Hypoglycin A Concentrations in Maple Tree Species in the Netherlands and the Occurrence of Atypical Myopathy in Horses

Background Atypical myopathy ( AM ) in horses is caused by the plant toxin hypoglycin A, which in Europe typically is found in the sycamore maple tree ( Acer pseudoplatanus ). Owners are concerned about whether their horses are in danger if they graze near maple trees. Hypothesis/Objectives To measure hypoglycin A in the most common maple tree species in the Netherlands, and to determine whether concentration of toxin is a predictor of AM in horses. Methods A total of 278 samples of maple tree leaves, sprouts, and seeds were classified by species. Mean concentrations of hypoglycin A were compa... Mehr ...
