A form of hepatogenous copper poisoning in fattening cattle associated with the ingestion of mouldy straw

Abstract: Two bulls from a group of 85 fattening bulls and heifers were examined postmortem. Both had generalised jaundice, swollen pale brown livers, dark brown kidneys and dark brown urine in the bladders. Biochemical testing of the livers and kidneys was indicative of copper poisoning in the two animals. Histopathology identified necrotising hepatopathy, consistent with an acute haemolytic crisis, superimposed on liver lesions of longer duration, which were suggestive of another toxic aetiology. Analysis of the anima… Show more

“…Copper poisoning in cattle is rare, but acute cases have been reported, particularly in calves (Bradley 1993 ; Minervino et al 2009 ). According to Otter et al ( 2023 ), cattle may be more susceptible to copper poisoning if they have underlying hepatic damage. Copper poisoning can be divided into two phases: an accumulation phase, during which copper is stored in the liver, and a phase of acute illness.…”
