Abstract

The measurement of serum and urinary estrone sulfate (ES) was evaluated on random single samples for the detection of pregnancy in the Przewalski's horse (PRZ) and Hartmann's mountain zebra (HMZ). Pregnancy was detected by ES analysis of urine or serum in the PRZ and HMZ by at least 8 and 10 months before delivery, respectively. The values of ES in both serum and urine are shown at various stages of gestation. Results indicate urinary ES analysis is a noninvasive early diagnosis for pregnancy in these species.
