Do Photinias harm animals?
Staycalm Wrote: "hannarose" wrote in message ...- Help! Do photinias harm horses? We have a stud farm in Victoria and someone told us photinias harm sheep, what about horses. We breed thoroughbreds and have planted a hedge of photinias near our stallion yards. We may need to move them or fence off if they are poisonous. -- hannarose- From this site: http://tinyurl.com/43qhx "Photinia spp. - Photinia The evergreen photinias are popular ornamental shrubs grown for their round clusters of white flowers, red berries, and particularly their red new leaves in the spring. Cuttings from these shrubs can be poisonous because they contain hydrocyanic acid similar to Prunus." and then from the info about Prunus: "Poisonous principle: Hydrocyanic acid (also called prussic acid), which is one of the decomposition products formed by the action of enzymes on the glycoside amygdalin. Many factors appear to contribute to the formation of the acid, but it is most commonly found when the leaves are partially wilted. When fresh leaves are eaten, they release hydrogen cyanide (HCN) in the stomach or rumen after mastication. Parts of plant: Leaves, twigs, bark, or seeds. Discarded fruit pits should not be available to dogs or caged birds. Periodicity: Spring, summer, and fall; fresh, or wilted due to frost, drought, or broken branches. Animals poisoned: Cattle, horses, sheep, goats, dogs, and birds." Sound pretty noxious. Liz Thank you Liz, I will take this into serious consideration. I don't think we'll be taking any risks. -- hannarose |
