Previous experiments with bromocriptine suggested that prolactin plays a role in the aetiology of pseudopregnancy in goats. Serum prolactin concentration was measured in a herd of white Dutch dairy (Saanen) goats when hydrometra (a typical characteristic of pseudopregnancy) was diagnosed by ultrasound, during the spontaneous development of pseudopregnancy, and in normally reproducing goats during the breeding season. In the normally reproducing does the prolactin concentration decreased at the beginning of the breeding season. In 12 of 14 pseudopregnant goats the prolactin concentration was within the range observed in the normally reproducing goats on the day that hydrometra was diagnosed. In two goats the prolactin concentration was low during the first few weeks of pseudopregnancy and in a third it fluctuated. There was no correlation found between the concentration of prolactin and the development or the presence of a persistent corpus luteum. These results suggest that prolactin does not play a crucial role in the aetiology of pseudopregnancy in the goat.
先前使用溴隐亭进行的实验表明，催乳素在山羊假孕的病因学中起作用。在一群白色荷兰奶牛（萨能）山羊中，当通过超声诊断出积水子宫（假孕的一个典型特征）时、在假孕的自然发展过程中以及在繁殖季节正常繁殖的山羊中，测量血清催乳素浓度。在正常繁殖的母羊中，催乳素浓度在繁殖季节开始时下降。在14只假孕山羊中的12只中，在诊断出积水子宫的当天，催乳素浓度处于正常繁殖山羊中观察到的范围内。在两只山羊中，假孕的最初几周催乳素浓度较低，在第三只山羊中其浓度波动。未发现催乳素浓度与持久黄体的发育或存在之间存在相关性。这些结果表明，催乳素在山羊假孕的病因学中不发挥关键作用。
