Multiparous Korean native cows were injected with 250㎍ of gonadotropin-releasing hormone(GnRH) on 14 days postpartum to investigate the effects of GnRH treatment on the period of the puerperium. The intervals between parturition and the first estrus were shorter (P$lt;0.025) in the treated cows(51.70 days) than the control cows(77.25 days). Although the intervals between parturition and conception became shorter by 8.7 days with the treatment (T=87.4 days v. C=96.1 days), there was no significant difference. Increased number of services per conception, lower rates of the first conception, and poorer ovarian conditions in the treated cows compared to the control cows were suggested as the reasons for no significant difference in the interval between parturition and conception between the two groups.
