Review of Proposals to the Bureau of Land Management on Wild Horse and Burro Sterilization or Contraception: A Letter Report.

摘要

In 2011, BLM commissioned the National Research Council of the National Academy of Sciences to conduct an independent technical evaluation of the science, methodology, and technical decision-making approaches of the Wild Horse and Burro Program. Among the many tasks given the National Research Council’s study committee was evaluation of information related to the effectiveness of fertility-control methods to prevent pregnancies and reduce herd populations. For that topic, the Committee to Review the Bureau of Land Management Wild Horse and Burro Management Program evaluated the methods available on the basis of the criteria related to delivery method, availability, efficacy, duration of effect, and potential physiological and behavioral side effects. Considering those criteria, it judged porcine zona pellucida (PZP) and GonaCon? vaccination of females and chemical vasectomy in males as the most promising approaches.
