"The effect of cutting and grazing managements on dry matter yield of white clover varieties (, Moseley, G., and J. R. Jones. [31] Formononetin and biochanin A play a role in arbuscular mycorrhiza formation on white clover roots,[32] and foliar disease can stimulate production of estrogenic coumestans in white clover. 2012. [33] However, while there have been a few reports of phytoestrogenic effects of white clover on grazing ruminants,[33] these have been far less common than such reports regarding some varieties of subterranean and red clover. White clover is also reported to become estrogenic if infected with various fungi … Though the toxin remains deadly for approximately the first 24 hours after ingestion, the odds of survival increase dramatically if the patient survives for a few hours. Orr, R. J., A. J. Parsons, P. D. Penning, and T. T.

A person’s diet, acidity of urine may affect susceptibility to UTIs. Plant and Soil 253, no. A 7- to 10-day period on the sweet clover hay, followed by an equal time on the alternative hay, can prevent poisoning but it will not completely prevent prolonged bleeding times. It is high in protein, has beta carotene, vitamin C, most of the B vitamins, biotin, choline, inositol, and bioflavonoids. Immune system may be at fault. White clover is commonly grown in mixtures with forage grasses, e.g. [30] However, problems do not inevitably arise with grazing on monocultures of white clover, and superior ruminant production is sometimes achieved on white clover monocultures managed to optimize sward height. White clover can tolerate close mowing and grazing, and it can grow on many different types and pHs of soil (although it prefers clay soils). When planting, bury rhizomes or stolons 2 in.

Kenneth Olsen, Ph.D., Washington University assistant professor of biology in Arts & Sciences, is looking at the genetics of a wide variety of white clover plants to determine why some plants do and some plants don’t make cyanide — what biologists call polymorphism, or two types. Olsen and colleagues are also testing hypotheses on why acyanogenic plants occur in cold climates. [4][5][6][7][8][9][10] The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length.

"Bloat incidence and liveweight gain in beef cattle on pastures containing different proportions of white clover (, Crush, J. R., and J. R. Caradus. “We are documenting the effect of natural selection at the DNA sequence level to understand the molecular evolution of this polymorphism,” said Olsen. Though not all flowers are safe to eat, edible flowers offer a burst of flavor, color and maybe even health benefits. “The advantage of the clover cyanogenesis system is there’s already so much known about its ecology,” Olsen said. That’s because some clovers have evolved genes that help the plant produce cyanide — to protect itself against little herbivores, such as snails, slugs and voles, that eat clover.

"The digestion of perennial ryegrass (, Evans, D. R., and T. A. Williams. If something damages the cell, these two compounds come into contact with each other and free cyanide is released.”. One poses that there are fewer herbivores in colder climates. If this is the case, then it would be inefficient for clovers to manufacture the Li enzyme. And grass-eating doesn't usually lead to throwing up -- less than 25% of dogs that eat grass vomit regularly after grazing. However, when ingested in large enough quantities in small animals, it can result in poisoning in dogs, cats, and even humans. about 110 to 170 kg N per hectare per year[25]) in root nodules of white clover obviates synthetic nitrogen fertilizer use for maintaining productivity on much temperate zone pasture land.
