Abstract
live weight of 12 ± 2 kg were used. Animals were distributed into two treatments: T0 (corn and protein concentrate) and T30 (inclusion of 30 % of silage in the diet), in equal parts, according to a completely randomized design. Data was analyzed by ANOVA and the comparison of means was made with the Fisher test (P <0.05). Silage presented pH (4.39), temperature (22 ºC), dry matter (30.91 %), crude protein (12.07 %), nitrogen free extract (77.03 %), crude energy (17.88 kJ g DM-1), crude fiber (3.24 %), ashes (4.74 %) and ether extract (2.89 %). There was no effect (P>0.05) for daily food intake (1.15; 1.11 kg), daily weight gain
(0.55; 0.53 kg), food conversion (2.08; 2.09 kg/kg) and final weight (30.50; 29.06 kg) of animals, respectively. The inclusion of 30 % of silage of tubers with taro foliage in the diet of rearing pigs did not affect the productive performance of animals, so it constitutes an alternative food with adequate nutritional characteristics for this category.
