In a sowherd suffering from high incidence of MMA which demanded an intensive postparturient treatment to reduce baby pig mortality the effect on postparturient diseases of induction of parturition with Prostaglandin was examined. After treatment of 19 sows on day 112 of gestation with 12.5 mg Prostaglandin, parturition in 15 sows took place on an average of 25 hours after injection; the gestation period was 113.1 +/- 0.5 days. Three sows that did not respond to the treatment farrowed 3-6 days after treatment and one sow farrowed few hours after treatment. In a non-treated identical group of animals the gestation period averaged 113.4 +/- 1.5 days. No difference was found between the two groups concerning number of stillborn pgis, baby pig mortality within first eight days of life, incidence of MMA or intensity of postparturient medical treatment.
在一个患有高发病率 MMA（母猪无乳综合征）且需要强化产后治疗以降低仔猪死亡率的猪场，研究了用前列腺素引产对产后疾病的影响。在妊娠第 112 天，用 12.5 毫克前列腺素对 19 头母猪进行治疗后，15 头母猪平均在注射后 25 小时分娩；妊娠期为 113.1±0.5 天。3 头对治疗无反应的母猪在治疗后 3 - 6 天产仔，1 头母猪在治疗后数小时产仔。在未治疗的相同动物组中，妊娠期平均为 113.4±1.5 天。两组在死产仔猪数量、出生后前八天的仔猪死亡率、MMA 发病率或产后医疗治疗强度方面均未发现差异。
