Original text on this topic:
It has been successfully applied to the rhinoceros. Direct massage of the penis begins with slow stroking that proceeds to vigorous massaging by the operator until the rhinoceros ejaculates. Rhinoceroses are the most receptive to this procedure and therefore it has been the method most frequently used. It is also the easiest to apply. This method was immediately successful in two black rhinoceroses, however, in two white and two Indian rhinoceroses, protracted periods of training were required. For instance, ten months of training were required to obtain seminal fluids with significant sperm counts in one Indian rhinoceros. However, with further conditioning with penile massage, this animal began to ejaculate fluids that contained sperm concentrations in the billions. This method can be successful within a short period in high libido and cooperative rhinoceroses. In less receptive animals, the procedure will take more training, but the results can be highly productive.
