This study aimed to establish artificial insemination (AI) protocols to predictably initiate pregnancy during the breeding season in the European brown hare (EBH) (Lepus europaeus PALLAS, 1778). Semen was collected from seven captive and eight free-ranging males by means of electroejaculation. Semen from the free-ranging males was cryopreserved using directional freezing. Total motility/integrity of fresh and frozen-thawed semen was 91.6%/87.7% and 46.9%/53.8%, respectively. Ovulation was induced in ultrasonographically preselected females using a gonadotropin-releasing hormone analogue. Each female was inseminated with 1 mL fresh (Group A, n=16) or frozen-thawed semen (Group B, n=9) at a concentration of 100x10(6) spermatozoa/mL. The use of ultrasonography (10 to 22 MHz) confirmed the intracervical semen deposit, the success of artificial ovulation induction (formation of postovulatory corpus luteum), and permitted the monitoring of individual pregnancies. Although sperm motility/integrity was significantly different between groups, no significant difference was detected in conception rates (A, 87.50%; B, 77.78%). Because of embryonic resorption, there was a slight difference in fertility rate between groups (A, 62.5%; B, 77.78%). Overall, AI in captive EBH using fresh and frozen-thawed semen achieved successful fertility rates. Long-term cryopreserved semen was used to bring new genetic material from the wild into a genetically limited captive population without extensive animal transport. Therefore, AI has the potential to enhance breeding programs for EBH especially when cryopreserved semen from wild donors is used.
