CAB-JIMENEZ, Francisco Enrique et al. Foliage composition and digestibility of some tropical forage trees of Campeche, Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2199-2204. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i11.798.
In order to evaluate their potential as an alternative foraging resource, the chemical composition, digestibility and antinutritional factors of Lysiloma latisiliquum, Senna racemosa , Bauhinia divaricata, Senna pendula, Albizia lebbeck, Piscidia piscipula, and Lonchocarpus rugosus, were determined. Plant material was collected from different, previously selected sites during the dry and rainy seasons. A. lebbeck showed the greatest crude protein (CP) content in the dry season (24%), while in the rainy season it was for S. pendula (21.8%). The greatest percentages of NDF (66.8) and ADF (46.2) were found in A. lebbeck in both seasons. The greatest lignin fraction was found in L. latisiliquum in the dry season (12.8%) and in L. rugosus in the rainy season (25.4%). The trypsin inhibitor was found in all species, and hemagglutinins in L. latisiliquum and L. rugosus, but not at toxic levels. There were differences (p< 0.05) regarding in situ digestibility among the legumes in both seasons. The greatest digestibility of DM was for S. pendula (89.1 and 85.0%), and the lowest for L. rugosus (40.1 and 48%), in both seasons. It is concluded that the dry season is the better period to use these shrub legumes given nutrient availability and management strategies must be suitable for plant survival.
