Artificial insemination in the European hare (Lepus europaeus syriacus).

A simple technique for artificial insemination in hares was performed and used routinely in mass breeding of hares in captivity. Sperm was collected directly from the epididymides of males. Ovulation was induced by intravenous injection of human chorionic gonadotropin. Female hares were successfully inseminated throughout the year. Pregnancy occurred in 70% of inseminated females; the range in litter size was 1--3 offspring with a mean of 1.4. It was concluded that artificial insemination greatly simplified the breeding of hares in captivity.
