A loss of genetic diversity may be a major problem facing domestic breeds of livestock, such as Canadian Holstein cattle, and wild indigenous species such as wood bison. In domestic livestock, the emphasis on a few breeds or genetic lines within breeds, to satisfy the demands of the market, intensifies the problem. In Canada's threatened wood bison, a lack of genetic diversity is a consequence of historical over-harvesting and endemic diseases transmitted from cattle. This workshop will bring together experts from industry, government, and academia to determine if inbreeding and loss of genetic diversity really are a cause for concern. It will also identify risks associated with a loss of diversity and create strategies and guidelines to initiate the maintenance of diversity among species such as Canada's Holstein and wood bison. Lastly, participants will identify technologies that may be required to monitor and prevent loss of diversity, and create new research partnerships on reproductive strategies to address this situation.

遗传多样性的丧失可能是国内家畜品种面临的一个主要问题，如加拿大 荷斯坦牛，以及野生土著物种，如林野牛。在家畜方面，重点放在几个方面 品种或品种内的遗传系，以满足市场需求，加剧了问题。在加拿大的 受到威胁的森林野牛，缺乏遗传多样性是历史上过度捕捞和地方性疾病的结果 由牛传播的疾病。这次研讨会将汇聚来自行业、政府和 学术界正在确定近亲繁殖和遗传多样性的丧失是否真的令人担忧。它还将 识别与多样性丧失相关的风险，并制定策略和指导方针以启动维护 物种之间的多样性，如加拿大的荷斯坦和森林野牛。最后，参与者将确定 可能需要的技术，以监测和防止多样性的丧失，并创造新的研究 在生殖战略方面建立伙伴关系，以解决这一情况。
