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.
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.
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.
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%.
GnRH administrations enhanced the reproductive traits of FMD-infected dairy cows indicated by the improvement of CR and PR.
印度尼西亚口蹄疫（FMD）的爆发导致奶牛生殖紊乱，给奶牛养殖者造成经济损失。
评估口蹄疫对奶牛生殖性能的影响，并评估促性腺激素释放激素（GnRH）对感染口蹄疫奶牛生殖性能的影响。
本研究在印度尼西亚中爪哇省博约拉利县塔曼萨里区杰莫沃村进行。共对 155 头 2-10 岁的奶牛进行了研究，以确定感染口蹄疫奶牛的生殖障碍。奶牛饲养条件和饲料相似。对 96 头卵巢功能障碍奶牛进行了 GnRH 肌肉注射（每头 2ml）。受孕服务率（S/C）、受孕率（CR）和妊娠率（PR）用于评估奶牛的生殖性能。采用描述性研究方法展示结果。
研究表明，61.9%的感染口蹄疫奶牛出现生殖障碍，其中 53.5%卵巢功能低下，4.52%隐性发情，1.94%屡配不孕，1.29%卵巢萎缩，0.65%子宫内膜炎。注射 GnRH 的感染口蹄疫奶牛的生殖恢复率达到 98%。此外，注射 GnRH 的奶牛的 S/C、CR 和 PR 分别为 2.02%、51%和 85%。
GnRH 处理提高了感染口蹄疫奶牛的繁殖性能，表现为受孕率和妊娠率的提高。
