Monensin toxicosis in 2 sheep flocks.
Several lambs in 2 sheep flocks died suddenly and others were examined for generalized weakness and dyspnea. Postmortem findings were suggestive of degenerative myocardial and skeletal muscle myopathy, which was confirmed histologically. Feed analysis revealed toxic levels of monensin and ionophore toxicosis was diagnosed.
