AB  - In the semiarid and subtropical regions of northeastern Mexico, leaves and pods of <I>Leucaena </I>sp. are important forage complements into ruminant feeding. In order to determine the effectiveness of the use of <I>Leucaena </I>as<I> </I>fodder,  samples of leaves of four species <I>L. diversifolia</I>, <I>L. leucocephala</I>,<I> L. pulverulenta</I>,<I> L. shannoni </I>and the hybrid <I>L. leucocephala</I> K743 were collected for estimation of some of their chemical characteristics, cell wall components, mineral composition, Volatile Fatty Acid (VFA) concentration and tannin and mimosine content. Results from chemical analysis revealed significant (p< 0.05) differences in nutrient values between species and hybrid of <I>Leucaena</I>. The highest value of crude protein (27.4%) and lowest ash content (7.9%) were exhibited by <I>L. leucocephala</I> K 743, while the highest NDF (38.5%) and ADF (26.8%) content were observed in <I>L. pulverulenta </I>and <I>L. diversifolia</I>. Low level of hemicellulose and soluble ash was observed in <I>L. pulverulenta </I>(7.3% and 0.11% respectively). The maximum mimosine content was observed in <I>L.  leucocephala </I> (3.02%)  and <I>L. pulverulenta</I> (2.91%)<I>.</I> The VFA was higher in <I>L. diversifolia </I>(55.6mM) and <I>L. leucocephala </I>(51.5 mM) compared to <I>L. pulverulenta </I>(42.0 mM) and <I>L. shannoni</I> (48.3 mM).<I> L. leucocephala </I>had higher content of iron (115.5 ppm), lead (2.02 ppm) and aluminum (133.2 ppm) compared to others species, whereas, <I>L. diversifolia </I>showed the higher values in zinc (14.3 ppm), cobalt (0.06 ppm) and manganese (36.8 ppm). The leaves of <I>Leucaena </I>sp. should be considered as different entities than other ingredients of the traditional diets when characterizing nutrient quality.
