dc.descriptionSilages of 13 cultivars (AS243, AS603, Cargill 11, Contiflor 3, Contiflor 7, DK180, M734, M737, M738, M742, Rumbosol 90, Rumbosol 91, V2000 and Media) of sunflower (Helianthus annuus L.) were evaluated for chemical characteristics and in vitro dry matter digestibility (IVDMD). The silages were produced when the plants had >90% ripe grains. The experimental procedure followed an entirely randomized design and the mean values were compared with SNK test (P<.05). The lowest dry matter content (19.8%) was obtained from the hybrid M737, and the highest were from Contiflor 7 (31.2%) and Cargill 11 (32.2%). The pH values varied from 4.1 to 5.5, and the ammonium-nitrogen content as percentage of total nitrogen varied from 5.9 to 14.6%. The averages of obtained lactic, acetic and butyric acids were 7.1, 1.9 and 0.06%, respectively. The hybrid Rumbosol 91 had the lowest percentage of crude protein (7.2%), while >9.0% crude protein was observed in 5 cultivars. The obtained ether extract (EE; 14.7%) was quite high when compared with the other roughages. The neutral detergent fibre, acid detergent fibre (ADF) and lignin contents were 45.8, 35.7 and 6.4%, respectively, and were negatively correlated to IVDMD (general average of 49.8%). The silages had low concentrations of residual soluble carbohydrates. The high ADF and lignin, and the average of IVDMD (49.8%) can restrict the application of sunflower silage and the high EE content can limit the level of inclusion of silage in bovine rations..pt_BR
