Abstract

An account is given of the autopsy findings in 78 piglets which died from iron poisoning. They belonged to an experimental series which included a further 6 piglets that also died but will not be accounted for here. The experiment was designed to study why iron treatment causes occasional deaths among piglets. The results will be reported in full elsewhere (Tollerz, in press).

In 63 piglets, the sows had been fed special experimental diets, and in 8 piglets from a field case where deaths occurred after conventional iron treatment to prevent anaemia, the predominant autopsy finding was waxy degeneration of the skeletal muscles, which appeared irrespective of whether iron dextran or iron dextrin was injected intramuscularly, or whether ferrofumarate or ferous sulphate was given orally. Only one piglet had slight heart-muscle degeneration, and hydropericardium was not present.

The remaining 7 piglets received ferrous sulphate orally, which resulted in catarrhal to necrotizing gastroenteritis. Three of these piglets had waxy degeneration of the skeletal muscles, but in the other 4 the musculature was intact, which indicates another mechanism of toxicity than that in the cases of muscle degeneration.
