We've had problems for several years with cattle on a certain group of pastures. Cattle develop photosensitization (crusting/peeling of white areas of skin). Usually only one animal is sick at any given time. This has only happened in adult animals - calves are okay. Bloodwork on one of the latest cases showed extremely high liver enzymes. These cattle have all recovered - treatment was to confine in a barn and antibiotics were given before we knew the cause was liver damage. I know liver damage can cause photosensitization, but does anyone know a likely cause of the liver damage? We live in SC, so liver flukes shouldn't be a problem.
