Abstract

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.

GnRH 治疗对印度尼西亚小农农场中感染口蹄疫的奶牛卵巢功能紊乱的潜在解决方案的影响。

背景：目的：本研究旨在评估口蹄疫对奶牛繁殖性状的影响，并评估促性腺激素释放激素（GnRH）对口蹄疫感染奶牛繁殖性能的影响：研究在印度尼西亚中爪哇省 Boyolali 县 Taman Sari 分区的 Jemowo 村进行。共使用了 155 头奶牛来鉴定 2-10 岁感染口蹄疫的奶牛的繁殖障碍。奶牛的饲养条件和日粮相似。对 96 头卵巢失调奶牛肌肉注射单剂量 2 毫升 GnRH。繁殖性能通过每次受孕次数（S/C）、受孕率（CR）和妊娠率（PR）来衡量。研究采用描述性研究的方法来展示结果：研究表明，61.9% 的 FMD 感染奶牛存在繁殖障碍，其中卵巢功能低下占 53.5%，静默发情占 4.52%，重复配种占 1.94%，卵巢萎缩占 1.29%，子宫内膜炎占 0.65%。注射 GnRH 的 FMD 感染奶牛的繁殖恢复率为 98%。此外，注射 GnRH 的奶牛的 S/C、CR 和 PR 分别为 2.02%、51% 和 85%：结论：注射 GnRH 能提高感染 FMD 的奶牛的繁殖性能，表现在 CR 和 PR 的改善上。
