The growing competitiveness of the dairy agribusiness increasingly requires improved skills on the part of farmers. The improvement of the productive potential of dairy animals requires more efficient and balanced feeding in order to provide a real increase in production. Whether in the beef or dairy livestock segment, the Brazilian exploratory model combines herd pasture feeding with roughage supplementation in the period of food shortage, as well as energy supplementation. In such a model, the farmer is increasingly sure that the practice of silage is the guarantee of abundant and quality feed. Corn stands out among the species used for the production of preserved forage in the form of silage, or grains for energy supplementation. In this project, agronomic and nutritional characteristics of ten corn cultivars marketed with different texture of the endosperm were evaluated, as well as the ruminal degradability of starch from grains of cultivars with different textures. The dry matter productivity levels of the evaluated cultivars were similar. It was found that vitreous our tooted corn grain endosperm did not provide changes in the nutritional characteristics of the silages produced with the different cultivars. However, the starch from tooted corn grains was more rapidly degraded in the rumen than the starch from vitreous corn cultivars.
