  Title Pregnancy Determination in Uncaptured Feral Horses Type Journal Article
  Year 1988 Publication (down) Journal of Wildlife Management Abbreviated Journal J Wildl Manag  
  Volume 52 Issue 2 Pages 305-308  
  Keywords  
  Abstract The urinary excretion of estrone sulfate ($\text{E}{1}\text{S}$) by 25 free-roaming feral horses (Equus caballus) was measured by radioimmunoassay applied to extracts of urine-soaked soil. Twelve of 15 mares having $\text{E}{1}\text{S}$ concentrations >1.0 mg/mg creatinine (x = 2.64 +- 1.02 [SD]) produced foals. All 10 mares with $\text{E}{1}\text{S}$ concentrations <1.0 mg/mg creatinine (x = 0.44 +- 0.26) did not foal. Extracting urine from soil and measuring $\text{E}{1}\text{S}$ and creatinine can be used to determine pregnancy in free-roaming feral horses without the stress of capture or immobilization.

  Title Testis size and onset of spermatogenesis in Cape mountain zebras (Equus zebra zebra) Type Journal Article
  Year 1988 Publication (down) Journal of Reproduction and Fertility Abbreviated Journal J Reprod Fert  
  Volume 83 Issue Pages 371-375  
  Keywords mountain zebra; testis size; spermatogenesis  
  Abstract Testis mass of adult Cape mountain zebra stallions (mean 70·0 g) was appreciably less than that of other zebra species and domestic horses. The histological appearance of the testes of 11-, 24- and 29-month-old colts was typically prepubertal. Spermatogenic activity of a 4-year-old stallion obtained at the end of summer was at a very low level, while a 4·5-year-old stallion obtained 6 weeks after the winter solstice showed a marked increase in spermatogenesis compared with the 4-year-old. Stallions 6·5-19 years of age collected in different seasons all showed active spermatogenesis.

  Title Reproduction in female Hartmann's zebra Type Journal Article
  Year 1988 Publication (down) Journal of Reproduction and Fertility Abbreviated Journal J Reprod Fert  
  Volume 84 Issue Pages 505-511  
  Keywords zebra; reproduction; ovaries; seasonality; progesterone  
  Abstract Ovaries, fetuses and plasma were collected from zebra mares shot in the Etosha National Park in Namibia between 15 and 25 August 1983. Ovarian weight was affected by reproductive status and most of the non-pregnant mares were anoestrous. The number of follicles varied between individuals and only pro-oestrous/oestrous mares had follicles larger than 20 mm in diameter. The largest follicle in pregnant mares was only 9 mm in diameter. Corpora lutea and corpora albicantia were found in non-pregnant as well as pregnant mares: 4 pregnant mares had only corpora albicantia. The presence of secondary corpora lutea could not be confirmed in any of the pregnant mares. Implantation was estimated to occur at around 73 days of gestation, and most mares (84%) had conceived between November and April. Peripheral concentrations of plasma progesterone during pregnancy varied from 0·5 to 2·4 ng/ml.
