	Prussic Acid Poisoning
		A characteristic sign of prussic acid toxicity is bright cherry-red blood, a symptom that persists several hours after death.
		Treatment of prussic acid poisoning, with a mixture of sodium nitrate and sodium thiosulfate or with methylene blue, can be successful if administered by a veterinarian soon after symptoms appear.
		Prussic acid (HCN) causes acute poisoning in ruminants grazing sorghums, especially johnsongrass.

	Forage Information
		Prussic acid is released very quickly from the glucoside form in frozen leaves, and hence frosted sorghum is very dangerous until it begins to dry out.
		Prussic acid is released very quickly from the glucoside form in frozen leaves, and hence frosted sudangrass can be very dangerous until it has dried out.
		Prussic acid is present in appreciable amounts only in the rapidly growing part of the plant, which is a very small portion of a plant 18 inches or more in height.

	ZUNDELSITE - LEUCHTER REPORT - APPENDIX III
		Prussic acid may not be brought into contact with an open flame, glowing wires, etc. because then it burns up slowly and loses all its effectiveness (carbonic acid, water and nitrogen are formed).
		ZYKLON is the absorption of a mixture of prussic acid and an irritant by a carrier.
		The toxicity of the prussic acid remains unchanged by the addition of the irritant; the danger connected with it is however considerably decreased.

	Caution Statements (Site not responding. Last check: 2007-09-17)
		Prussic acid (HCN) or hydrogen cyanide has long been recognized as a potentially devastating problem in the pasturing of livestock on sorghum forage.
		Prussic acid is concentrated in new growth of leaves and shoots.
		Prussic acid dissipates as the forage lies in the windrow and studies have shown that the ensiling process reduces the prussic acid level by 50% to 80%.

	Prussic acid poisoning in livestock (Site not responding. Last check: 2007-09-17)
		Prussic acid is not normally present in plants; however, under certain conditions, several common plants can accumulate large quantities of cyanogenic glycosides which can convert to prussic acid.
		Prussic acid is a potent, rapidly acting poison, which enters the bloodstream of affected animals and is transported through the body.
		A diagnosis of prussic acid poisoning is made on clinical and/or post-mortem findings and by the recovery of the poison from the plants/feed and from the animal.

	Prussic Acid and Green Flax (Site not responding. Last check: 2007-09-17)
		Reactions to prussic acid poisoning are swift and lethal.
		Also, extending the storage time of the forage should reduce the prussic acid to a safe level before being fed. It should be noted that a prussic acid test from a feed analysis laboratory would be required before allowing access to the harvested forage.
		Again, a prussic acid analysis from a feed analysis laboratory is required before attempting to swath graze a flax crop.

	PRUSSIC ACID POISONING
		Prussic acid is often referred to by several other terms, including; hydrocyanic acid, hydrogen cyanide, and cyanide.
		Prussic acid poisons by interfering with the utilization of oxygen by the animal tissues, resulting a form of asphyxiation.
		Prussic acid poisoning is sometimes confused with nitrate poisoning because of the similarity of their clinical signs.

	DCT - Prussic Acid Poisoning
		Prussic acid poisoning occurs in ruminant animals that consume plants which contain high levels of hydrocyanic acid.
		Prussic acid poisoning occurs when high levels of hydrocyanic acid are present in very young and drought stressed, frost injured or wilted plants of the sorghum family.
		Remember that levels of hydrocyanic acid reduce with the drying or haying process and the potential for nitrate poisoning remains with the forage throughout the drying and storage process.

	Soil Test Note - No. P001
		Hydrocyanic acid (HCN) or prussic acid is generally not found in healthy plants but is formed by enzymatic action on compounds called the cyanogenetic glucosides (dhurrin) when growth is adversely affected.
		Although prussic acid is not often a problem in horses, feeding sorghum type forage to them may produce a malady known as “crystitis syndrome.” The exact cause of the disease is not known, but forage from sorghum-type plants has been a constant factor in every outbreak.
		The prussic acid potential of hay decreases during the curing stage and is only dangerous if improperly cured.

	Texas Agriculture Extension - Navarro County News Release (Site not responding. Last check: 2007-09-17)
		The young shoots and green tips of plants are high in prussic acid and when cattle graze a field of a sorghum-sudan cross hybrid they select the lush growth first and thereby get that part of the plant highest in prussic acid.
		The prussic acid prevents oxygen from being transferred from the blood to the cells of the cow's body.
		Prussic acid will not remain in a plant for long after it is cut and drying.

	Prussic Acid Danger (Site not responding. Last check: 2007-09-17)
		Prussic acid is found in both cultivated and native forages.
		Plants of the sorghum family may have toxic levels of prussic acid in growth that follows either frost, a severe period of drought or a period of heavy trampling or physical damage.
		Prussic acid poisoning is not cumulative and, therefore, upon removal from a forage source, animals not showing evidence of being poisoned will not likely be affected adversely.

	Prussic Acid Article
		The prussic acid enters the blood stream and combines with hemoglobin to form cyanoglobin which inhibits the ability of cells to take up oxygen from the blood.
		Most sorghums are known for having high levels of prussic acid and therefore are generally not recommended for grazing, although there are some "grazing" varieties that have been developed that are reasonably safe.
		Prussic acid isn't a problem in properly cured hay because up to 75% of the prussic acid dissipates while curing.

	LIVESTOCK AND PRUSSIC ACID POISONING
		The danger of prussic acid poisoning is greatest when livestock graze forage sorghum varieties and crosses, less when they graze sorghum-sudangrass crosses, and least when they graze sudangrasses.
		However, given the volatile nature of prussic acid, even if the lab analysis indicates a potential for prussic acid poisoning the actual forage may be safe to eat after the stems have become dried, cracked and have allowed the toxic gas to escape.
		Because sudangrass and sudangrass hybrids pose the lowest prussic acid poisoning potential, they should be planted for pasture use, instead of sorghum and sorghum sudangrass hybrids.
