Leucaena leucocephala, commonly known as leucaena, is a small fast-growing mimosoid tree native to southern Mexico and northern Central America (Belize and Guatemala). It is now naturalized throughout the tropics including parts of Asia. The tree is used for a variety of purposes, such as fencing, soil fertility, firewood, fiber, and livestock fodder. The legume provides an excellent source of high-protein cattle fodder. However, the fodder contains mimosine, a toxic amino acid. Horses and donkeys which are fed it lose their hair. In many cases this acid is metabolized by ruminants to goitrogenic DHP [3-hydroxy-4 (1H) pyridone] in the rumen, but in some geographical areas, ruminants lack the organisms (such as Synergistes jonesii) that can degrade DHP. In such cases, toxicity problems from ingestion of Leucaena have sometimes been overcome by infusing susceptible animals with rumen fluid from ruminants that possess such organisms, and more recently by inoculating cattle rumina with such organisms cultured in vitro. Such measures have facilitated Leucaena use for fodder in Australia and elsewhere.
