Hibiscus cannabinus L. AND SUGAR CANE B MOLASSES IN DIETS FOR GROWING PIGS WITH DIFFERENT LEVELS OF PROTEIN | USO DEL KENAF (Hibiscus cannabinus L) EN DIETA PARA CERDOS EN CRECIMIENTO CON MIEL B Y DIFERENTES NIVELES DE PROTEINA

espagnol; castillan. No existen antecedentes sobre el uso de harina de forraje de kenaf (Hibiscus cannabinus L.) en la alimentación del cerdo. La harina de kenaf puede considerarse una fuente de proteína foliar (17.6%, base seca) con una alta oncentración de fibra bruta (28.6%, base seca). Se hicieron tres experimentos para estudiar el uso de la harina de kenaf en la nutrición porcina. No se encontró interacción significativa (P0.05) entre los niveles de proteína y la inclusión o no de harina de kenaf en la dieta. Hubo efecto significativo de tratamiento (P0.05) para el consumo de MS (1.34, 1.28, 1.42 y 1.32 kg MS/día). No se encontró influencia del tipo de dieta usada en la ganancia de peso y conversiones alimentarias Los resultados de este estudio demostraron que es posible incluir hasta 20% de harina de kenaf en la dieta de cerdos en crecimiento basada en mieles de caña de azúcar y harina de soya con un nivel de proteína inferior al recomendado para dietas de cereales

anglais. There are no previous information concerning the use of kenaf meal (Hibiscus cannabinus) in pig nutrition. Kenaf meal can be considered a source of foliage protein (17.6 % in dry basis) with a high crude fibre content (28.6 % in dry basis). A third experiment was carried out with 32 YLxD castrate male and female pigs of 11.6 kg initial live weight and 61 days old. A 2x2 factorial arrangement was used to study the effect of two levels of kenaf meal (0 and 20 %) and two levels of protein (14 and 11.2 %) on performance traits during the growing period. There was no significant interaction between the two factors studied. A significant effect of treatment was observed for DM intake (1.34, 1.28, 1.42 and 1.32 kg DM/day). However, there was no effect of diet of the type of diet on mean daily gain and feed conversion Results arising from this study showed that it is possible the inclusion of 20 % of kenaf meal in the diet growing pigs fed sugar cane molasses and soybean meal with a protein level lower than the recommended for cereal based diets.
