Preferencia de Rumiantes Por el Follaje de Árboles, Arbustos y Herbáceas en la Zona Baja Del Estado Trujillo

An experiment was carried out in order to determine the preference of cattle, ovines and goats for nine fodder potential species ( Acacia spp., Bauhinia cumanensis , Erythrina fusca , Bulnesia arborea , Capparis odoratissima , Cassia alata , Hibiscus rosa-sinensis , Pentaclethra macroloba y Wedelia aff. caracasana ) using a experimental Latin square desing with period of evaluation of nine days in Trujillo state, Venezuela. The foliages were evaluated in terms of the chemical composition (CP, NDF, GE and ash), the concentration of secondary metabolites (phenols, condensed tannins, precipitant tannins and total terpenoids (TT)) and in situ ruminal degradability (DMD and OMD). Statistical differences of nutritional compositor of foliages were observed (P<0.05). Cattle, ovines and goats intake were positively related to each other. The acceptability of cattle was not related to the chemical composition. However, goats preferred the forages with low TT concentrations and ovines preferably consumed foliages with low protein content. No relationship among ruminal degradation and secondary metabolites level was observed. B. cumanensis, H. rosa-sinensis, W. aff. caracasana, E. fusca and P. macroloba exhibited the best results. The evaluation of forages with different types of ruminants allows establishing selection criteria for the implementation of silvopastoril systems.Se efectuó una prueba en condiciones de estabulación para determinar la preferencia de bovinos, ovinos y caprinos por nueve especies con potencial forrajero ( Acacia spp., Bauhinia cumanensis , Erythrina fusca , Bulnesia arborea , Capparis odoratissima , Cassia alata , Hibiscus rosa-sinensis , Pentaclethra macroloba y Wedelia aff. caracasana ) mediante un diseño experimental cuadrado latino con periodo de evaluación de nueve días en el estado Trujillo, Venezuela. Los follajes se evaluaron en términos de la composición química (PC, FDN, EB y ceniza), la concentración de metabolitos secundarios (fenoles, taninos condensados, taninos que precipitan proteínas y terpenoides totales (ET)) y la degradabilidad ruminal in situ (DMS y DMO). Se observaron diferencias estadísticas en la composición nutricional de los follajes (P
