The Australian ruminant livestock industries are faced with the need to control parasitic infectious diseases that can seriously impact the health of animals. However, increasing levels of resistance to insecticides, anthelmintics and acaricides are substantially reducing the ability to control some of these parasites. Here we review the current situation with regard to chemical resistances in parasites across the various sectors of the Australian ruminant livestock industries and assess the level of threat that these resistances pose to the sustainability of these sectors in the short to long terms. We also look at the extent to which testing for resistance occurs across the various industry sectors, and hence how well-informed these sectors are of the extent of chemical resistance. We examine on-farm management practices, breeding of parasite-resistant animals, and non-chemical therapeutics that may act as short to long term means to reduce the current reliance on chemicals for parasite control. Finally, we look at the balance between the prevalence and magnitude of current resistances and the availability and adoption rates of management, breeding and therapeutic alternatives in order to assess the parasite control outlook for the various industry sectors.
澳大利亚反刍动物养殖行业面临着控制寄生虫传染病的需求，这些传染病可能严重影响动物的健康。然而，杀虫剂、驱虫药和杀螨剂的耐药性水平不断提高，大大降低了控制部分寄生虫的能力。在这里，我们回顾了澳大利亚反刍动物养殖行业各个领域寄生虫的化学抗性现状，并评估了这些抗性在短期到长期内对这些行业可持续性构成的威胁程度。我们还研究了在各个行业领域进行抗性测试的程度，以及这些行业对化学抗性程度的了解程度。我们研究了农场管理实践、寄生虫抗性动物的繁殖以及可能作为短期到长期手段的非化学疗法，以减少目前对化学药品控制寄生虫的依赖。最后，我们研究了当前抗性的流行程度和幅度与管理、繁殖和治疗替代方案的可用性和采用率之间的平衡，以评估各个行业领域的寄生虫控制前景。
