Locoweed By: Jessie, and Kayla
How to identify it?!?!?! • It is a leafy perennial with short stems and compound leaves that grow in tuftlike forms from a single taproot. Some species may be covered with silvery hairs. The flowers are often white or purple.
Where it Grows • It grows in the West and Southwest in North America. • It is often found in dry, sandy soil.
Dangers • Locoweed contains a toxic element called Swainsonine. • The whole plant is toxic. Horses become unpredictable and dangerous when eaten, and slowly become paralyzed. • When ingested more than 30% of the body weight it affects the horse’s brain over a period of about 6 weeks or longer. • Since it is not very palatable, horses won’t eat it. However they can become “addicted” to it.
Symptoms • Loss of sensory and motor nerve function, central nervous system depression, progressive loss of coordination, inability to eat and drink, as well as fetal death and birth defects. • Signs of affected horses: they may bob their heads, and adopt an exaggerated, high-stepping gaits or stagger and fall.
Treatment • There is no treatment for seriously affected horses, and its effects are irreversible. • Horses with less severe poisoning may recover when access to the weed is removed.
