| Abstrakt: | Background: The outbreak of foot and mouth disease (FMD) in Indonesia induces reproductive disorders in dairy cows that lead to economic losses to smallholder dairy farms. Aim: The study was to assess the influence of FMD on reproductive traits and evaluate the effect of gonadotropin hormone-releasing hormone (GnRH) administrations on the reproductive performance in FMD-infected dairy cows. Methods: The study was conducted in Jemowo village, Taman Sari sub-district, Boyolali district, Central Java, Indonesia. A total of 155 cows were used to identify the reproductive disorders on FMD-infected dairy cows aged 2-10 years old. Cows were raised in similar conditions and fed diets. A single dose of 2 ml GnRH was injected intramuscularly into 96 ovarian disorder cows. Reproductive performance was measured by service per conception (S/C), conception rate (CR), and pregnancy rate (PR). A descriptive study was conducted to demonstrate the results. Results: The study showed that 61.9% of FMD-infected cows had reproductive disorders, whereby 53.5% ovarian hypofunction, 4.52% silent heat, 1.94% repeat breeder, 1.29% ovarian atrophy, and 0.65% endometritis. FMD-infected cows injected with GnRH had a 98% reproductive recovery rate. Moreover, the S/C, CR, and PR of cows injected with GnRH were 2.02%, 51%, and 85%. Conclusion: GnRH administrations enhanced the reproductive traits of FMD-infected dairy cows indicated by the improvement of CR and PR.
