APPENDIX A

Proposed Reproductive Monitoring Program for Sungai Dusun’s Sumatran Rhino Breeding Centre

Goals of Ultrasonographic Reproductive Monitoring Program:

Information gained	Management Implications
Preovulatory follicle size (22 to 26 mm size at estrus)	Allows accurate prediction of estrus for accurate timed breeding
Ovulation documentation	Allows confirmation of normal female reprodutive function
Early pregnancy documentation	Ultrasound can provide a precise diagnosis of early pregnancy
Early embryo loss	Allows documentation of embryo loss and possible causes and allows for informed decisions regarding potential therapies
Pathology	Allows evaluation of pathology to facilitate management and medical decision-making

I. Ultrasound as a tool for enhanced breeding management

With our current understanding of Sumatran rhino reproductive function describing Dicerorhinus sumatrensis as an induced ovulator (Roth et. al., 2001), the use of ultrasound to predict impeding female receptivity, ovulation and timed breeding to a male will be, without question, fundamental to future captive reproductive management for this species. more »

Sumatran rhinos are the most endangered of the five rhino species. An estimated 300 individuals remain.

Sumatran Rhinos are the hairiest of the rhino species.
