|
This study was conducted to investigate the effects of various estrus synchronization and seasonal breeding in Hanwoo. Delivery interval and number of service per conception were 412.9 and 1.76 in the annual breeding and 376.59 and 1.48 in the seasonal breeding, respectively. The percentage of cows exhibiting estrus in PG F_{2{alpha}}, PRID, CIDR and CnRH-PG F_{2{alpha}}-GnRH were 68.1%(141/207), 71.42%(15/20), 56.8%(33/38) and 93.1%(216/232), respectively. A greater percentage of GnRH-PG F_{ 2{alpha}}-GnRH treatment became pregnant(91.1%) than across all treatments(75.0%, 81.0%, 89.6%). The results show that GnRH-PG F_{2{alpha}}-GnRH treatment f3r pregnant in Hanwoo seems to be more effective than the others.
