This photograph is a sheep.
There are three or four major lesions in this photograph, in addition to the dirty fingernails and bare hands. What are they?
You are probably in good shape in thinking what the etiology is here.
Does rinderpest do this to sheep? How about sheep pox?
There is also a disease of small ruminants that resembles rinderpest. You might review it.
Is this a hairy shaker?
Actually there is only one lesion - erosion. It is present on the nose, lips, and dental pad.
Here is the serratus muscle from the same sheep as viewed above.
Note the pink or cream-colored streaks in this skeletal muscle. The streaks represent degeneration and necrosis of skeletal muscle.
Sheep are frequently afflicted with nutritional muscle dystrophy/selenium-vitamin E deficiency/white muscle disease. So it would not be smart to have this muscle lesions stand alone. If it were the only lesion visible, then serious consideration would have to be given to nutritional myopathy.
However, this particular lesion, being from the previous case, likely represents a blue-tongue myopathy.
If, after examining these two lesions your are still uncertain, then you can look at the next photograph and resolve the dilemma.
