GARCIA, Danny Eugenio et al. Nutritional Characterization of Six Fodder Species Foliage With Emphasis in Their Polyphenolic Profiles.. Rev. Cient. (Maracaibo) [online]. 2008, vol.18, n.2, pp.188-196. ISSN 0798-2259.

An experiment was carried out in order to evaluated the DM ruminal degradability parameters (a, b, a+b and c), 48 hours degradation of DM, CP and NDF and CP intestinal digestibility in matures sheep of Enterolobium contortisilicum, Lysiloma latisiliquum, Moringa oleifera, Morus alba, Schizolobium excelsum and Trichantera gigantea at Trujillo State, Venezuela. All forages showed substantial differences regarding proximal composition (P<0.05); while L. latisiliquum and S. excelsum showed the highest polyphenolic compounds level. E. contortisilicum exhibited superior DM degradation (a: 31.1%) and M. alba showed considerable degradable fraction and degradation potential (b: 71.2% and a+b: 92.8%, respectively). The forages degradation rate not showed significant differences to each other (P>0.05). M. alba showed the highest 48 hours DM degradability (86.5%), CP (84.4%) and NDF (73.5%) and E. contortisilicum and M. oleifera a superior posruminal protein digestibility (39.0 y 37.8%, respectively). Based on their chemical compositions, the evaluated feed with higher potential to be used for fed ruminants are: E. contortisilicum, M. oleifera, M. alba and T. gigantea. Its speculated that the lowest nutritive value of L. latisiliquum and S. excelsum for feeding ovines perhaps is due to the presence of polyphenolic compounds.
