Immunocontraception of African elephants

Nature volume 407, page 149 (14 September 2000) | Download Citation



Concerted efforts to nurture elephant populations have resulted in elephant overpopulation in several areas, which in turn has led to damaging levels of browsing. As an alternative to culling entire family groups in order to control this damage, we have developed an immunocontraceptive vaccine from pig zona pellucida which safely and successfully controls free-roaming African elephants.

A humane method to control elephant populations without behavioural side effects.
