摘要：

This study details the seminal traits in the rare Asiatic black bear, revealing that this species generally produces high quality, concentrated ejaculates containing sperm of high motility and morphological integrity and similar to other members of the Ursine lineage. Semen was collected by electroejaculation and 23 trials were performed on 18 bears. The mean values were obtained for volume (0.61 ml), pH (7.1), sperm concentration (1049 x 10(6) ml(-1)), total sperm counts (502.8 x 10(6)), motility percentage (63.8%), forward progressive status (3.5), abnormal sperm percentage (37.9%) and intact acrosome percentage (76.6%).
