[Behavior of neutral 17-ketosteroids in the urine of female pigs].
Ketosteroids were determined colorimetrically in samples of 24-hour urine from sows, ten days after service. Pregnancy was diagnosed by injection of the "Gravignost-swine" preparation in eight sows. Significant differences between the 17-ketosteroid excretion on non-pregnant sows were revealed by the excretion in 24-hour urine, but not by urinary concentration expressed in mg per litre. Injection of "Gravignost" had no effect on 17-ketosteroid values. In pregnant sows the urinary concentration of 17-ketosteroids was inversely proportional to daily urine volume, and there was also a significant correlation between urine volume and 17-ketosteroid excretion expressed in mg per 24 hours. The method used for determining urinary ketosteroids was sufficiently reliable and simple to be used for routine testing.
