Photosensitisation in lambs associated with ingestion of bog asphodel (Narthecium ossifragum)
Bog asphodel (German: Beinbrech; Åhrenlilie; Moorlilie; or Gelbe Moorlilie) is a perennial plant of the family Liliaceae and is common on wet heaths, bogs and moorland in North-West Europe (Cooper and others, 2003). It has slightly fleshy grass-like leaves, flattened into one plane and 15 to 30 cm long stems bearing a slender raceme of bright yellow flowers approximately 1 cm in diameter during summer (Figure 1). Bog asphodel poisoning is associated with a hepatogenous photosensitisation in lambs, which is known as “yellowses” or “plochteach” in Scotland (Pollock and others, 2015). The condition is known as “alveld” in Norway (Ender, 1955), where it has been extensively researched and is regarded as an important sheep health issue (Ulvund, 2012). Bog asphodel does not cause photosensitisation in cattle; instead it is associated with kidney disease (Malone and others, 1992).
