When the plant wilts, its cells rupture and the prussic acid is freed from the sugar molecule. “Accumulation is mostly in younger leaves and new growth, with drought usually the cause of such poisoning,” he adds. But problems occur when environmental conditions slow plant growth, causing the sugar molecules to accumulate in the plant, Wright says. Prussic acid, according to Noble Foundation consultants, is usually attached to a larger sugar molecule, is part of the normal growth process in problem plants, and is usually not harmful to the animal. Hays and silage from high-risk plants may remain toxic.” Drying or ensiling forages tend to have a small effect on nitrate levels. “Free nitrite in the rumen is readily absorbed into the bloodstream, where it destroys the blood's ability to absorb and carry oxygen. “Nitrate poisoning occurs when excessive nitrate is consumed and converted to nitrite faster than the animal can use it,” Wright says.
However, anything that hinders plant growth can cause nitrate accumulation, mostly in plant stems. Nitrogen absorbed by plant roots and transported through the stems is typically used by the plant about as fast as it's absorbed from the soil. Sorghum-related forages are often the most susceptible to toxin accumulations.” How toxins develop Even extended cloudiness can cause toxins to accumulate in a plant. Conditions like drought and freezes can shock the plant. “When the process is interrupted, danger can exist. “There are growth processes that go on in all plants, including bermudagrass, sudan, Haygrazer, ryegrass and crabgrass,” he says. Wright says the physiology of plants can change and create toxins that can harm cattle. The private, nonprofit foundation serves ranchers and other producers in a 47-county area across southern Oklahoma and northern Texas.
It's not a common occurrence, but poisonous nitrates or prussic acids can form in everything from bermuda or ryegrass to alfalfa, says Clay Wright, livestock consultant for the Samuel Roberts Noble Foundation in Ardmore, OK. If nature plays tricks with drought, too much rain or even too many clouds, your high-quality fodder can become a toxic nightmare that can poison some or all your cattle. 2.While it's not nice to fool Mother Nature, the opposite isn't much fun, either.
