The semi-arid region may be limited by the dry period of ruminants and the production of ruminants at this time may be limited by the low supply of food per year. The use of forage conservation, such as silage of grasses and legumes of simple cultivation in the region, can be a strategy considered in the systems. Thus, the objective of the present work was to evaluate the effect of the inclusion of forage legumes in the silage of elephant grass BRS capiaçu. A completely randomized design was used, with five treatments and four replications. Capiaçu as the following silage treatments: BRS; 80% BRS capiaçu + 20% leucaena; 70% BRS capiaçu + 30% leucaena; 80% BRS capiaçu + 20% gliricidia; 70% BRS capiaçu + 30% gliricidia. Mini silos were used to compose the experimental plots. The silos were closed with a lid and tape for a period of 30 days. After opening, the ensiled material was homogenized and quartered, and a representative sample was collected for further analysis. The chemistry, pH and composition it creates during manufacturing were evaluated. The silages containing leguminous plants have small species per effluent, also showing promising results with increased crude protein, especially as with leucaena, with crude protein contents of 9.3 and 9.4%. The use of legumes promotes fiber reduction in acid detergent. Adding legumes in the process, is not a legume process, not produced in dry matter recovery materials, all silage seized with juvenile pre-products of dry matter recovery materials. The silages containing 30% of legumes had higher pH values, but close to the recommended, while the other treatments were within the standard containing pH between 3.8 and 4.2. The use of BRS capiaçu silages with legumes can be an alternative for animal feed in the semiarid region. However, the use of capiaçu silage with 30% gliricidia is not prohibited, but its production should be viewed with caution, due to the pH value and because there is no increase in protein.
