polioencephalomalacia

(pō'lē-ō-en-sef'ă-lō-mă-lā'shē-ă),
Cerebrocortical necrosis in sheep and goats, also seen in cattle, deer, and antelope. Associated with thiamine deficiency, water deprivation-sodium ion toxicosis, lead poisoning, and particularly with high dietary sulfur levels leading to high hydrogen sulfide and acetic acid levels in the rumen, which adversely affect carbohydrate metabolism.

THE most commonly seen nervous diseases of sheep are Listeriosis, CCN (cerebrocortical necrosis or polioencephalomalacia), gid (Sturdy or coenurosis) and vestibular disease (middle ear infection).
Less common problems causing recumbency are rupture of the prepubic tendon (when the belly drops to the ground), middle ear infections, cerebrocortical necrosis (CCN - a vitamin B1 deficiency) and lambs dying in the womb (toxaemia).
The symptoms are very similar to those of parturient paresis ("milk fever") seen prior to lambing, concentrate overload, cerebrocortical necrosis (CCN ( Vitamin B1 deficiency), copper poisoning and listeriosis.
