Stuff reports a Dutch police helicopter diverts to roll a "cast" sheep back onto its feet.
Sheep get cast when they are on their back and cannot regain their feet and it is often made worse when stomach gas accumulates bringing death quite fast.
Often long wool sheep near shearing are more prone but the accompanying pics dispel that as a contributing factor.
Just off the coast of The Netherlands is the Island of Texel and a breed of sheep bearing that name were imported here in the late 1980s.
We farmed some as they had beautiful juicy fine grained meat, very succulent, a trait that transferred with crossing to create a great lamb carcass.
However, as a breed they were thick, often cast because they were to bloody lazy to get up.It often only took a cast by a heading dog to give the necessary impetuous for sufficient additional effort but alas, too often they just expired in situ.
