Reproductive and urinary tract abnormalities are a cause of infertility, reproductive inefficiency, and economic losses in goats. The aim of this study was to investigate the occurrence and nature of reproductive and urinary tract abnormalities encountered in female goats slaughtered at Nyagatare abattoir in the Eastern Province of Rwanda. Reproductive and urinary organs from 369 female goat carcasses were opened by incision and then given a thorough macroscopic examination by visually inspecting and palpating for evidence of abnormalities. The results showed that there was an overall occurrence of 7.8% reproductive organ/tract abnormalities and 10.6% urinary organ/tract abnormalities. Ovarian hypoplasia was the reproductive abnormality with the highest overall occurrence (32.3%) and renal calculi were the urinary organ abnormality with the highest occurrence (38.1%). 95.2% of the reproductive organ/tract abnormalities observed usually result in infertility and 91.3% of the urinary organ/tract abnormalities observed result in economic losses through condemnation of kidneys at slaughter. The high incidence of the observed urinary organ/tract abnormalities represents a potential public health challenge. There was no significant difference in the occurrence of reproductive organ/tract abnormalities according to breed ( > 0.05, = 31). There was also no significant difference in the occurrence of urinary organ abnormalities according to breed ( > 0.05, = 42).
生殖和泌尿道异常是导致山羊不育、繁殖效率低下和经济损失的原因。本研究的目的是调查在卢旺达东部省尼亚加塔雷屠宰场宰杀的雌性山羊中生殖和泌尿道异常的发生情况及性质。对369具雌性山羊尸体的生殖和泌尿器官进行切开，然后通过目视检查和触诊对是否存在异常迹象进行全面的宏观检查。结果显示，生殖器官/生殖道异常的总体发生率为7.8%，泌尿器官/泌尿道异常的总体发生率为10.6%。卵巢发育不全是总体发生率最高的生殖异常（32.3%），肾结石是发生率最高的泌尿器官异常（38.1%）。观察到的95.2%的生殖器官/生殖道异常通常会导致不育，91.3%的观察到的泌尿器官异常会因屠宰时肾脏被判定不合格而造成经济损失。观察到的泌尿器官/泌尿道异常的高发生率代表了一个潜在的公共卫生挑战。根据品种，生殖器官/生殖道异常的发生率没有显著差异（>0.05，自由度=31）。根据品种，泌尿器官异常的发生率也没有显著差异（>0.05，自由度=42）。
