ABSTRACT

Background:

Cyanogenic plants accumulate cyanogenic glycosides and release hydrocyanic acid (HCN). In Brazil, therehave been reports of several plants that cause HCN poisoning in animals and lead to a fast death with few clinical signs andlesions on post mortem examination. Some cultivars of Cynodon spp. grasses cause HCN poisoning in cattle in Brazil. Theobjectives of this work were to report the occurrence of deaths by HCN poisoning in cattle as diagnosed by the veterinarypathology laboratory, describe the quantity of HCN in some cultivars of Cynodon spp., as well as, to describe one cultivarof genus Cynodon never reported as poisonous.Materials, Methods &

Results:

The archives of the Veterinary Pathology Laboratory (LPV) at the Concórdia Campus ofthe Instituto Federal Catarinense (IFC) were reviewed, seeking cases with a diagnosis of hydrocyanic acid poisoning incattle after post mortem examination. The amount of HCN present in some cultivars of the Cynodon genus was quantified due to the high frequency of poisoning cases. From the 1,235 post mortem examinations of cattle 28 (2.27%) werediagnosed with spontaneous hydrocyanic acid poisoning, 17 cases (60.7%) due to ingestion of Prunus sp. or Manihotsp., and 11 cases (39.3%) of Cynodon dactylon ingestion. Most animals were found dead, normally having presented noclinical signs. Macroscopic evaluation mainly showed a severe amount of unchewed and undigested leaves or grass mixedin the ruminal content presenting a bitter almond odor. It was possible to infer that, among cultivars of the Cynodon genus, Florakirk showed the highest levels of HCN compared (P < 0.05) with Star of Puerto Rico, Tifton 68, Tifton 44, andCoast-Cross. Furthermore, Tifton 85 and Jiggs showed undetected levels of HCN...
