Abstract
The serow ( Capricornis sumatraensis) is a critically endangered species. The objectives of this study were to evaluate ejaculate quality in captive males, and to investigate and characterize sperm morphology. Semen was collected using electroejaculation. Mean (±S.D.) seminal characteristics were: semen volume 2.3 ± 0.8 mL, pH 7.8 ± 0.4, and osmolality 329.9 ± 32.9 mOsmol/kg; sperm concentration 515.8 ± 263.1 × 10 6 cells/mL; wave motion score (1–5) 3.9 ± 0.4; motile sperm 60.5 ± 22%; viable sperm 68.3 ± 9.4%; morphologically normal sperm 70.8 ± 19.3%; and an opacity that was yellowish to milky-white. Sperm head length, width, degree of elongation, area, and perimeter were 6.0 ± 0.6 μm, 4.3 ± 0.3 μm, 71.7 ± 8.6%, 19.8 ± 2.5 μm 2, and 17.9 ± 2.1 μm. Based on these measurements, we categorized sperm head morphometry as small, medium, or large. In addition, sperm morphology was examined by light and scanning electron microscopy; overall, morphologically normal and abnormal sperm were similar to those reported for other bovidae. In summary, this study provided baseline data regarding semen characteristics of C. sumatraensis, which should be of value in the preservation of this endangered species.
