 | | Here we describe a feeding trial with Blackface sheep conducted on an organic farm in Kintyre (Scotland), which aims to prove that the metabolism of arsenic, acquired from the consumption of seaweed, is not unique to the North Ronaldsay sheep, which are adapted to a seaweed diet. |
 | | The sheep are a rare ancient breed of primitive sheep and their diet consists entirely of seaweed, principally Laminaria digitata, as the sheep have been forced to live on the beach for centuries and are prevented from grazing on grass further inland by a high wall that surrounds the island. |
 | | Although the average arsenic liver concentration of the Blackface sheep is a factor of two lower than that of the North Ronaldsay sheep, their arsenic intake is a factor of 20 lower. |
