Thread: 100 Dairy cows Pb poisioned at Southland clay club

I'm afraid lead poisoning in cattle is real (sheep and dogs too).

Pathogenesis
Absorbed lead enters the blood and soft tissues and eventually redistributes to the bone. The degree of absorption and retention is influenced by dietary factors such as calcium or iron levels. In ruminants, particulate lead lodged in the reticulum slowly dissolves and releases significant quantities of lead. Lead has a profound effect on sulfhydryl-containing enzymes, the thiol content of erythrocytes, antioxidant defenses, and tissues rich in mitochondria, which is reflected in the clinical syndrome. In addition to the cerebellar haemorrhage and oedema associated with capillary damage, lead is also irritating, immunosuppressive, gametotoxic, teratogenic, nephrotoxic, and toxic to the hematopoietic system.

In cattle, surgery to remove particulate lead material from the reticulum after the ingestion of batteries is rarely successful.

Suspiciously, I found a heap of spelling errors in the article!? Maybe vets just can't spell or don't know about spell checkers.
