En el primer experimento se emplearon 27 conejos de la raza Nueva Zelanda blancos con edad de 35 días y un diseño completamente al azar con arreglo factorial de 2x2x2+1. Los animales se alojaron en baterías de dos pisos dotadas de pasteras, bebederos y porta bloques. Hubo diferencias significativas (P and lt; 005) en consumo de materia seca entre tratamientos registrándose el mayor consumo con concentrado comercial (5440 g) No hubo diferencias en el consumo por efecto de los forrajes, ni por el nivel de úrea pero si por el uso de salvado de arroz (3132 Vs 3930 g). Hubo diferencia significativas (P and lt; 001) para la ganancia de peso diaria entre tratamientos siendo mayor en el concentrado (35.9), por efecto del forraje, siendo mejor con nacedero (17.85); por efecto del uso de úrea siendo mejor sin úrea y por efecto del uso de salvado (20.8 g\d). Para la conversión hubo diferencias significativas (PSummary
In the first experiment, 27 White New Zealand rabbits, 35 days old, were used within a completely randomized design in a 2 x 2 + 1 factorial arrangement. Animals were allocated in two-story wire battery cages with waterers, forage feeders and block-feeders. There were significant differences (p and lt; .05) for dry matter consumption among treatments, having the greatest consumption commercial feed (CC : 5440 g). There were no differences for forages consumption, either for urea level but there were differences due to rice bran consumption (3132 g v.s, 3390 g). There were significant differences (p and lt; .01) for daily weight gain among treatments, being greater for CC (35.9), for forages was better Trichantera gigantea (17.85) and for rice bran was better to add it (20.8), for urea was better without it. In feed efficiency there were significant differences (p and lt; .05) among treatments, being better for CC (3.1), for forages was better Trichantera gigantea (4.5), for rice bran was better to use it (4.02). The best net benefit was for Trichantera gigantea and rice bran ($ 2119). In the second experiment, 20 rabbits were used within a random experimental design There were highly significant differences (pKeywords
