Were used 100 pigs YL x CC21 castrated males and females (1:1) 70 days of age and live weight of 21.0 kg to study the effect on the main animal performance traits including handmade cassava silage replacing sugar cane molasses type B as an energy source in the diet. The pigs were distributed according to a randomized block design in two experimental treatments, two replicates (position in the house) and 25 repetitions for each replicate treatment. The diets of each treatment were: T1, control, where the energy source of the diet was sugar cane molasses type B and T2, which replaced 50% of molasses type B by rustic cassava silage. A low level of protein in both diets, were given. There were significant differences (p <0.01) for feed intake of dry matter, kg DM/day (2.80, 2.88) and (p <0.05) for feed conversion, kg DM/kg gain (3.63 and 3.74). There were no significant differences between treatments for weight gain, g/day (770 and 769 and final weight, kg (95.12 and 94.89) respectively. Assay results indicated that the handmade cassava silage, supplemented properly, can be used as energy source in growing-fattening pigs feeding without affecting performance traits, allowing a significant reduction in the food importation for this category.
