Prophylactic measures are the destruction of mimosine by heat (above 70[degrees]C), the use of chemical additives such as ferrous sulfate, ruminal colonization with the bacteria Synergistis jonesii, or utilization of leucaena in smaller proportion (<40%) for the animal diet (FRANZOLIN-NETO & VELLOSO, 1987).

The lower feed and nutrients intake as well as apparent digestibility values recorded for rabbits fed LLM treatments can be attributed to the possible effect of the anti-nutritional compounds such as mimosine and tannins present in L.
