          Abstract

          The nutritive value of maize ear for rabbits was determined by substitution of a standard diet (diet C) with 20 and 40% of maize ear (diets M20 and M40). Two experiments were carried out. In the first one, digestibility trials for dry matter (DM), crude protein (CP) and gross energy (GE) were performed with 24 rabbits. In the second experiment, 200 young rabbits were divided in two groups at weaning (28 d) and fed ad libitum with diets C and M20 up to 63 d of age. Feed intake and live weight gain were recorded from weaning to slaughter, and feed conversion ratio was calculated. The principal component of maize ear is the grain (88%) and, consequently, the chemical composition of maize ear is similar to corn, except for its higher fibre content. The digestibility coefficients of DM (64, 66 and 70% for C, M20 and M40) and GE (61, 65 and 70%) increased (p<0.001) with inclusion of maize ear in diet, but digestibility of CP was not affected. Digestible energy and digestible protein contents of maize ear were 15.2 MJ and 40 g kg-1 DM. Rabbits fed with diet M20 presented lower feed intake than those fed with diet C (102 vs 107 g DM day-1; p<0.05) but similar live weight gain (45 g day-1) and, consequently, feed conversion ratio was lower in M20 group than in C group (2.28 vs 2.39; p< 0.001). Results from this experiment show that the inclusion of maize ear in the diet increases the digestible energy content, reduces the voluntary feed intake and improves feed conversion on fattening rabbits.

          Se determinó el valor nutritivo de la mazorca de maíz a partir de una dieta estándar (dieta C), mediante la sustitución de 20 y 40% de la mezcla base por mazorca (dietas M20 y M40). Se hicieron dos experimentos. En el primero se determinó la digestibilidad de materia seca (MS), proteína bruta (PB) y energía bruta (EB) mediante un ensayo de digestibilidad con 24 conejos. En el segundo, doscientos conejos destetados a los 28 d de vida fueron divididos en dos grupos y alimentados ad libitum con las dietas C y M20 hasta los 63 días de edad, registrando la ingestión de alimento y la ganancia de peso vivo, y se calculó el índice de conversión. El grano es el principal componente de la mazorca (88%) y, por ello, la composición química de ésta es muy similar a la del maíz grano, pero con mayor contenido de fibra. Los coeficientes de digestibilidad de MS (64, 66 y 70% para C, M20 y M40) y de EB (61, 65 y 70%) aumentaron (psO.001) con la inclusión de mazorca en la dieta, pero no se afectó la digestibilidad de la PB. Los valores de energía digestible y proteína digestible de la mazorca fueron 15.2 MJ y 40 g kg-1 MS. Los conejos alimentados con M20 mostraron una menor ingestión que los alimentados con la dieta C (102 vs 107 g MS día-1; p<0.05) pero similar ganancia de peso (45 g día-1) y, por ello, el índice de conversión fue menor para el grupo M20 que para el C (2.28 vs 2.39; p<0.001). Los resultados de este experimento muestran que la inclusión de mazorca de maíz en la dieta de conejos de cebo aumenta el contenido en energía digestible, reduce el consumo voluntario de alimento y mejora el índice de conversión.
