Suspected Iron Toxicity in Dairy Cattle
Öz
Seven dairy cattle died in a farm in Ivrindi, Balıkesir, Turkey. Local veterinary practitioner reported that all affected animals showed anorexia, depression, orange-yellow discoloration of buccal mucosa and lips, abdominal pain and dyspnoea. Postmortem lesions were orange-yellow discoloration of blood and all tissues, dark and degenerate liver, dark and oedematous kidneys. All feed and feed materials of dairy cattle were analysed for iron. High level (1992 mg/kg) of iron was detected in commercial dairy feed additive. Iron toxicities in dairy cattle by oral route are very rare and we could not find any published report. In this case, historical and clinical signs, postmortem findings and the detection of high level of iron in the feed additive supported a diagnosis of subacute to/or chronic iron toxicity in dairy cattle by oral route.
