** Senecio Weed Poisoning: Please be aware of what weeds are available to your horses. some are harmless, some are deadly! Sadly 5 horses have passed in the Natal area due to senecio poisoning - apparently senecio was found in the bales of hay being fed. ** Senecio vulgaris, often known by the common name common groundsel, a member of the Asteraceae family and Senecio genus, is a tenacious annual herb occurring as a weed in suitable disturbed habitats worldwide. ** Recent studies claim that the lethal amount that cattle or horses need to consume is 7% of their body weight (example: 50 pounds (23 kg) would need to be consumed by a cow weighing 700 pounds (318 kg)). Lesser amounts cause the liver to lose function but is not apparent until the animal is stressed (by new feed or location, pregnancy, a different toxin, etc.).
