对牲畜进行大环内酯处理可能会对牲畜粪便中的节肢动物种群产生有害影响。在过去的二十年里，英国皇家鸟类保护协会 (RSPB) 管理野生动物的畜牧场一直建议避免使用这些产品。然而，苏格兰内赫布里底群岛岛屿上依赖粪便无脊椎动物的鸟类（特别是红嘴山鸦 Pyrrhocoraxpyrrhocorax）数量持续下降，促使我们调查这些岛屿上常用的牲畜治疗方法的影响。我们进行了两年多的重复田间小区研究，以量化含有铜、溴氰菊酯和三氯苯达唑的家畜处理对艾莱岛人工粪便池中无脊椎动物密度的影响。我们发现，三氯苯达唑和溴氰菊酯治疗在这两年中节肢动物幼虫的密度均显着降低，而联合治疗时节肢动物幼虫的密度可降低高达 86%。含铜丸剂并不总是影响节肢动物幼虫的丰度。这些结果表明，对牲畜进行兽医治疗可能会导致山鸦食物供应的减少。
Macrocyclic lactone treatments for livestock can have detrimental effects on the arthropod populations in livestock faeces. For the last twenty years, avoidance of these products has been a standard recommendation on livestock farms that are managed for wildlife by the Royal Society for Protection of Birds (RSPB). However, the continued decline in the populations of birds (in particular the red-billed chough Pyrrhocorax pyrrhocorax) that are dependent on dung invertebrates on islands in the Inner Hebrides of Scotland prompted us to investigate the effects of livestock treatments that are commonly used on these islands. We conducted a replicated field plot study over two years to quantify the effects of livestock treatments containing copper, deltamethrin and triclabendazole on invertebrate density in pooled, artificial faecal pats on the island of Islay. We found that the density of arthropod larvae was significantly reduced by the triclabendazole and deltamethrin treatments in both years and by as much as 86% when the treatments were combined. Copper-containing boluses did not consistently affect abundance of arthropod larvae. These results suggest that veterinary treatment of livestock might contribute to a reduction in the food supply of chough.
