2α was administered and CIDR was withdrawn. Donors were artificially inseminated twice at 12 hr intervals. The donor cattle received 250 μg GnRH at time of 1st insemination and embryos were recovered 8 days after the 1st insemination. As a results, average number of CL treated with FSH 200 mg was higher as 20.9±1.20 than 15.8±0.63 for donors treated with FSH 400 mg, respectively(p<0.05). Treated group of 200 mg FSH level increased (p<0.05) the number of embryos recovered per procedure compared to 400 mg FSH level (18.2±1.18 vs. 12.38±0.52, respectively). When treatment of 200 mg FSH was performed, average transferable embryos/ova increased (p<0.05) to 14.1±1.12 from 6.8±0.33 of treated of 400 mg FSH. Group of 200 mg FSH increased (p<0.05) to 8.3±0.76 from 2.0±0.26 in morula stage compare to 400 mg FSH group.
Mean of total early blastocyst and expanded blastocyst stage embryos was similar (p<0.05) between the 200 mg and 400 mg FSH levels group (4.7±1.19 vs. 2.9±0.18 and 1.2±0.40 vs. 1.9±0.17). These results suggest that 200 mg FSH level-based superovulation protocol with CIDR may be effectively used for production of superior embryos in Hanwoo. In other words, the less level of FSH may be effectively applied for Hanwoo (Korean Native Cattle), because Hanwoo was smaller body size than beef or daily cow.
