Clinical signs of PEM can occur quite suddenly. Animals may be seen off by themselves, weak and may appear to be blind. Their necks may be found arched back over their bodies and will appear to be staring upwards. We call them “star gazers” or showing opisthotonus. They will appear to be disoriented and generally will not eat or drink well. They can have normal temperatures and respirations but decreased heart rates. They may simply be found down in their pen with the head thrown back and paddling as with seizures. Some may show head pressing and without treatment, may die as early as two days.
As devastating as the condition sounds, they will respond quite remarkably if treated quickly and in early onset.
