El objetivo de esta investigación fue evaluar la preferencia de forrajes empleados comúnmente en la alimentación animal en zonas tropicales de México. El forraje de guasimo (Guazuma ulmifolia), cocohite (Gliricidia sepium), pasto remolino (Paspalum notatum), pasto Egipto (Brachiaria mutica) y pasto humidicola (Brachiaria humidicola) fueron ofrecidos simultáneamente a 24 conejos Nueva Zelanda durante 14 días. En esta investigación se demostró que Gliricidia sepium y Brachiaria mutica fueron preferidos en comparación con Guazuma ulmifolia, Paspalum notatum y Brachiaria humidicola (P<0.05). El consumo de proteína cruda, fibra detergente ácido, y fibra detergente neutro fueron mayores con Gliricidia sepium y Brachiaria mutica (P<0.05). En conclusión, Gliricidia sepium fue preferido por conejos de engorda. El contenido de nutrientes no tuvo relación con la preferencia de consumo. El estudio de la preferencia de forrajes y su relación con su contenido nutricional es necesario para la inclusión de recursos tropicales en la alimentación de conejos.
