Hydrometra or pseudopregnancy is characterised by the accumulation of aseptic fluid within the uterus and a persistent corpus luteum. In goats the diagnosis can be easily made by ultrasound. The incidence of hydrometra was investigated in three herds of dairy goats, in two of them during one oestrous season and in the other over three years. The incidence varied between 3.0 per cent and 20.8 per cent with a mean incidence of 9.0 per cent. The incidence in older goats was significantly higher than in yearlings, and the chance of a hydrometra increased with the age of the goats. The finding, during one year, that a pseudopregnancy occurred more often after an induced ovulation, was not repeated in another year.
子宫积水或假孕的特征是子宫内无菌液体的积聚和黄体持续存在。在山羊中，通过超声检查很容易做出诊断。对三个奶山羊群的子宫积水发病率进行了调查，其中两个群在一个发情季节进行调查，另一个群在三年期间进行调查。发病率在3.0%至20.8%之间，平均发病率为9.0%。年龄较大的山羊发病率明显高于一岁羊，子宫积水的几率随着山羊年龄的增长而增加。有一年发现诱导排卵后假孕更常发生，但在另一年并未重复这一发现。
