Pigweed (Amaranthus retroflexus L.) is one of the common weeds that grow in northwest of Iran. Pigweed poisoning was reported in cattle, sheep and pigs from United States, Canada, Brazil and Israel. This study was conducted to assess the clinical signs, clinical pathology and pathological findings in experimental pigweed poisoning in calves. Ten native calves aged 5 to 7 months were divided into two groups (experiment and control groups). The plant was collected from farms and fed to calves. One calf of experimental group died, without showing any clinical signs on day 38. Statistical analysis revealed an increase of serum creatinine, BUN, sodium and GGT. The significant elevation of creatinine, BUN and sodium indicated possible lesions ofkidneys and of GGT might be indicative of hepatic lesions. Remarkable histopathological lesions were seen in liver, kidneys, lymph nods, heart and nervous system.
