Dried, milled Cestrum laevigatum plant material was drenched to 6 ewes at doses ranging from 2,5 to 10 g/kg/day for 1 to 47 days. The most noticeable clinical signs were depression, anorexia and ruminal stasis. These signs were accompanied by clinical pathological changes indicative of liver involvement such as increases in the serum activities of aspartate transaminase, lactate dehydrogenase and gamma-glutamyltransferase. Hepatosis characterized by accentuated lobulation, and centrilobular to midzonal coagulative necrosis, haemorrhage and congestion occurred in 2 of the 3 ewes given high doses of plant material. Liver lesions in the other animals included disappearance of hepatocytes and collapse of the reticulin stroma in the centrilobular areas. Spongy changes in the cerebral white matter were evident in the ewes of the high-dose group. Ultrastructural changes in the liver comprised degeneration and necrosis of hepatocytes and occasionally endothelial cells, and disruption of sinusoidal walls.

Rapeseed meal hepatosis was produced by feeding high and low glucosinolate meals as a source of protein (about 200 g kg-1 diet) but could not be distinguished histologically from fatty liver-haemorrhagic syndrome which occurred in birds on the control diet. Both types of meal increased haemorrhage, reticulolysis and lymphoproliferation in the liver, reduced the packed cell volume and caused thyroid enlargement. Haemorrhages emanated from ruptured intrahepatic portal veins, capillaries and sinusoids and were associated with degenerative changes in vessel walls. Haemorrhage and reticulin scores were correlated. Parenchymal necrosis occurred only around large haematomas and caused increased aspartate transaminase activity in the plasma. Both meals also caused hyperglycaemia and reduced the plasma triglyceride content. Only the high glucosinolate meal decreased egg production, caused liver enlargement and reduced the plasma urate level. The addition of myrosinase enhanced its effects on egg production and packed cell volume but did not increase its hepatotoxicity.
