The objective of this work to review existing literature on the use of additives sequestering moisture, as well as the use of palm kernel meal as a additive for elephant-grass silage, after that, there was a scientific experiment in which we evaluated the effect of adding bran oil palm as an wet kidnapper additive in elephantgrass silage. The chemical qualitative and fermentation were analyzed in a completely randomized design with six treatments and six replications, where the averages of the results of days of closing and opening were analyzed by regression analysis. In the aerobic stability analysis was employed subdivided plots, so that the treatments were randomized in plots and the evaluation times in the subplots. Samples were collected at the time of ensiling and after 190 days of storage for evaluation of dry matter, crude protein, carbohydrates (total, non-fibrous, watersoluble, cellulose and hemicellulose), mineral material, lignin and lipids. In the days aerobic samples were collected for pH, nitrogen for ammonia, fungi and yeasts. The elephant grass this experiment showed values of 13.9% DM and 8.25% CP while the FD has 77.2% DM and 16.9% CP. The inclusion of FD had a direct influence on the populations of fungi and yeasts during the aerobic stability, the higher the dose, the less proliferation as a result, the values of pH and NH3-N also showed similar behavior. The inclusion of bran Palm at doses in the range of 10% to 15% can be used in silage of elephant, inhibiting undesired fermentation and making them more stable, doses above this value may affect the nutritive value of silage by high lignin content of the additive.
