In the Brazilian semiarid, depending on the adaptation of cactus of edaphoclimatc conditions, this forage has been used on a large scale, becoming the main bulky power supply flocks. However, its use has been restricted to the dry season, with high costs of labor for cutting and supply directly into the trough. The form of crop can also compromise the potential for regrowth of cactus, since its use is uneven and distributed throughout the dry period. Thus the objective was to evaluate the chemical composition, microbial populations, the fermentation profile, losses in silage and aerobic stability of silage additives palm with urea and wheat bran. To maximize the palmais with application of conservation techniques. The experiment was carried out in the Forage Section of the Federal University of Paraiba. We used a completely randomized design with four treatments represented by different wheat bran levels (0, 5, 10, 20% wheat bran based on dry matter) and four replicates per treatment. For the aerobic stability test were made 32 silos with their bran additions, with and without the addition of 1% urea on dry matter, we used a completely randomized design, arranged in a 5x2 factorial arrangement with five four of wheat bran levels x or without addition of urea. The cactus is a cactus that had percentage of dry matter of 12 (% DM), buffer capacity 22 (mEq / 100 g DM) and soluble carbohydrate (120 g / kg of silage). These characteristics associated microbiology, pH and percentage of organic acids possibly favored its fermentation process. Their qualitative characteristics were also evaluated, palm presented neutral detergent fiber 31 (NDF%), crude protein 6 (CP%). These characteristics possibly favor the fermentation process ideal for silage palm.
