Once plants containing cyanide have been consumed, the toxin rapidly enters the blood stream and is transported throughout the body of the animal. Plant cells can be ruptured by cutting, wilting, freezing, drought, crushing, trampling, chewing or chopping.

These cyanogenic compounds are in epidermal cells (outer tissue) of the plant, while the enzymes that enable cyanide production are in the mesophyll cells (leaf tissue).Īny event that causes the plant cell to rupture, allowing the cyanogenic compound and the enzyme to combine, will produce cyanide. Sorghums and related species readily accumulate these compounds. Prussic acid poisoning in a chicken flock.A number of common plants may accumulate large quantities of cyanogenic compounds. Sodium nitroprusside, a convenient source of dietary cyanide for the study of chronic cyanide toxicity.

Poisonous properties of wild cherry leaves. Reduced selenium status in chicks given diets low in sulphur-containing amino acids and containing sodium nitroprusside as a source of cyanide. Cyanide poisoning in animals and humans: a review. Kingston, R A rational guide to plant toxicity.

Effect of feeding cassava (Manihot esculenta Crantz) root meal on growth performance, hydrocyanide intake and haematological parameters of broiler chicks. Akapo AO, Oso AO, Bamgbose AM, Sanwo KA, Jegede AV, Sobayo RA, Idowu OM, Fan J, Li L, Olorunsola RA.Drought and dry growing conditions enhance the accumulation of cyanogenic glycosides in many of these plants as well. The amount of cyanide present in these plants are highly variable, but are typically highest during the spring while blooming. Although the blood is highly oxygenated and therefore a characteristic bright cherry red color, oxygen delivery to the tissues is poor and the bird becomes severely hypoxic.Ī number of different plants can accumulate cyanogenic glycosides. Cyanide acts almost instantly, and can cause death within a few seconds to minutes.Ĭyanide combines with iron in cytochrome oxidase, preventing terminal electron transfer and blocking cellular respiration. Cyanide prevents the cells of the body from using oxygen.

Cyanide poisoning can occur through exposure to fumes from fires, or ingestion of certain common foods, plants, or products containing cyanide or cyanogenic glycosides. Cyanide is a rapidly acting, deadly chemical that is highly toxic to chickens.
