To identify the potential of tropical shrub leaf flour fiber composition and in vitro digestibility of Cratylia argentea, Gliricidia sepium, Erythrina sp., Tithonia diversifolia and Morus alba , were determined in analyses after 17 and 20 weeks of regrowth. Regarding the NDFcontent, M. alba and G. sepium presented the lowest percentages (49 %). M. alba was the species that presented the lowest ADF content (32 %) and the highest ADF contents were, after 17 weeks T. diversifolia and after 20 weeks Erythrina sp., similar to that of C. argentea (53 %). M. alba had the lowest crude fiber content (37.8 %); the highest levels were presented by Erythrina sp. (51.1 %) and C. argentea (48.2 %). The species with the highest digestibility was M. alba (94 %). Less digestible species were C. argentea (62 %) and Erythrina sp. (58 %).
