Two experiments were carried out to determine nutritive value and verify performance of growing and finishing swine feed high moisture corn silage (HMCS) and reconstituted silage (RS) of higher oil corn. The digestibility assay was carried twelve cross breed barrow, were allotted in metabolism cages, in a completely randomized design. The values of digestible dry matter (DDM), digestible protein (DP), digestible starch (DS), digestible ether extract (DEE), digestible organic matter (DOM), digestible energy (DE) and metabolizable energy (ME) were for DG, HMCS and RS; 83.42, 7.54, 63.90, 4.40, 82.28%; 3,587 and 3,513 kcal/kg; 60.80, 4.85, 45.01, 3.10, 59.50%; 2,647 and 2,509 kcal/kg; 66.48, 6.16, 49.04, 3.41, 65.67%; 2,853 and 2,797 kcal/kg, respectively, based on natural matter. In the performance experiment thirty-two cross breed swine were distributed in four treatments in a completely randomized design, with four experimental units and two pigs per experimental units. The treatments consisted of a basal corn and soybean meal diet and three diets with total replacement of common corn by DG, HMCS and RS higher oil corn based on the digestible energy. No differences were found among the treatments in the growing phase. In finishing phase, daily feed intake increased for the HMCS when compared with the control diet. The price of the diet per kilogram gain of body weight for the HMCS had decreased, in growing phase and finishing phase. It was concluded that the DG, HMCS and RS, could totally replace the common corn on growing and finishing diet, without impairing performance. Diets with high moisture corn silage resulted in smaller cost per kilogram of produced animal.
