Abstract: The management of swine wastewater is of great importance where swine breeding is considerable and can represent an important fertilizer at maintenance of forages. The objective was to identify the Urochloa brizantha cultivar more responsive to fertilization with swine wastewater. The experimental design was in randomized blocks, with a 3 × 5 factorial scheme and four replications. The treatments consisted of three Urochloa brizantha cultivars (Marandu, Xaraés and Piatã) and five swine wastewater doses (0.0; 3.5; 7.0; 10.5 and 14.0 g dm3 pot-1). The experiment was carried out in a greenhouse in the city of Cuiabá-MT. Three cuts were performed in the aerial part of the plants with intervals of 30 days between them. The application of the swine wastewater, regardless of the cultivar provided an increment in the production of dry mass, plant height, number of tillers, number of leaves and crude protein content, besides reducing the neutral detergent fiber and acid detergent fiber contents. The swine wastewater can be used as an alternative in the fertilization of Urochloa brizantha, because the cultivars were responsive to fertilization.
