To describe the epidemiology of cystic ovarian disease (COD), to find possible risk factors associated with the incidence of cysts and to analyse the impact of COD on the reproductive performance of dairy cows, databases from 22 dairy herds from the main dairy region in Argentina were retrospectively evaluated throughout a 3-year period (2009-2011). A total of 248 COD cases over 9156 parturitions were recorded, resulting in a cumulative incidence rate of 2.7%. Cystic ovarian disease incidence density was lower during the first 100 days post-partum (DPP) than during later stages of lactation. Seasonality had a significant influence on the disease presentation with higher incidence rates during winter and spring. Cows with a previous diagnosis of clinical mastitis showed 2.72 times more chances of developing ovarian cysts. Cystic cows had longer calving to first service and calving to conception intervals and lower conception rate than controls.
为描述卵巢囊肿疾病（COD）的流行病学特征，寻找与囊肿发病率相关的可能风险因素，并分析COD对奶牛繁殖性能的影响，对来自阿根廷主要奶牛养殖区22个奶牛场的数据库进行了为期3年（2009 - 2011年）的回顾性评估。在9156次分娩中，共记录了248例COD病例，累积发病率为2.7%。产后前100天（DPP）的卵巢囊肿发病率密度低于泌乳后期。季节性对疾病表现有显著影响，冬季和春季发病率较高。先前诊断为临床乳腺炎的奶牛发生卵巢囊肿的几率高出2.72倍。与对照组相比，患囊肿的奶牛从产犊到首次配种以及从产犊到受孕的间隔时间更长，受孕率更低。
