Avigail the elephant undergoes an insemination process at the Biblical Zoo in Jerusalem. Avigail, an Asiatic elephant weighing about five tons, came to the zoo about four years ago. On November 9, sperm taken from an elephant in England was flown in, and on the day of Avigail’s ovulation period the insemination was performed, a process that took about an hour and a half. Several months later it turned out Avigail was not pregnant. An elephant’s pregnancy lasts 22 months.
