Continuous gentle massage of the penis caused the rhino to ejaculate after about 15 minutes. On different occasions from 3 to 15 ml of semen was collected successfully with this technique.
The semen was yellowish, slightly alkaline, and had the consistency of cow milk. Microscopic examination of the samples revealed numerous dead spermatozoa, neutrophiles and squamous epithelium cells. The semen was obviously of poor quality, but better results might be expected once the bull had become used to the procedure.
