Poisoning Associated with Ingestion of Redroot Pigweed (Amaranthus retroflexus) in Cattle – Case Report

Abstract

On a farm in Slovenia two cows died overnight without any previous signs of disease. The cows were fed green forage, containing a big portion of redroot pigweed (Amaranthus retroflexus) at least for four consecutive days. Poisoning with this plant was suspected. Pathomorphological changes established by the necropsy of both cows confirmed the suspi- cion of poisoning.
