Sometimes sheep get sick and despite our best efforts fail to recover. This recently occurred with a sheep that had a name: "Rosie". She was very thin and was vomiting up feed. We wormed her and gave her a course of antibiotics, still no improvement. Today, we took her to visit our friend the vet. Nothing obvious was found on examination, and she was euthanized. Then he conducted an autopsy: she had a scarred oesophagus which had seriously constricted to pencil thickness. Impossible to fix as it was between the diaphragm and the throat. Also difficult to determine the cause. But would have caused her a long slow death .
