Abstract
Studies of Asian elephant reproduction at the Washington Park Zoo in the areas of the estrous cycle, semen collection, bull elephant management and health care, pregnancy, and pheromones have yielded sufficient information to attempt repeated artificial insemination (AI) at the time of ovulation. While no pregnancy has been achieved to date, with the information now at hand AI can be expected to become a practical technique for breeding elephants in captivity.
